NettetInstrument elevation in relation to higher and lower tapping points; at high operating pressures, zero compensation for gas phase weight/density. 3. Process connection with no diaphragm. Differential pressure transmitters with no remote capillaries seals should have their location as follows: keep the impulse tubing as short as possible NettetThis tapping point must have a larger bore than the Impulse line and probably the most convenient size would be a 3/8” impulse line leading into a 1” tapping point. If you head to 1 ½”, 2” or even larger diameter tapping points, you need larger diameter and heavier isolation valves and stronger nozzles, all of this a lot more expensive. Nettet12. mar. 2003 · Jul 30, 2002. #1. Hi List! I'm looking for a standard/technical reference for instrument tapping point considerations such as selecting the right stub (for connection of NPT thermowell or primary valves), material of impulse piping, type of primary and secondray valves etc. thanks in advance.
