The electronic differential pressure system Deltabar FMD-72 from Endress+Hauser consists of a transmitter and two sensor modules. The transmitter calculates the pressure difference from both sensors and transmits the level, volume or mass to the controller via 4 to 20 mA. By dispensing with capillaries or impulse lines, the level measurement is very reliable and has a high level of accuracy and reproducibility, according to the supplier. Without impulse lines and additional connection points, measurement problems due to icing, clogging or condensation do not occur. Typical applications for the differential pressure transmitter are level applications in storage or buffer tanks, reactors and distillation columns.
