WitrynaOrifice plates are most commonly used to measure flow rates in pipes, when the fluid is single-phase (rather than being a mixture of gases and liquids, or of liquids and solids) and well-mixed, the flow is continuous rather than pulsating, the fluid occupies the entire pipe (precluding silt or trapped gas), the flow profile is even and … Witryna27 maj 2014 · tapping a liquid stream A vertical pipeline flowing upward often is the best location for a liquid sampling nozzle because you can be sure the pipe is full. For this setup, both the horizontal and inclined nozzles shown in Figure 5 are acceptable — but, whenever possible, opt for the horizontal nozzle as it allows a shorter probe that’s ...
WitrynaFor liquid flows, it is important that no gas bubbles collect in the impulse lines, or else those bubbles may displace liquid from the lines and thereby cause unequal vertical … Witryna26 wrz 2010 · For example, when a single 90-degree elbow precedes an orifice plate, the straight-pipe requirement ranges from six to 20 pipe diameters as the beta ratio …
Witryna26 wrz 2010 · The size and orientation of the impulse-line pressure taps depend on both the pipe size and the process fluid. The recommended maximum diameters of pressure-tap holes through the pipe or flange are: ¼ inch for pipes under two inches in diameter; 3⁄8 inch for two- and three-inch diameter pipes; ½ for four- to eight-inch …
WitrynaFor liquid services, taps orientation shall be horizontal or up to 45° below the horizontal, in order to allow the trapped vapour to exit the impulse lines. The taps orientation shall not be more than 45° below the horizontal, to avoid entering of sediment into impulse line. melissa from the socialWitryna3 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.
