Establishing Pressure
Gauge Pressures
Pressure should be admitted slowly into the gauge, preferably through a metering valve.
It is very convenient to have a volume adjusting pump such as RUSKA Series 3990
Manual Pressure Control Packs to adjust the system pressure. The RUSKA Series 3990
Manual Pressure Control Packs provides a supply gas regulator, valves, monitor gauge,
and system volume adjuster all integrated into a compact package. The RUSKA Series
3990 Manual Pressure Control Packs facilitates the control of the input pressure to the
gauge and provides facility to change the float position.
The index mark for the plane of reference on the RUSKA 2470 base is a circumferential
groove around the base of the column. This reference is compared to the bottom face of
the hanger mass as shown in Figure 5-16.
