  • The microwave barrier is a contactless measuring procedure
  • Can be installed in containers, pipelines, shafts or free-fall sections
  • Range is 0.1 … 25 m
  • If container walls, housings or pipelines are not metal, it is possible to measure from the outside
  • Can also be used under difficult conditions such as high operating temperatures and pressures with the help of a process-adapter
  • The use of microwaves also ensures a high level of insensitivity to any caking on the sensor window

The ProGap S can be easily installed in the following ways:

  • screwing into a G 11/2-inch-screw neck
  • with an DN-40-flange or
  • with a clamp or other mounting

The fitting position of the devices is arbitrary. Important is that transmitter and receiver are positioned precisely to each other. The adjustment is made by means of a counter-screw fitting. Commissioning will be done by evaluation unit.
