Model 5 Portable Doppler Flowmeter

for Dirty Liquids & Slurries

Ideal for measuring full pipe flow of any liquid containing gas bubbles or solids larger than 100 microns and in concentrations greater than 75 ppm. The Portable Ultrasonic Flow Meter is fast and easy to use – you can mount the sensor on the outside a pipe and calibrate the flow meter in just a few minutes. Recommended for “difficult liquids” like wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. Measures flow through most metal and plastic pipes including PVC, steel, stainless steel.

The instrument is AC/DC powered with a built-in battery and charger. With its 4-20mA output you can use the flow meter as a spare transmitter for critical applications. For flow troubleshooting, the RS232 output can be connected to your computer or modem to receive and log flow at programmable intervals. PC software is included with each instrument and data files can be imported to any spreadsheet program for analysis and graphing.

Main advantages

  • No Contact with the liquid
  • No Pipe cutting required: Install without shutting down flow
  • Low-cost: Strap-on Sensor fits any pipe size
  • Optional intrinsically safe Sensors
  • Ideal for “difficult liquids” including raw sewage, treated effluent, stormwater, sludge, slurries abrasives, viscous and corrosive chemicals, performance evaluation, projects, etc.
