Monitor and Sensor

Greyline Doppler Flow Meters monitor the flow rate of "difficult" liquids including: wastewater, chemicals, acids, slurries, abrasives and viscous liquids. Recommended for full pipes and any fluid that contains solids or bubbles.

The DFM-IV strap-on sensor is mounted on the outside of a plastic or metal pipe. To measure flow an acoustic signal is reflected back to the sensor from particles or gas bubbles in the fluid.

Installation is easy - without shutting down the flow system. No contact is made with the moving fluid and no pipe cutting or drilling is required. There is no fouling or scale build-up on the sensor.
