Pressure & Vacuum gauges

Products

Pressure gauges are used in chlorine gas line supply for monitoring the chlorine gas pressure in chlorine tanks and cylinders.  While container or cylinder is discharging, the pressure is dropping, therefore pressure gauges are used to check the fullness of     container or cylinder.

Vacuum gauges  are used in chlorine gas line supply between vacuum regulator and ejector. They monitor the vacuum in ejector and in the vacuum line.  A constant vacuum ensures safety and reliable operation.

GENERAL

Pressure gauges are used in chlorine gas line supply for monitoring the chlorine gas pressure in chlorine tanks and cylinders.  While container or cylinder is discharging, the pressure is dropping, therefore pressure gauges are used to check the fullness of     container or cylinder.

It is important to consider that the pressure also depends on the surrounding temperature. For example at 20 ˚C pressure is 5.8bar, while at 40 ˚C is 10,5bar.

Vacuum gauges  are used in chlorine gas line supply between vacuum regulator and ejector. They monitor the vacuum in ejector and in the vacuum line.  A constant vacuum ensures safety and reliable operation.
