Radar type level meter

MWLM-PR26 series
MWLM-PR26 series
2 line system microwave level meter and lightweight.
HART communication enables remote adjustment.
 

Installation and wiring are easy due to the adoption of the 2-wire system and HART communication. Can measured objects from liquids to powders. Intrinsically safe explosion structure is also available.

  • For liquid
  • For liquid

Various antennas are available, including cone and horn types.

 

Features, keys

  1. Stable measurement
    Measures levels without contact in harsh environments such as in high temperatures, high pressures, steam, gas, etc.
  2. 2-line system
    The meter employs a 2-line system, so you do not need to put up new power lines. Just connect to conventional DC lines.
  3. HART is provided as standard
    The meter outputs a HART signal as well as a 4 to 20 mA DC current signal. This makes it possible to connect the meter directly to a computer.
  4. Explosion proof design
    Intrinsically safe explosion structure is also available. (Exia II BT4)
 

Usages, use examples

  • Detect and measure liquid levels continuously without contact
  • Measure corrosive and adhesive materials
    Ex.: Monitor city water level, sewage, drain liquid, chemical agents (acids, alkalis), slurry, storage tanks, silos, etc.
