HR7600 DOPPLER OPEN CHANNEL FLOW METER

This flow mater has three functions: measuring the average flow rate, measuring the water depth, measuring the water temperature, and can display the section flow rate.

Water temperature measurement using temperature probe, the temperature probe does not contact with water, close to the top of the instrument packaging material, need to be placed underwater for a certain period of time to reflect the actual water temperature. The purpose of water temperature measurement is to correct the ultrasonic speed in the water and correct the water level value measured by the pressure sensor.

The water depth measurement uses imported high-precision pressure sensors, placed at the bottom of the instrument, and its probe sensing part is in direct contact with the water.

The flow velocity is measured by an ultrasonic probe (transducer) that transmits and receives ultrasonic signals and processes them accordingly: the measured average flow rate, together with the water level and section dimensions, can be used to find the section flow rate.
