The IWM-PL4 is a non-magnetic pulse emitting module suitable for numerous applications for remote reading in residential, commercial and industrial installations applicable to the series of woltmann water meters mod. WDE-K50.
It allows the acquisition of meter consumption by third-party systems with an universal interface and integrating advanced counting and fraud detection functions.
The use of an inductive target on the meter excludes the possibility of magnetic fraud and makes the application insensitive to the vibrations of the pipes.
