Measuring assemblies
The preferred measuring assemblies for various possible applica ons are
speci ied in DIN 19216. f
The following schema c diagram shows a recommended assembly for liquid
media. As thro ling devices, dif eren al pressure transducers should be provided
in accordance with DIN 1952 (issue 07.82), now replaced by EN 5167/1.
The dif eren al pressure lines must be made from metal, their bore must not f
be less than 4 mm and the efec ve length between the valve manifold and the
dif eren al pressure gauge must be at least 500 mm. f
In addi on, the length and the bore of
the pressure lines should be such that,
with cold lines, the response me of
the pressure gauge is not more than
5 seconds.
The connec ons of the dif eren al
pressure lines must be welded, brazed or
screwed using metal sealing elements.
Shut-of valves in dif eren al pressure f
lines must only be operated using tools.
