There are many varieties of ultrasonic open channel flowmeters, and two common types are weir open channel flowmeters and trough open channel flowmeters. It can be used as a flow meter for measuring free surface natural flow in non-full tubular open channels. The water path that is not full of pipes is called an open channel, and the one that measures the flow of water in the open channel is called an open channel flowmeter. In addition to circular, ultrasonic open channel flow meters also have various shapes such as V-shaped, trapezoidal, and rectangular.
The main component of the ultrasonic open channel flowmeter is the Parshall groove (also known as the Babbler groove), which is an auxiliary device for open channel flow measurement. When the instrument is working, the sensor is not in contact with the measured fluid, which avoids contamination and corrosion of sewage in the channel. Used to measure the amount of sewage, it can be more reliable than other forms of meters. The optional RS485 serial port of this instrument can be connected to a computer or other data collectors, and can also be connected to a wireless communication module to realize wired or wireless remote communication.
