SSEA Schmierer South East Asia Guided Wave Radar

Guided Wave Radar

Guided wave radar (‘radar on a rope’) transmitters are used for reliable product level monitoring. This level measurement technology is not impacted by dust, vacuum, humidity, foam, pressure changes, dielectric and temperature.

The GWR is installed on top of the tank.  A probe or cable is lowered into the vessel from the top and continuously measures the level of the product as it makes contact along its length. A microwave signal is transmitted from top to bottom and reflected back. The distance is calculated by the speed of light and the time delay.

Different probes are used for a variety of applications:

  • coaxial probes for liquids with low dielectric constants
  • single element probes for viscous products
  • twin element probes for long measurement

Interface measurement is possible if the 2 media have different dielectric constants.

GWRs are also used as combo units with Magnetic level gauges for all kinds of liquids in vessels and tanks to have a backup for power cuts or in the power start up process.

SSEA Schmierer South East Asia Non Contact Radar

Non Contact Radar

The Radar Level Meters are excellent devices for no contact level measurement. The microwave
impulses, emitted by the radar’s antenna, travel at speed of light and a part of their energy, reflected by the surface of the medium to be measured, is received by the same antenna.The period of time (flying time)
between the emission and the arrival of the impulses, is proportional to the existing distance between the antenna and the surface of the medium to be measured.
