Level Measurement & Control


Measurement certainty for bulk solids

February 2013 Level Measurement & Control

Bopp & Reuther Messtechnik’s MG1 series uses TDR (Time Domain Reflectometry) technology. Energy optimised, high-frequency electromagnetic impulses, generated by the electronics, are propagated along the probe. When these impulses hit the surface of the media, part of the impulse energy is reflected back up the probe to the electronics. The level is calculated from the time difference between the impulse sent and the impulses reflected. The sensor can output the analysed level as a continuous measurement reading through its current output, and it can convert the value into a switching output signal. Some of the special advantages are:

* Fast reaction time of 0,5 sec.

* Precise continuous level measurement and reliable point level detection combined in one device.

* Suitable for liquids as well as powdery solids.

* No influences caused by tank/vessel internals.

The innovative technology enables direct, precise and highly reliable continuous level measurement as well as point level detection in liquids and solids, independent of changing process conditions (such as density, conductivity, temperature, pressure, vapour and turbulence). It is suitable for all types of process and storage tank applications and has an exceptional performance in media with low dielectric constant (ie, low reflectivity) such as oils and hydrocarbons.
