Details

 

Radar level meters with guided waVe (principle TDR)
• Suited to continuous level mesurement of various liquid, bulk solids, mush and pasty materials.
• Quick view measured values on the display
• Universal use, direct mounting into hoppers, silos, tanks, sumps etc.
• Variants with stainless steel rod or rope electrode
• Measuring range up to 40m
• Possibility of using in explosive areas (version Xi, XiT), or in flammable dust areas (Xd, XdT)
• Current output (4 ... 20 mA), HART ® protocol

The GRLM ® radar level meters are compact measurement devices including an transmitter of microwave pulses, central processor unit and display module. The electronics transmits very short electrical pulses (0.5 ns), which are linked to a one-wire transmission line (measuring electrode). Measuring electrode can be created of rod or rope. The pulse propagates along the electrode in the form of electromagnetic wave toward the level surface, where it is partly reflected and the reflected component is returned to the receiving module of the electronics. The electronics measures the time of flight of electromagnetic wave and the instant distance to the surface level is calculated. According to the level height, the level meter output is set and the measured value is displayed on the display.

Radar level meters are resistant against changes in the atmosphere (pressure, temperature, dust, steam) and to changes in medium parameters (change in dielectric constant, conductivity).
