The connection between the diaphragm and the measuring instrument is carried out using special equipment; therefore, it is not possible to screw the diaphragm onto the instrument alone.

The diaphragm (in combination with the pressure gauge) must be filled with an incompressible liquid that transmits the pressure of the medium through the diaphragm to the measuring instrument. The liquid must be clean and free of bubbles.

During filling, it is important to ensure that no air bubbles remain between the diaphragm and the measuring instrument, as they could affect the accuracy of the measurement.
