4.16 Before commission-
ing Before installing the sensor read the maximum operating pressure (PN) on the sensor label. The
operating pressure indicates the pressure to which the measuring pipe and connections have
been designed for. The sensor has passed pressure tests of this value or greater. This, is not
the case with the sensor enclosure (i.e. the enclosure covering the measuring pipe). If for some
reason the measuring pipe fractures, a pressure will be generated in the enclosure.
The burst pressure for the CMF - B through F enclosure is approximately 725 psi (50 bar) and
approximately 1000 psi (70 bar) forCMF - A.
The pressure values are only approximate and therefore cannot be taken as an absolute value
indicating when a possible fracture or leakage will occur.
When working with operating pressures/media which may cause pipe fractures and possible
injuries to people, equipment or anything else, special precautions are recommended to be taken
when building-in the sensor i.e. special placement, shielding, pressure release valve or similar.
The sensor enclosure is supplied with a 1/8" nipple. When the nipple is removed a pressure
release valve can be connected to automatically shut off the flow to the sensor in case of leakage.
For instructions on the mounting, please refer to the section "Mounting of pressure release valve".
Warning
Important
Before removing the nipple from the sensor enclosure, note the following:
Penetration of humidity, liquid or particles into the sensor must be avoided as it may influence the
measurement and in worst case affect the measuring function. This, can be avoided when
following the procedure below:
1. Place the sensor in a dry, clean place leaving it to settle until it reaches ambient temperature,
approximately 68° F (20 °C).
2. Be careful when disconnecting the nipple and mounting the pressure release valve.
3. Check that the pressure release valve has been correctly mounted and thoroughly tightened
so that the sealing ring fits tightly. Always replace old sealing rings with new ones after each
removal.
