1. Introduction
The HGDU Doppler ultrasonic flow meter consists of an ultrasonic flow transmitter, ultrasonic flow sensor, and installation accessories. This flow meter is used specifically to measure the flow rate of liquids in applications such as urban water supply, drainage, river water, sea water and other fluids.

2. Features
1. This flow meter can measure the flow rate of liquid which contain suspended solids or bubbles.
2. It can measure the flow rate in the pipe when said pipe is not fully filled with liquid.

3. Principle
Doppler ultrasonic flow meters are based on sound waves that generate a Doppler frequency shift at the static point. It detects the shift generated by the moving source, then calculates the flow velocity of the scattering body.
