DFM 6.1 Doppler Flow Meter

Pulsar Measurement Doppler Flow Meters monitor the flow rate of dirty or aerated liquids including wastewater, sewage, slurries, abrasives, and viscous liquids. Recommended for full pipes and any fluid that contains solids or bubbles.

The DFM 6.1 clamp-on sensor is mounted on the outside of any pipe 12.7 mm (0.5 in) diameter or larger. To measure velocity an acoustic signal is reflected to the sensor from moving particles or gas bubbles suspended in the fluid. Flow is calculated based on the configured pipe inside diameter.

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.

The DFM 6.1 Doppler Flow Meter includes an ultrasonic sensor, an easy to use 5-key configuration system, a large digital flow rate display with totalizer, isolated 4-20mA output, 26 million point data logger, and two programmable control relays. The sensor is classified as non-incendive for Class I Div 2 locations, and an intrinsically safe sensor is optional, for Class I Div 1 locations.
