5.2. Connection to the system
-
After installation, RSE must be connected to the system. Before connection, make sure that at least the portion of the plant
upstream of the meter is sectioned and that, therefore, there cannot be any flow of gas during the installation;
-
Before connection, make sure that the maximum system pressure is lower than the maximum pressure set for the meter,
which is fixed and equal to 0.5 relative bar;
-
If necessary, use fittings (not supplied) to connect RSE to the piping.
-
During the tightening of the fittings, do not exceed the torque of 110Nm;
-
RSE operates only in vertical position;
-
RSE is provided with an on/off valve in the "open" status; therefore, it is ready to deliver and measure.
-
Verify that the utilities on the customer side are closed.
-
Slowly load the RSE meter with pressure.
-
If on the meter a piping for pressure measurement has been subsequently installed, check the tightness of the related
connection.
-
After leak testing, slowly remove pressure to the RSE meter.
Once the tightness has been checked, the meter is ready for use.
The meters of the company SAMGAS require no maintenance.
WARNING
When the meter is disassembled, it may contain a residual amount of gas. Considering the danger of explosion, it is necessary to take
safety measures, e.g.:
–
After disassembling the RSE meter, clean it very well with an inert gas.
–
For transporting the meter with residual amounts of gas, use a vehicle with an open or vented loading area.
5.2.1. Using the ZVEI probe
The ZVEI probe (available as an option) is equipped with magnetic coupling. Place the probe in the provided groove on the front part of
RSE with the cable facing downwards. The magnet and the groove will retain the probe in place.
To enable the communication on the ZVEI optical port, it is sufficient to let the display show the SD menu.
