Level measurement technology and devices for safety at tanks and silos provided by MOLLET Füllstandtechnik.


The devices of the MOLOSwave series for continuous level measurement are working with the Time Domain Reflectometry (TDR) measurement principle. They are specifically designed for the use in bulk goods. During the measurement high frequency microwave pulses with low energy are coupled onto the probe and guided along this probe to the bulk goods. The product surface partly reflects these pulses. The electronic detects the reflected pulses and calculates the actual filling level from the time difference of the transmitted and received signals. These filling levels are made available as a 4-20 mA signal for further signal processing. This signal can be visualized with easy to use and well legible indicating units that are mounted in a switch cabinet.
