Electronic Flow Meters

An industry leader in both mechanical and electronic flow metering technologies, Badger Meter offers one of the broadest flow control and measurement portfolios in the industry – a portfolio that includes eight out of the ten major flow meter technologies. From electromagnetic, positive displacement, turbine, ultrasonic and variable flow meters to small control valves and a complete line of accessories, we apply our products to develop innovative solutions that deliver precise, accurate measurement information and control.


The Badger Meter RCT1000 Coriolis mass flow meter identifies flow rate by directly measuring fluid mass over a wide range of temperatures with a high degree of accuracy. For fluids consisting of two liquids or two gases, the RCT1000 Coriolis system can derive the concentration and mass of each fluid based on the density measurement. Furthermore, the unobstructed, open flow design makes it suitable for a variety of fluids such as slurries and other viscous, nonconductive fluids that are difficult to measure with other technologies.

Simultaneous measurement of:

  • Mass flow
  • Fluid density
  • Fluid temperature

TFX Ultra: Clamp-on Ultrasonic Flow and Energy Meter.

The TFX Ultra-clamp-on ultrasonic flow and energy meter provides accurate and repeatable liquid flow measurement for full pipes one-half inch or larger. Built for non-intrusive flow and energy measurement applications, the meter attaches to the outside of the pipe and does not contact the liquid being measured. The clamp-on design allows quick and low-cost installation, and eliminates worries of fluid compatibility and pressure head loss. With no moving parts, there is no mechanical wear, so repair kits or replacement parts are not needed.

  • Measurement type: ultrasonic bi-directional flow measurement
  • Liquid types: liquids with small amounts of suspended solids or aeration Ultrapure Liquids to

  • Piping/tubing sizes: ½ inch (12 mm) and above
  • Configurations: flow meter or energy meter
  • Measures energy usage in Btu, mBtu, tons, KJ, kW and mW Add MMBTU
  • Typical Applications: water & wastewater, sewage, HVAC/energy monitoring, power generation, mining, semiconductor, food & beverage, and flow system commissioning and troubleshooting.

DFX: Doppler Ultrasonic Flow Meter. The DFX ultrasonic Doppler flow meter measures flows of liquids containing suspended particles or aerated liquids. The suspended particles must reflect ultrasonic energy. The DFX flow meter operates by transmitting ultrasonic waves into the flow stream and measuring the frequency shift of the reflected wave. The meter’s clamp-on design allows quick and low-cost installation, and eliminates worries of fluid compatibility and pressure head loss. A hot-tappable insertion probe transducer is available for installation on pipe systems that do not permit ultrasound penetration. With no moving parts, there is no mechanical wear, so repair kits or replacement parts are not needed..

  • Measurement type: ultrasonic Doppler flow measurement
  • Liquid types: semi-clean liquids with suspended sonic reflectors
  • Accuracy: ±2% full-scale over calibrated span
  • Interface: 2-line x 8-character LCD
  • Pipe/tubing sizes: 1/4 inch (6 mm) and above, full pipe
  • Power supply: 115/100/230 VAC
  • Optional outputs: 4-20 mA, dual relay and rate pulse
  • Automatic gain control and in-field linearization
