Radar type level meter
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.
Various antennas are available, including cone and horn types.

Features, keys
- Stable measurement
Measures levels without contact in harsh environments such as in high temperatures, high pressures, steam, gas, etc.
- 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.
- 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. - 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.
