This type of pressure gauge is used to measure the pressure of liquids and gases in cases where it is inadmissible for the measured medium to enter the measuring device of the pressure gauge. The concept consists in the use of a separating membrane and an inert liquid, which transmits the pressure to the measuring device of the manometer.

• highly viscous liquids
• solid particles, sedimenting sludges
• hot liquids that solidify or crystallize when the temperature drops
• aggressive liquids
• in cases where there are strict requirements for perfect cleaning and sanitation of the system
