Effusion method: vapour pressure balance (7

A pressure balance (5) is associated with the control valve and enables the decrease in pressure to remain constant irrespective of load pressure by means of the measuring diaphragm.

The adjustment of the input pressure balance takes place as a function of one of the load pressures of the consumer or of a power beyond consumer.

According to the invention, a lower load pressure is applied to the pump when the pressure balance is opened fully, whereby the decrease in pressure is attenuated by the measuring diaphragm.

Pressure balances (dead-weight testers) are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments.

Pressure standards (dead-weight testers) are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments.

Due to the shape of the preforms, the bottles can be bottled.

The plunger (17) works as a pressure regulator, the difference in pressure when the pump speed is increasing being used as the control parameter for the amount pumped away.

The consumers are supplied with pressure medium via a load-independent flow division (LIFD) orifice gauge (14) and an LIFD pressure scale (16).
