2. Installation
The installation of the differential pressure gauge is made following the installation
recommendations for pressure gauges according to EN 837-2 /7.
T
Prior to the installation of the pressure gauge, the pipes should be thoroughly cleaned.
T
The pressure gauge should be installed and operated such as to avoid exposure to
vibration.
Requires mounting by means
T
The pressure gauges should be protected against contamination and high temperature
fluctuations.
T
The permissible maximum media/ambient temperature must not be exceeded.
