The device is used for the following measuring tasks:

  • Flow measurement (volume flow or mass flow) in conjunction with differential pressure sensors in gases, vapors and liquids
  • Level, volume or mass measurements in liquids
  • High process temperatures up to 400 C (752 F) possible with diaphragm seal mount
Your benefits
  • Very good reproducibility and long-term stability
  • High reference accuracy up to 0.035 %
  • Turn down up to 100:1, higher on request
  • Used for flow and differential pressure monitoring up to SIL3, certified to IEC 61508 by TV SD
  • High level of safety during operation thanks to function monitoring from the measuring cell to the electronics
  • The patented TempC membrane for the diaphragm seal reduces measured errors caused by environmental and process temperature influences to a minimum
  • Easy electronic replacement guaranteed with HistoROM/M-DAT
  • Uniform platform for differential pressure, hydrostatics and pressure (Deltabar S Deltapilot S Cerabar S)
  • Practical user navigation for quick and easy commissioning
  • Extensive diagnostic functions
  • Cost-effective installation with Deltabar S FMD77, capillary on low-pressure side
Measuring Principle

The process isolating diaphragms are deflected on both sides by the acting pressures. A filling oil transfers the pressure to a resistance bridge (semiconductor technology). The change in the bridge output voltage, which depends on the differential pressure, is measured and processed

  • Standard operating pressures: 160 bar (2 400 psi) and 420 bar (6 300 psi)
  • High long-term stability
  • Very high single-sided overload resistance
