Doppler Ultrasonic Area/Velocity Sensor
Measures depth (using a capacitive pressure diaphragm) and velocity. Access to the monitoring point is required for installation and maintenance.
Doppler Ultrasonic Insert Velocity Sensor
Measures velocity and requires access to the outside wall of the pipe in which the sensor is to be mounted.
Doppler Ultrasonic Velocity Sensor
Measures velocity in full pipes when access to the pipe is available and the pipe can be emptied when installation/maintenance is required.
