Tabung Pitot

When a pitot tube is used as an integral part of a flow control valve control circuit, it provides the differential pressure (∆P) to power the flow control pilot. A pitot tube flow sensor is recommended for applications where low head loss is essential and required flow is relatively high.
Due to its low ∆P output, a flow control valve with pitot tube (Model 770-j) should employ a high sensitivity pilot.
