4.2.2 Pressure relief valve
Pressure Reduction Valve. The pressure values are approximations. An exact specification of
the absolute value at which a rupture or leak occurs is not possible. For operating
pressures/fluids, which could possibly cause a meter pipe rupture with resultant personnel
injury, property damage, etc. special protective measures for the sensor installation are
recommended (special arrangements, protection covers, pressure relief valves etc.).
The sensor housing incorporates a 1/8“-nipple. When the nipple is removed, a pressure relief
valve can be installed to automatically block the flow to the sensor in the event of a leak.
Important
Before removing the nipple from the sensor housing the following must be considered:
Under no circumstances may humidity, liquids or foreign objects enter the flowmeter primary
housing because the measurement accuracy could be adversely affected.
This type of problem can be avoided by observing the following instruction:
1.
To acclimate the sensor it should be placed in a dry, clean area until it has reached an
ambient temperature of approx. 20 °C (68 °F).
2.
Care should be exercised when removing the nipple and installing the pressure relief valve.
3.
Ensure that the pressure relief valve is correctly installed and properly tightened, so the
gasket is seated correctly. Whenever it is removed the gaskets should be replaced.
