Product details

Instrument Overview
The radar-ultrasonic Doppler flowmeter integrates radar-based flow measurement, ultrasonic flow measurement, radar-based water level measurement, and static pressure-based water level sensing into a single, all-in-one sensor technology. It is suitable for online monitoring in complex or harsh environments such as underground pipe networks for stormwater and sewage, drainage channels, and river discharge outlets.

Product Features

(1) When the pipe is not fully filled, radar wave velocity measurement is used; when the pipe is fully filled, ultrasonic Doppler velocity measurement is employed.

(2) Automatically switch between radar and ultrasonic flow measurement modes based on whether the pipe is full or partially full.

(3) Dual-water-level, dual-flow-rate design for measurement with no blind spots.
