Pitot Tube Flow Sensor PRP

The PRP Pitot Tube Flow Sensor from Aplisens uses the differential pressure principle based on the basics of Bernoulli. A rectangular design of the PRP sensor profile is divided diagonally into two symmetrically constructed chambers with sensing holes (dp-tappings). The chamber facing to the upstream generate a higher pressure (p+) and the chamber in the downstream a lower pressure (p-). Several dp-tappings along the ensor profile provide a steady averaging of the flow velocity. This facilitates exact metering even with irregular flow profiles. Each chamber is connected to the corresponding side of a differential pressure transmitter. The value of the differential pressure is the measure to determine the flow. With increasing flow the dp increases. A differential transmitter converts the dp into an electrical signal (i.e. 4-20mA) that is transmitted to the process control system.
