Instrument Overview

The portable ultrasonic Doppler flowmeter is an instrument that measures flow velocity based on the Doppler effect principle. It is used for monitoring water levels, flow velocities, flow rates, and water temperatures in municipal sewage networks, discharge outlets into rivers and seas, agricultural irrigation and drainage systems, industrial wastewater discharge, hospital effluents, aquaculture, hydrological surveys, and other similar applications.

Product Features

(1) Conduct flow velocity measurements at a low water level of 2 centimeters.

(2) Built-in cross-section shape selection and measurement mode selection

(3) Compare or calibrate the flow rate data from on-site equipment.
