Portable open channel flow meter

1.Portable open channel flow meter product introduction

Portable open channel flow meter uses ultrasonic waves through the air to measure water velocity and flow in a non-contact way.Portable open channel flow meter is a flow velocity flow detection instrument used in rivers, open channels and pipelines.It adopts ultrasonic detection technology, with high measurement accuracy, good stability, less affected by environmental factors, no rotating parts, low maintenance frequency, and high working reliability.It is the first choice for portable flow rate measurement.

Principle: In the field of acoustics, when there is relative movement between the sound source and the receiver (i.e., the probe and the reflector), the frequency of the echo will change.This frequency change is called frequency shift, i.e.Doppler effect.The frequency of the sound wave becomes higher when moving towards the observer and lower when moving away from the observer.Portable open channel flow meter calculates the flow rate by calculating the frequency change.

2.Portable open channel flow meter application field

Scenes such as sponge cities, river chief management, inland river monitoring, natural rivers, open channels, pipelines, and breeding.

3.Main features of Portable open channel flow meter

It can measure pipelines, channels, natural river flow, flow rate, and water level.

The single flow rate sensor is convenient to install and suitable for flow measurements such as municipal sewage sewage pipe channels, unsatisfactory pipes, various channels, irregular river channels, natural streams, sewage outlets, etc., and can be installed concealedly, so that long-term and stable work can be achieved.

Instant flow value and cumulative flow value can be provided.

2.8-inch color screen, text and graphics, convenient operation and flow analysis.☆

It can store 10,000 pieces of data and export data through the included USB flash drive.☆

Low power consumption of sensor: power consumption is <0.8W when measuring flow rate.☆

Chinese and English operation interface, supports one-click switching.☆

Built-in rechargeable lithium battery, standby time exceeds 8 hours.

Built-in pressure water level sensor, temperature sensor.

6.Portable open channel flow meter usage requirements

1.The air conductor cable contains a gas pipe and cannot be bent excessively to prevent it from breaking; do not use the air conductor cable as a cable for the flowmeter, and use the air conductor cable to drag the Portable open channel flow meter;

2.The circular ultrasonic transducer in front of the probe cannot be impacted or scratched;

3.The instrument probe should be avoided for a long time in the sun to avoid failure caused by too high temperature;

4.When using an acoustic Doppler flowmeter in places with high sediment concentration, regularly clean the silt on the ultrasonic transducer and pressure sensor to prevent the silt from blocking the pressure sensor.
