Frequency Control for VFD, VSD for pump motor control by Fischer DE38 Differential Pressure Transmitter

For control of hydraulic fluids, oil, lubricants Fischer DE38 Differential Pressure  Transmitter is widely used. Differential Pressure measurement in hydraulic fluid pipe lines is an important technology in measurement of fluid flow and there by volume measurement and control. Fischer DE38 Differential Pressure Transmitter measures the pressure differential between two points and thereby calculates the flow rates of the fluids and volume of the fluids. This technology helps the user in finding out the consumption of hydraulic fluid oil and lubricants and there by reduce operational cost, maintenance cost.


  • Monitoring of compressors, filters and vacuum systems
  • Measurement of differential pressure between supply and return fuel lines in heating systems
  • Flow, control-pressure and level measurement
