FLOW MEASUREMENT AND CONTROL
BADGER Meters are the world leading manufacturer of high quality Electronic Meters for the Water, Process and Oil & Gas Industries. These highly accurate meters ensure that clients can account for every drop of product making them more efficient and increasing revenue. They can measure the flow of liquids and gases in almost all branches of the industry, in small and large applications together with pressurized pipes, partially filled pipes and open channels too with a great variety of measurement principles.
ELECTROMAGNETIC FLOW METERS
Electromagnetic flow meters are ideally suited for flow measurement of all liquids with a minimum conductivity of 5 μS/cm (20 μS/cm for demineralized water). These meters are very accurate and the flow measurement is independent of density, temperature and pressure of the medium.
MEASURING PRINCIPLE : The operating principle of the electromagnetic flow meter is based on Faraday‘s law of magnetic induction: The voltage induced across any conductor, as it moves at right angles through a magnetic field, is proportional to the velocity of that conductor. The voltage induced within the fluid is measured by two diametrically opposed internally mounted electrodes.
Detector type II for is perfect for a variety of applications. It can be configured with up to four electrodes for measuring, empty pipe and grounding electrodes. Detector type III with short lay length makes it more suitable for many applications. Delivered with a PTFE liner, the detector type III has a standard nominal pressure of PN 40.
The sanitary detector was developed for the flow measurement of liquid food. This model is available with Tri-Clamp® BS 4825/ISO 2852, DIN 11851 process connections and also with any special connections (customer specifications). The sanitary detector is delivered in a stainless steel housing and with PTFE lining.
TURBINE METERS
MEASURING PRINCIPLE: Turbine meters are volumetric meters. When the fluid passes through, a rotor is activated and the movement is then either electronically or mechanically transmitted. Turbine meters are best suited for low viscosity fluids and also gases.
Single Rotor Turbine Meters
Pressure, viscosity and temperature compensation provides unbeatable repeatability and linearity. The turbine 
meters can be mounted in any orientation, either on horizontal or vertical pipes. A calibration certificate is issued for each turbine meter by a NVLAP accredited test laboratory and there is also a great number of pulse transmitters, processors and displays available.
Typical applications:
• Measurement of cooling circuit performance
• Measurement of fuel consumption, gear oil, brake fluid and cooling water in calibrators
Dual Rotor Turbine Machines
The Exact series provides the most precise measurement and the widest flow range capability. Often used in aerospace, automotive, industrial and OEM applications. The Exact series meters also utilize a unique
pickoff system, which is highly resistant to external vibration and minimizes space. This allows for direct coupling of electronics on a robust mount which has the benefit of a lower profile. The meter is designed for bi-directional flow and high shock environments.
Typical applications:
• Measurement of cooling circuit performance
• Qualification of jet engines and aircraft components in test calibrators
• Fuel consumption and lubricant measurement
• Monitoring of hydraulic systems, measurement of propellant consumption in aircraft
NUTATING DISC METERS
Nutating disc meters are most suited for measuring flows and volume of low and medium viscosity fluids.
MEASURING PRINCIPLE: Nutating disc meters are positive displacement meters. The top and lower part of the meter chamber are cone shaped. A ball bearing centralizes the disc between the two cones. A nutating motion of the disc is generated when flow enters the meter chamber. Complete separation between inlet and outlet chamber volumes is always achieved by one dedicated disc diameter line. The inlet and outlet parts of the meter chamber are separated by a partition plate. The positioning bar forces the disc to nutate around the center axis of the chamber, driving the transmission magnet.
Meters for clean and moderately dirty fluids
The Recordall® series is a positive displacement meter. The series is best suited for metering fluids up to a viscosity of 700 mPas and at an operating temperature of 50 °C up to 120 °C. The metering chamber includes disc, positioning bar and transmission magnet. The chamber is inserted into the meter body. A screen in the inlet side of the body protects the chamber against penetration of larger solid particles. The meter system is modular and enables the combination of mechanical or electronic displays with any meter size.
Typical applications are: Clean and moderately dirty liquids, hard and soft water, oils, fuel, solvents, etc.
Meters for AdBlue® and aggressive media
The ultra pure 32,5 % urea solution, also known by the name of AdBlue®, is the basis for the reduction of toxic nitric oxides in exhaust gases from diesel operated goods vehicles. AdBlue® is made synthetically. The high purity and quality are DIN V 70070 certified. AdBlue® can be metered with a plastic Recordall® RCDL M 25 or M 40. All Badger Meter registers can be mounted on the meters.
Batch Systems – The electronic displays can be combined with any flow meter. Many of them can be used in hazardous zones. A wide variety of output signals are available.
SMALL CONTROL VALVES
Badger Meter‘s control valves are specifically designed for controlling small to medium flow rates of liquid or vapor, in pipe sizes from ¼“ to 2“. They cover a Cv range from 0.0000018 to 54 in different inner valve sizes.
IMPELLER METERS
Impeller meters are a low cost alternative in irrigation systems (sprinklers, chemical injection processes in water treatment, water management, etc.), in municipalities, in energy management (HVAC, building management, energy consumption monitoring, etc.) and in general industry (batch processes for bakeries, adding color dye to water for textile, food processing, inks, and other color additive mixtures, adding liquid vitamins and nutrients to feed water for livestock, automatization in the film industry, etc.).
MEASURING PRINCIPLE: The series features a six-bladed impeller design with a proprietary, non-magnetic sensing mechanism. The impeller shape coupled with the absence of magnetic drag provides accuracy and repeatability throughout the flow range of the sensors. As the liquid flow turns the impeller, a low impedance square wave signal is transmitted with a frequency proportional to the flow rate.
ULTRASONIC FLOW METERS
Ultrasonic flow meters are most suited for flow measurement of fluids in pressurized pipes as well as in channels and partially filled pipes. The ultrasonic flow meter series Dynasonics® – depending on the model – uses 
the Doppler or transit time method. Applications can be found in water and waste water treatment, cooling in semiconductor processes and in HVAC cooling and heating systems. The rugged construction ensures long life, even under extreme ambient conditions.
MEASURING PRINCIPLE: Ultrasonic signals are alternately sent in and against the flow direction. Ultrasonic
energy bursts are transmitted and received via well-defined paths across the flow stream. The velocity of the flow is accurately measured by the difference in the arrival times of signals from the upstream and downstream transducers. The transit time difference ( t = t 2/1 – t 1/2) determines the average flow velocity.
HEADMETERS AND ACCESSORIES
Heat meters are used in building management, the chemical and petrochemical industry and in the food and beverage industry to measure the heat/cold quantity.
MEASURING PRINCIPLE: Two temperature sensors are installed on the supply and return pipe in addition to the ultrasonic flow meter. The thermal output of a pipe conduit network is based on a measurement of the difference between the supply and return flow temperatures and also the volumetric flow of the heat transfer medium. The energy consumption is calculated by the electronics and can be displayed in units such as kWh, BTU, MBTU, MMBTU, watt, MW, joule, kJ and tons.
212 HEAT CALCULATOR
The 212 heat calculator has been designed to measure the energy consumed in hot water heating systems and chilled water cooling systems. The 212 is supplied with temperature probes and easily interfaces with our electromagnetic flow meters and impeller meters
GSM / GPRS MODULE FOR WIRELESS DATA RECORDING
For consumption monitoring and leakage reduction in water supply systems, precise flow measurement in large channels and rivers for the monitoring of navigability and issue of flooding forecasts, or monitoring and alarm of overflow basins for rainwater, sewage plants, storm water overflow plants as well as for the control of irrigation plants or level monitoring, alarm for automatically filling and connection to the supplying system, Badger Meter offers the possibility to record wireless the measuring data coming from flow meters.
OVAL GEAR METERS
Oval gear meters are volumetric meters and are most suited for liquids with a viscosity up to 5.000 mPas. (special models up to 500.000 mPas.). Typical applications are mineral oils, hydraulic oils, solvents, brake fluids, coolants, transmission oils, etc.
MEASURING PRINCIPLE: As fluid passes through the metering chamber by entering the inlet port, it forces the internal gears to rotate and exits through the outlet port. Each rotation of the gear displaces a given volume of fluid. Controlled clearances between the gears and chamber wall insure minimum leakage. As the gears rotate, a magnet on each end of the gear activates the reed switch and forward the pulses to the display or to the pulse output.
VARIABLE AREA FLOW METERS
The EZ-View® variable area flow meters are rugged, low-cost direct reading meters. They are simple to install in
any orientation, vertically, horizontally or even up side down, etc. without sacrificing measurement performance.
Flow straighteners, located in the inlet and outlet, allow the flow meter to be less sensitive to turbulent flow conditions. Further straighteners or other special installation is not required. EZ-View® flow meters provide instantaneous, direct-reading flow rate measurement of liquids in closed piping systems. The transparent PPSU body allows visual inspection of the fluid condition in addition to allowing the internal flow rate indicator line to be easily seen.
The H-series – VARIABLE IN-LINE FLOW METERS
The unique spring loaded design of this variable area flow meter for common fluids reduces viscosity sensitivity.
The Hedland® variable area flow meters are the most readable products in their class to monitor a wide range of liquids, petroleum-based fluids, phosphate ester liquids, water, water-based fluids or water/oil emulsions. A pneumatic series is also available for metering air and compressed gases.
CORIOLIS MASS METERS
Coriolis mass meters are recommended for the direct, continuous measurement of the mass of flowing liquids independently of their conductivity, density, temperature, pressure and viscosity in the food, chemical and petrochemical industries. They are best suited to measure chemicals, liquid food, suspensions, molasses, inks, lacquers, pastes, etc.
MEASURING PRINCIPLE: A force, the so-called Coriolis force, acts on a mass that is moving towards or away from the point of rotation within a rotating system.
The Coriolis RCT1000 enables the measurement of mass and volume flow, density, concentration and temperature with a single measuring instrument. It is also well-proven for lime milk density measurement. Other typical applications are the dosing of expensive biocides and high-precision fuel supply to burners in power plants where an important increase in efficiency is achieved through direct fuel mass flow measurement.
VORTEX METERS
Vortex flow meters utilize ultrasonic sensing technology, allowing the meters to perform with an extremely small bluff body. As a result, system pressure drop and meter turndown ratio are greatly improved. The meters benefit from a wide measuring range (up to 70:1) and high accuracy (1 % of reading). By using intelligent electronic and HART® communications vortex meters are ideal for biogas, process engineering systems and refineries. The unit has no moving parts and is maintenance free.
MEASURING PRINCIPLE: Within the flow meter, as flowing media moves across the strut or “bluff bar”, vortices are shed. The meter transmits an ultrasonic beam through the vortex pattern of the strut. Electronic transmitters enable the vortices to be counted, and this value is converted into a velocity.
DIFFERENTIAL PRESSURE FLOW METERS / VENTURI TUBES
Venturi tubes are low-cost and work absolutely maintenance-free. Primary flow elements are used to provide accurate differential pressure readings, to obtain flow rate information for gases and liquids and industrial steam processes. Pitot meters are used in applications with water, clean liquids, air, gas and steam producing processes by saturation or heating. The standard pressure and temperature values are in the range of 55 bar and 425 °C. Hot-tap systems are specifically designed for use at high temperatures and high pressures.
MEASURING PRINCIPLE: Pitot tubes also work on the basics of the Bernoulli equation. In contrast to the venturi tube, work is done with the help of a second tube which is oriented parallel to the flow of the medium, such that the flow impinging on a front pipe opening. In front of the tube is formed the dynamic pressure, behind the tube, the static pressure. This remains constant.
HYDRAULIC DIAGNOSTIS
Flo-tech portable hydraulic testers are compact and portable units, designed for fast troubleshooting and diagnostics of mobile and stationary hydraulic systems.
The Flo-Check® USB Hydraulic system analyzer utilizes a data acquisition module to record the operating parameters of the hydraulic system and then transfers them to the user’s laptop computer, where multiple operating parameters (bi directional flow, pressure, temperature, power) may be monitored in real-time.
The diagnostic test equipment MC 4000 is a handheld system analyzer with inputs for two pressure sensors, one temperature sensor, one flow sensor and one active pick-up for RPM1 measurements.
FLUID MANAGEMENT SYSTEM
Oil management systems that dispense volumes of fluids in automotive workshops require highly accurate flow meters and pulse transmitters, trouble-free and secured manipulation in remote transmission equipment in addition to durable data memory that is able to retrieve dispense data, quantities and oil products at any time. The radio frequency based systems with MID approval offer the advantage of a wireless communication between the dispensing terminal and meter.
Wireless oil management systems
The LMS-RF oil management system offers a cable-free communication between the dispensing terminal and meter using radio frequency technology which has been specially developed for garages. The system can communicate with any host computer within the workshop using a free programmable RS 232 interface. In combination with a trolley, the LMS-RF system becomes a fully stand alone unit.
Cabled fluid management systems
The oil management system MDS 2000 has been designed to control and manage lubricants to achieve product accountability and profit center protection. The system is especially designed to be installed in small or large garages, car pools, forwarders and industry. The entry level consists of one alphanumeric access keypad, network linked to one I/O control unit, controlling up to 8 dispensing points each of which with the same fluid/grade.
FLOW CALIBRATORS
Are highly-precise calibrators capable of performing flow calibrations on many types of flow meters. Positive displacement liquid calibrators are volumetric type measurement devices, which measure the exact volume of fluid that passes through the flow meter under test while compensating for changes in viscosity and temperature. They ensure extremely high precision fluid flow measurement. With a repeatability of ±0,01 % of reading, the
calibrators are extremely precise. Metrological institutes from all over the world deploy this type of calibrator for their meter calibrations. The calibrators are easy to maintain and will last 50 years or more in service.
Badger Meter is also able to offer calibration services for manufacturers and users of flow meters. We verify the accuracy of all kinds of flow meters: Electromagnetic, ultrasonic, turbine, oval gear, nutating disc, oscillating piston, impeller, variable area, primary flow elements and heat meters.
Transaction data is retrieved on a standard serial printer. The system upgrades easily to control up to 64 dispensing points, all working simultaneously with multiaccess keypads. Transaction ticket printers can be connected on each keypad to hold the mechanic accountable and/or to print the data at different workshop departments. The data can be archived, restored and exported to the main workshop computer. The system can communicate with any workshop host computer by means of a free programmable RS 232 interface.
SMALL CONTROL VALVES
Badger Meter‘s control valves are specifically designed for controlling small to medium flow rates of liquid or vapor, in pipe sizes from ¼“ to 2“. The choices range from process valves (standard bronze valves, flanged stainless steel or other exotic material), to hygienic valves (barstock or cast, tube or clamp ends), to special valves (3-way, angle, high-pressure, high-temperature and cryogenic). Valves can be made with most flange types and sizes, welded connections, NPT or tube fittings. Although the standard material is stainless steel, many other materials are available for corrosive applications, including solid Titanium and Tantalum.
ReCo® valves for R & D, pilot plants, technical plants and fine batching applications 
The RC series is the classical standard line of small control valves originally developed for pilot plant and research applications for customers in all types of process industries. In addition to standard stainless steel housings, many other materials can be used. The wide range of material combinations, inner valves and other components is almost unlimited.
The pneumatic actuator can be enhanced with positioners, regulators, solenoid valves and pressure gauges, all in a compact design adjusted to the valve size. Upon request, one-of-a-kind valve solutions can be produced.
