Displays, Transmits, Totalizes and Controls
Isolated 4-20 mA Output
2 Control Relays
Digital Signal Processing
Optional Intrinsic Safety
Non-Contacting Flow Monitoring and Control Ultrasonic Sensor mounts on any Pipe
Ideal for "Problem Liquids"
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.
External Sensor No Contact, No Maintenance
The DFM 5.0 strap-on sensor is mounted on the outside of a plastic or metal pipe 1/2 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 4-20 mA output and two programmable control relays. Data logger and intrinsically safe sensor are optional.
The DFM 5.0 flow sensor installs without cutting the pipe. It takes just a few minutes to mount on the of any pipe. Calibration is easy with the built-in, 5-button keypad. Select your choice of flow units and enter pipe diameter through the user-friendly calibration menu. Enable password protection to prevent tampering.
Benefits of Non-Contacting Flow Measurement
No Contact means no maintenance, no sensor fouling, no obstruction to flow, no pressure drop, no corrosion and no pipe cutting or drilling for installation.
