Primary flow element. A primary flow element is the element of a flow meter that serves to indicate the quantity or velocity of flow. For example, in the case of an orifice flow meter, the differential pressure across the orifice plate is the primary flow element.
First, an area velocity flowmeter is one of the few flowmeters that will measure flow in a partially filled pipe or channel. This is perfect for gravity flow systems with possible solids in the water. The AVM can be easily installed in the pipe at a manhole or even at the final discharge point.
