pressure tap

pressure tap

[′presh·ər ‚tap]
(engineering)
A small perpendicular hole in the wall of a pressurized, fluid-containing pipe or vessel; used for connection of pressure-sensitive elements for the measurement of static pressures. Also known as piezometer opening; static pressure tap.

- the pipes of the circuit, - 2 motor pumps with their hydraulic circuit: - pipes, 3/8 - an aspiration provided with a padlockable valve, - a valve preventing the return of oil to the pumps, - a manometer equipped with a pressure tap and a padlockable isolation valve (indicates the pressure of the pump in service).

Figure 21 shows that no appreciable trend exists between the stationary and moving ground [delta]Cp values, Figures 22 and 23 show the surface pressure tap locations referenced.
Estimated errors are in measured pressure associated with the different pressure tap geometries.
where p(x, z) is the averaged pressure measured at each pressure tap on the model surface (x and z stand for the pressure tap coordinates in a reference frame indicated in Figure 1; see also Table 1).
When the impeller was pumping upward the fluid velocities near the pressure tap increased thus reducing the pressure readings as the impeller speed was increased.
The cost of Strip Tube is $10/m, so it is much cheaper than the conventional pressure tap method.
These meters have no downstream and shorter upstream straight pipe requirements for standard accuracy, have lower head-loss, and are less susceptible to blockages and plugging as the annular chamber was replaced with a single pressure tap. They are more accurate than most other meters as typical head-loss percentages for modified short form meters range from 3.0 to 10.0 per cent of differential depending on Beta ratio selected.
Figure 2 shows a single chamber orifice meter with a downstream pressure tap and an extra DP transmitter.
As mentioned, the conventional pressure tap approach provides good information.
Since the distance between this y-section and the first pressure tap is around 1.87 m, then a fully developed flow can be achieved easily before taking measurements.
The problems of centering the plate, alignment of the inlet and outlet piping, and pressure tap to plate dimensions have also been solved using standard fittings and patented plate holder designs.
