Innovative measurement, accurate guarding - Explore the efficient charm of box-type ultrasonic open channel flowmeter

2024/12/23 11:09

In the era of pursuing efficient and accurate water management, accurate measurement of every drop of water is crucial. Today, we are proud to recommend the box-type ultrasonic open channel flowmeter. A collection of high-precision, strong adaptability and intelligent in one of the flow measurement of the new tool.

Our box-type ultrasonic open channel flowmeter adopts the principle of flow rate area method, the flow rate measurement part of the ultrasonic time difference method, through the electronic water ruler to accurately measure the depth of the water, combined with the internal precision processing of the width parameters of the measuring box, to realize the flow rate calculation. The whole process does not depend on the channel parameters, and the calibration is completed before leaving the factory, without the need for on-site calibration, to ensure that the accuracy is worry-free.

Minimization of head loss

Compared with the weir and tank type flowmeter, we use the flow area method, which does not need to change the state of water flow and significantly reduces the head loss, which saves energy and reduces consumption for your project.

Upgraded Measurement Accuracy

Abandon the Doppler point flow rate measurement method, we adopt the time difference method ultrasonic technology, multi-layer cross-layered transducers to accurately capture the average flow rate of each layer of water, effectively reduce the impact of turbulence, improve data stability and accuracy. Especially for the northwestern region with a lot of sediment, the addition of siltation detection function, to ensure that the flow data closer to the real value.
