WitrynaThe transmitter, manifold, and primary element are received as and assembly. Impulse tubing, root valves, mounting brackets, and interconnections are all eliminated. Units are pre-configured for the application, an especially important fact in light of emerging multivariable technologies. WitrynaPressure transmitters are used in pressure, level, and flow measurement applications. Regardless of application, the transmitter is rarely connected directly to the pipe or vessel. Small diameter tubes or pipes commonly called impulse lines are used to transmit the pressure signal from the process to the transmitter.

Witryna3 lis 2010 · Simply locating the taps between the side and top of the pipe (Answers A, B and C) does not ensure that the impulse tubing will be full of liquid. The impulse tubing between the taps and the differential-pressure transmitter should be sloped so as to allow liquids to fall and exit the impulse tubing into the flow stream. Witryna27 lip 2015 · Cooling elements can extend the maximum process temperature of pressure transmitters from 185 °F (85 °C) up to 392 °F (200 °C). Standoff Piping. Using standoff piping (otherwise known as impulse lines) cools the process before it comes in contact with the pressure transmitter.

Witryna1 wrz 2009 · For such transmitters, the response time of the overall pressure-sensing system from the process to the transmitter output is a strong function of the sensing line’s length and diameter. Table 1. WitrynaIn flow measurement using a primary device such as an orifice plate, a nozzle, or a Venturi meter, impulse lines are used to connect points upstream and downstream (or in the throat) of the meter to a secondary device for measuring the differential pressure.
