Description
The model FLRU level transmitter with reed-chain technology in combination with the WIKA model NETRIS ® 3 radio unit is used wherever web-based remote monitoring of level measurement in liquid media is desired. Condition-based and preventive maintenance through centralised big data analysis is thus possible.
Level transmitters of this model series work on the float principle with magnetic transmission and are used wherever centralised, web-based remote monitoring is required. The float's magnetic system in the guide tube actuates a resistance measuring chain that corresponds to a 3-wire
