Description
ULTRASONIC VELOCITY SENSOR
The SOMFLOW continuously measures the water or effluent velocity in ducts, pipes and open canals in sewer networks, water treatment plants and industrial facilities. The twin 1-MHz ultrasonic Doppler transceiver determines flow velocities from as low as 0.01 m/s to 5 m/s.
FEATURES
- Flow velocity range 0.01 ... 5 m/s
- Versatile installation options
- Waterproof housing that is resistant to aggressive liquids
- Simple integration into existing data acquisition and control systems
- Easily linked to data loggers
- Multiple data interfaces: RS-485, Modbus RTU, SDI-12
