If the tail pipe is not sufficiently rigid to accept the wight of the pressure gauge, particularly where vibration
exists, the gauge should be mounted by means of a mounting device for surface or pipe mounting, if neces-
sary with capillary extension.
The pressure gauge should be installed such as to avoid that the admissible ambient temperature (ambient
and medium) and possibly convection and heat radiation will not exceed the temperature span the pressure
gauge is intended for. Suitably shaped tail pipes or syphons with water filling may be used to separate the
gauge and its device from hot pressure media.
Should the measuring media be subject to rapid fluctuations in pressure, or pressure surges have to be
taken into account, these must not be allowed to act on the pressure element. The pressure surges must be
restricted in their effect, for example by filling integral restrictor screws (to reduce the cross-section in the
canal) or by using an adjustable snubber device.
Normal gauge position will have the dial facia in its vertical position. Positions other than vertical will be
indicated by a symbol on the dial.
No pressure higher than indicated by the working pressure symbol (final value) on the dial must be
applied to the pressure gauge during hydrostatic pressure test of the system. Otherwise the pressure
gauge must be isolated or removed during this operation.
Before removing the pressure gauge, the measuring element must be depressurised.
The straining screws of the upper and lower flange must not be loosened.
To avoid damages the pressure gauge have to be stored in its original packing.
Storage temperature -40 to +70°C.
