Technical Field

Background
The ultrasonic open channel flowmeter measures the water level by using an ultrasonic echo ranging principle, converts a water level signal into a flow signal by an operation unit in an instrument host, and measures the water level flowing through a weir notch by installing a standard water gaging weir notch in an open channel and arranging an ultrasonic liquid level meter at a specified position, and brings the water level value into a specified flow formula or an empirical formula to calculate the liquid flow.
The principle of the ultrasonic open channel flow meter is that when ultrasonic waves propagate in a flowing medium, the ultrasonic waves carry flow velocity information of fluid, the flow velocity of the fluid is obtained by analyzing and processing the ultrasonic waves, and then the flow is calculated. The flow velocity distribution of the fluid in the open channel is uneven, and the ultrasonic wave is influenced by factors such as noise, silt, water depth, channel wall roughness and the like when being transmitted in the fluid, so that the flow meter has low measurement precision and poor stability under the condition of few sound channels.
