Values for PV, SV, TV, QV
The following values can be assigned. PV is used for the analog output.
1
Volumetric flow, a. c. (default PV)
2
Volumetric flow s. c. (default SV)
3
Pressure
4
Temperature
5
Velocity of sound (Default QV)
6
Velocity of gas (Default TV)
7
Methane content
2.4.3
RS485 interface (passive, option)
The optional RS485 interface supports the following protocols:
● Modbus ASCII
● Modbus RTU
The RS485 serial interface allows full access to measurement values and diagnostic data
via serial communication. Access can also be realized from remote.
The RS485 serial interface must be externally powered. For electrical connection please
refer to

Wet gas detection
The FLOWSIC30 firmware has a diagnostic feature for detection of wet gas inside the meter
(wet gas detection, patent pending).
The wet gas detection uses real-time monitoring of multiple diagnostic parameters of the
FLOWSIC30 in order to identify wet gas conditions (liquids in the gas stream such as liquid
hydrocarbons, water and oil). Liquids in the gas stream are usually undesired in the gas
production process and may require appropriate actions such as process optimization or
consideration for meter readings.
The wet gas detection typically detects wet gas with more than 0.5 % LVF (Liquid Volume
Fraction).
For detailed information, please refer to the document “Short manual HART
®
compatible interface FLOWSIC30”.
For details about Modbus communication, refer to “Short manual Modbus
FLOWSIC30”.
Since the wet gas detection uses common standard diagnostic meter
parameters, the wet gas warning may be activated in parallel to other user
warnings. In this case, a thorough analysis of the operating and process
conditions may be beneficial to find the root cause. Contact SICK Customer
Service should you require technical support.
