Doppler Flow Meter - DFM 5.0 - Greyline Instruments - #1

Text version of the page

Simple, Non-Contacting Flow Meter for Accurate Flow Measurement from Outside a Pipe Doppler Flow Meter Model DFM 5.0 Displays, Transmits, Totalizes and Controls User-Friendly Calibration Password Protected Isolated 4-20mA Output 2 Control Relays Digital Signal Processing Optional Intrinsic Safety Ideal for “Problem Liquids” External Sensor No Contact, No Maintenance Greyline Doppler Flow Meters monitor the flow rate of dirty or aerated liquids including: wastewater, chemicals, acids, slurries, abrasives and viscous liquids. Recommended for full pipes and any fluid that contains solids or bubbles. The DFM 5.0 strap-on sensor is mounted on the outside of a plastic or metal pipe ½ inch / 12.7 mm diameter or larger. To measure flow an acoustic signal is reflected back to the sensor from moving particles or gas bubbles suspended 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. The DFM 5.0 Doppler Flow Meter includes an ultrasonic sensor, a simple 5-key calibration system, a large digital flow rate display with totalizer, isolated 4-20mA output and two programmable control relays. Data logger and intrinsically safe sensor are optional. Non-Contacting Flow Monitoring and Control Ultrasonic Sensor mounts on any Pipe
