Measuring system and pressure chamber of DA12 are available in different suitable material, to suit application and installation requirements.

DZ13/14 – three and four-spindle shut-off and equalizing valves are also available as accessory, which are especially suited for mounting differential pressure instruments. Eg. they are used for:

  • Depressurizing or shutting down of plant
  • Cutting differential pressure instruments off a plant to enable controlling or repairing
  • Shut-off valves may be used for operational checks on site.

Working Principle:

Differential pressure instrument works on principle of movement of rugged and sensitive diaphragm. The pressure or differential pressure to be measured creates an unbalanced forces of diaphragm springs for measuring range until new balance is reached.
