Hydrostatic testing
The flowmeter is pressure-tested before delivery to 1.5 times the rated working pressure of the
sensor.
• In the case of process connections pressure-rated less than 100 bar, the connection is the
limiting component.
• In the case of process connections pressure-rated above 100 bar (stainless steel sensors) or
above 160 bar (Hastelloy sensors), the sensor is the limiting component.
In all cases the maximum allowed hydrostatic test pressure (MATP) of the flowmeter is 1.5 times
the marked MAWP (PS) at 20 °C.
Pressure test of a completed flow system with piping and other components can be done at
pressures no higher than 1.5 times the marked MAWP (PS) at 20 °C of the lowest rated system
component.

Mounting a pressure guard
Pressure guard selection
Siemens does not supply the components of the pressure guard solution because the
arrangement and components are closely related to individual safety and protection practices in
each place.
The selection of pressure guard solution is the responsibility of the user, however Siemens
recommends the following forms of pressure guard:
• A pressure switch screwed directly or piped into one of the purge ports and connected to an
automatic shut-off valve will disable pressurized supply to the meter.
• A relief valve or bursting disc screwed directly or piped to one of the purge ports to carry any
spilt fluid to drain after opening.
