Pitot tube NPL type (L / straight)

PRESENTATION KIMO offers a broad range of Pitot tubes of great quality and accuracy realised according to the NF X 10-112 norm.

The KIMO Pitot tubes, connected to a differential column of liquid manometer, with needle or electronic, enable to measure the dynamic pression of a fluid in movement in a pipe and determine its speed in m/s and its flow in m3/h.

The Pitot tubes are used in climatic engineering, ventilation, dust-removal With built-in temperature probe and pneumatic transport. They are Pitot tube straight type Pitot tube L type with particularly adapted for measurement Pitot tube L type and straight type with K TC in warm air, charged with particles and Pitot tubes with ellipsoidal top.

The Pitot tube is introduced perpendicularly in the pipe by pre-determined points (cf. ''Measurement''). The antenna composed of an ellipsoidal nose (bow) maintained in parallel and in front of the flow to control. The total pressure (+) is picked up by the bow and is connected to the + sign of the manometer. The static pressure (-) picked up by the small holes located around the antenna is connected to the – sign of the manometer. The connecting cable of the K thermocouple is connected to the input K of the manometer (for the Pitot tube type L with K TC).

The device then indicates the dynamic pressure, sometimes called speed pressure. The dynamic pressure corresponds to the difference between total pressure and static pressure : Dp = Tp-Sp

APPLICATION

Total pressure (Tp) Static pressure (Sp)

Dynamic pressure = Tp - Sp

Example above :

The Kimo manometer (portable or transmitter) directly indicates the speed in m/s.
