Subject to change without notice
A sensor is only activated for measurement when the configured serial number matches
the serial number transferred for the sensor.
If no sensor is detected or a sensor is not functioning correctly, the FLOWSIC500 automati-
cally uses the stored default value (= fixed value) of the state variable.
In this case, the FLOWSIC500 switches to malfunction state and, using the default value,
stores the volume under base conditions calculated for pressure or temperature in the error
volume counter.
If not specified otherwise, the FLOWSIC500 is supplied with the following standard
settings:
2.7.1.1 Integrated pressure and temperature sensors
The FLOWSIC500 with volume conversion and integrated pressure and temperature
sensors does not have any external components. The internal pressure and temperature
sensors are already fitted and calibrated at the factory. The measuring ports are located in
the gas flow meter.
This means the FLOWSIC500 does not require any additional installation of sensors to
determine the measurement conditions and is immediately ready for operation after
volume conversion has been configured.
2.7.1.2 External pressure and temperature sensors
The FLOWSIC500 with volume conversion and external sensors is used at measuring ports
where a test/calibration of the pressure or temperature sensor in the system may be
required.
It is recommended to install a three-way test valve that separates the pressure sensor from
the measurement pressure and provides a test connection to test the pressure sensor.

tures to -25°C.
