Hydrostatic Level Transmitter MEMPRO Ex C

The MEMPRO Ex C measuring instrument operates in accordance with the Pitot static principles, i.e. the level signal is proportional to the hydrostatic pressure in a measuring tube plunged into the liquid. It is used for measuring fill-levels of flammable liquids.

The device is approved for use in danger zone 0 for flammable media assigned to explosion group IIC. The MEMPRO Ex C fill-level transmitter is used as a passive 2-pole device in intrinsically safe circuits. It converts the backpressure signal into a load independent current within a range of 4 to 20 mA.


  • Fill level monitoring in ATEX Ex area
  • For flammable liquids
  • No moving parts
  • Accurate and reliable measurement
  • Output signal 4-20 mA, 2 wires
  • Free from fluid viscosity or conductivity
  • Scales: up to 4000 mm
  • ATEX certification


For measuring the fill level of tank (atmospheric pressure) with an Ex area requirement. The device is suitable for flammable liquids and for use in ATEX Ex area (see the agreements herein after). The sensor (ceramic) is in contact with the vapours not directly with the fluid.
