Overview

High precision split type ultrasonic open channel flowmeter is used for measuring channel flow by installing a measuring tank weir on the channel. The function of a water measuring weir is to convert the flow rate in the channel into the level of liquid. Measure the liquid level inside the tank with a level gauge, and use a flow converter (secondary meter) to calculate the liquid flow rate based on the liquid level flow relationship of each type of tank.

High precision split type ultrasonic open channel flowmeter Working Principle:

Superfractical acoustic open channel flowmeterWhen used for channel flow measurement, install a water measuring weir on the channel. The function of a water measuring weir is to convert the flow rate in the channel into the level of liquid. Measure the liquid level inside the tank with a level gauge, and use a flow converter (secondary meter) to calculate the liquid flow rate based on the liquid level flow relationship of each type of tank.

The larger the flow in the channel, the higher the liquid level in the trough and weir; The smaller the flow rate, the lower the liquid level. There is no definite correspondence between liquid level and flow rate in general channels. Because the same water depth and flow rate are also related to the cross-sectional area, slope, and roughness of the channel. Installing a weir in a channel, due to the smaller gap or contraction of the weir compared to the cross-sectional area of the channel, the correspondence between the upstream water level and flow rate of the channel mainly depends on the geometric dimensions of the weir. The same weir is placed on different channels, and the same liquid level corresponds to the same flow rate. The weir converts the flow into liquid level.
