Sewage flowmeterThere are multiple types, each suitable for different measurement environments and fluid characteristics:

Insertion type Doppler ultrasonic flowmeter: suitable for situations where sewage contains a lot of sediment or bubbles and is in a full pipe state.

Insertion type time difference ultrasonic flowmeter: suitable for situations where the sewage is relatively clear, without too many impurities or bubbles, and in a full pipe state.

The principle of weir type ultrasonic liquid level measurement is applicable to the situation where sewage flows through open ditches, and the flow rate is calculated by measuring the liquid level.

Principle of open channel measurement: using area and velocity methods, simultaneously measuring liquid level and velocity, and then calculating flow rate based on cross-sectional shape, velocity, and liquid level information.

Electromagnetic flowmeter: If the sewage does not pollute or adhere to the electrodes, an electromagnetic flowmeter can also be used for measurement, but it should be used with caution
