Area flow rate/flowmeter

Area flow meter can monitor the flow of open channels, partially sewage filled pipes, and overflow pipelines without sinks or weirs. *Suitable for flow monitoring of municipal water, mixed water, untreated sewage, and irrigation water. The streamlined ultrasonic sensor utilizes an immersed ultrasonic sensor to continuously measure the flow velocity and liquid level in the channel. The electrode does not scale and is corrosion-resistant. Can be installed in turbulent and fast currents.
