Field of application

The Deltabar FMD72 is an electronic differential pressure system used to measure pressure, level, volume, or mass of liquids in pressurized tanks or distillation columns/evaporators. The high pressure sensor (HP) measures the hydrostatic pressure, while the low pressure sensor (LP) measures the head pressure. The level is then calculated in the transmitter using these two digital values. This electronic differential pressure system eliminates the issues associated with traditional differential pressure measurements.

For differential pressure, level, volume or mass measurement of liquids in pressurized tanks and distillation columns/evaporators.

  • Process connections: Threads, flanges and hygienic connections

  • Process temperature: -40 to +125°C (-40 to +257°F), optional 250°C (480°F)

  • Measuring range: 400mbar to +40bar (6 to 600psi)

  • Accuracy: Single sensor up to ±0.05%, system up to ±0.07%

  • International explosion protection certificates, hygienic approvals

Benefits

  • Eliminates traditional mechanical issues resulting in greater process availability and reliability

  • Safety risks are minimized with the new electronic differential pressure system architecture and design

  • Lowest total cost of ownership due to reduced installation time, maintenance, downtime and spare requirements

  • Multivariable level measurement: HART-based differential pressure, head pressure and sensor temperatures from one system

  • Continuous health indication of the entire system via HART-based diagnostic

  • High reproducibility and long-term stability

  • Process safety assured with small flush mounted process connections in hygienic applications
