Product Description

HXH03-1 ultrasonic Doppler flow velocity is an ultrasonic flowmeter made using the principle of ultrasonic "Doppler effect". It does not have rotating parts such as propellers or bearings, and uses ultrasonic technology to detect flow velocity without friction or inertia. The measurement point is located in front of the body, without damaging the flow field. It has high measurement accuracy, wide range, sensitive induction, linear flow measurement, is not afraid of sediment and floating debris, intuitive reading, easy operation, and is not easily damaged.
Suitable for measuring flow velocity, direction, and temperature in rivers, oceans, shore observation stations, ships, and buoys, especially suitable for measuring river waters with high sediment content and abundant aquatic plants and debris.

Performance characteristics

★ High measurement accuracy, wide range, capable of measuring weak current and strong current;

★ Sensitive induction, high resolution, not limited by startup flow rate;

Fast response speed, capable of measuring instantaneous flow velocity and average flow velocity;

★ Linear measurement, K and C values without calibration curve;

★ No mechanical rotating parts, no mud blockage or entanglement of water plants, debris, etc., most suitable for measuring in rivers with high suspended solids content and floating objects such as water plants.

■ Function Introduction
