Siemens Differential Pressure Transmitter Calculations (Flange Type)

Siemens Pressure transmitters / differential pressure Transmitters, for flange type (Without remote seal)

The Transmitter Lower Range Value (LRV) and Upper Range Value (URV) calculations for a siemens pressure/differential pressure transmitters.

The following figures showing calculation formulae for different measurements like level, separation (interface), and density measurements for both Open & Closed Tanks using Flange Type Pressure/Differential Pressure Transmitters.

In below figures : PMA & PME are nothing but LRV & URV of a transmitter.

Separation Layer Level Measurement

Open Tank Density Measurement using Pressure Transmitter

Notes
  • For the separation layer (interface level) measurement, the separation layer has to be positioned between the two spigots. Also you must make sure that the level in the container is always above the top spigot.
  • When measuring density, make sure that the level of the medium remains constant. The level should be above the top spigot
