ABSTRACT:
In order to enable measurement of liquid flow through channels noninvasively without contact or interference with the flow through the channel, detectors of liquid level and velocity through the channel are installed above and below the channel and transmit and receive only ultrasonic signals. A flow measuring system is operated by their detectors and measures flow in terms of the product of the area through which the liquid flows and its velocity.
