● Gas applications
Vapor condensation or oil traces in the gas may result in erroneous measurements.
– Do not install the flowmeter at the lowest point of the system
– Install a filter.

Flow direction
The calibrated flow direction is indicated by the arrow on the sensor. Flow in this direction will be indicated as positive by
default. The sensitivity and accuracy of the sensor is identical with reverse flow.
The indicated flow direction (positive/ negative) is configurable.
CAUTION
The sensor must always be completely filled with process media in order to measure accurately.
Orienting the sensor
SITRANS FCS400 operates in any orientation, but Siemens recommends orienting the sensor in one of the following ways:
1. Vertical installation with an upwards flow (self-draining)
