BM 102 3
Device description and range of applications
The BM 102 MICROFLEX level gauge uses the Time Domain Reflectometry (TDR) measuring
principle and two-wire technology for level measurement. It is designed solely for measuring the
distance, level, volume and ullage of liquids, pastes, slurries and powders. It can continue to
measure the level or distance of the top product and total volume in applications with two or more
products.
The level measurement data can be displayed and the gauge configured using either a HART
Handheld Communicator console (HHC) or a PC work station equipped with PCSTAR 2 software
which is supplied as standard with the gauge.
