6. INSTALLATION
6.1. General recommendations
It is recommended that in case of a gaseous medium, the transmitters should be installed
above the measuring point so that condensate may flow to the point from which the meas-
ured pressure is collected, while in case of liquid medium or steam, it should be installed
below the point of pressure intake. The configuration of impulse tubes and valve connection
system should be selected taking into account the measurement conditions.
Differential pressure transmitters for gases PRE-50G should be obligatorily installed verti-
cally.
6.1.1. Installation instructions for transmitters with separators
The protection of the separator diaphragm can only be removed shortly before installation.
Hydrostatic pressure of the manometric liquid column in the transmitter-separator system may cause
incorrect indication of the measured value. After installation, the transmitter must be pressure-reset.
Do not clean or touch separator diaphragms using hard or pointy objects.
Separators with pressure transmitter form a closed, calibrated system filled with gauge
fluid. The opening for filling the device with gauge fluid is sealed and must not be opened.
When choosing a mounting location, it is necessary to ensure sufficient stress relief of the
capillaries tension in order to avoid excessive bending.
Incorrect installation of the sealing may result in incorrect measurement indications.
Special attention must be paid when selecting correct dimensions of the sealing.
As standard, the separators are not provided with the gaskets.
