2 Installation
2.1 Installation
The transmitter can be installed above or below the pressure tapping point.
When measuring gases we recommend installing the transmitter above the pressure tapping point and
laying the pressure pipe with a constant downward gradient to the pressure tapping point so that
condensation which forms can drain into the main pipe and the measured value is not falsified.
When measuring liquids the transmitter should be installed below the pressure tapping point and the
pressure pipe should have a constant upward gradient so that entrapped gas can escape into the main
pipe.
The installation point should have good access, if possible in the vicinity of the measuring point and should
not be exposed to strong vibration. The permissible ambient temperature limits should not be exceeded.
The transmitter should be protected against direct heat.
The operating data must be compared with the values specified on the rating plate before installation.
The housing must be kept closed during assembly!
