This liquid seperator can be used up to 2000 bar.
The separator can be used in a calibration system with two different types of oil. The first oil is used in the deadweight tester and the secound is used in the device under test.
The liquid seperator does not have a physical barrier, but uses a mixing chamber with a lower and upper pressure port. The lower pressure port is dedicated to be connected to the process oil which has a higher density than the oil used in the deadweight tester. The upper pressure port is used for connecting the deadweight tester.
