HART

Your benefits

The electronic differential pressure measurement system eliminates issues of  traditional differential pressure measurements using impulse lines or  capillaries:

• Eliminate measurement drift due to ambient temperature changes

• Eliminate line condensation or evaporation events (dry/wet leg  inconsistencies) and plugging events

• No high cost of heating impulse lines to prevent freezing (installation,  energy)

• Eliminate tubing and connection leaks often seen with traditional systems

• M*riable 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

• Intuitive menu-driven installation

• Color-coded wiring

• High reproducibility and long-term stability

• High reference accuracy of individual sensors:
  up to ±0.075 %,

  as PLATINUM version: ±0.05 %

• Increased process availability and reliability

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

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

The Deltabar FMD72 is used to measure the level, volume or mass of liquids in  pressurized tanks. The system compromises two sensor modules and one  transmitter. One sensor module measures the hydrostatic pressure (high pressure)  ａnd the other one the head pressure (low pressure). The level (electronic  differential pressure) is calculated in the transmitter using these two digital  values.
