BR.HXH03-1 Ultrasonic Doppler Current Meter with Flow Direction

1. Product Introduction

The BR.HXH03-1 Ultrasonic Doppler Current Meter with Flow Direction is an ultrasonic flow measurement instrument based on the "Doppler effect" principle. It has no rotating parts such as propellers or bearings, uses ultrasonic technology to detect flow velocity without friction or inertia, and measures at a point ahead of the device without disturbing the flow field. It features high measurement accuracy, wide range, sensitive response, linear flow measurement, immunity to silt and floating debris, intuitive readings, easy operation, and durability.
