Flow Meter Portable Open Channel Flow Meter

Short Description:

◆The working principle of the open channel weir and groove flowmeter is to set a standard water weir groove in the open channel, so that the flow rate of the water flowing through the weir groove is in a single value relationship with the water level, and the water level is measured according to the specified position, and calculated by the corresponding formula flow.
◆According to the principle, the accuracy of the water flow measured by the flow meter, in addition to the need for a standardized water weir tank on site, the flow rate is only related to the water level height.
◆The accuracy of the water level is the key to the flow detection.
◆We use The liquid level gauge is a high-quality ultrasonic open channel level gauge. This level gauge can meet the needs of on-site measurement in terms of data accuracy and product anti-interference and corrosion resistance.
