8188 Guided Microwave Level Measurement Device
Brand: Burkert Fluid Control Systems
The Type 8188 is a level measurement device with cable, rod, both interchangeable probe or with coax probe, designed for continuous level measurement. The unit is suitable for liquids, for industrial use in all areas of process technology.
With a measuring range up to 75 meters, the 8188 is best suited for tall vessels. Even process conditions such as strong steam generation, density fluctuations or changes of the dielectric constant do not influence the accuracy of the measurement. Build-up or condensation on the probe or vessel wall do not influence the measuring result.
A liquid interface measurement is also possible with the Type 8188, typically an oil/ water interface.
