Portable Doppler flowmeter: high measurement accuracy and good stability

1、 Product Introduction

BK-LS6 Acoustic Doppler Velocimeter is a flow velocity and flow detection instrument used in rivers, open channels, pipelines, and other working conditions. It adopts ultrasonic detection technology, with high measurement accuracy, good stability, little influence from environmental factors, no rotating parts, low maintenance frequency, and high work reliability. It is the first product for portable flow velocity and flow measurement.

Application: Sponge city, river chief management, inland river monitoring, natural rivers, open channels, pipelines, aquaculture and other scenarios.

Principle: The frequency difference between the transmitted and received ultrasonic waves is related to the flow rate, the time difference between the transmission and reception of ultrasonic waves is related to the liquid level, the static pressure liquid level is used for working conditions that require measuring a large liquid level range, and the environmental temperature measurement is used to correct the actual propagation speed of ultrasonic waves.
