Prevent cross talk in one of the following ways:
● Mount sensors on separate frames
● Decouple the pipeline using flexible tube or couplings
High risk of cross talk when using non-flexible pipes
Low risk of cross talk when using flexible pipes and separate frames

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.
