Comments No. 33: Why we require pressure gauge on each receiver? Do you want vacuum gauge for this receiver?
RE JST 8-12-2015: Experience in Europe is that receivers are emptied during trials. For emptying the receiver needs to be pressurized and brought back to vacuum again during the trial. Pressure gauges are needed to make sure that the receiver is vacuum before it’s reconnected to the process again.
TFS Reply: We never used the pressure gauge for this procedure during trial. These receiver capacities are very small.
RE JST 10-12-2015: We see significant differences between local pressure and vacuum pressure measurement in Scada. The local pressure measurement is used to adjust the pressure in the system, it is an indication if the header is dry (it has been experienced in the past that the header was not dry).
