IWM-PL3

Electronic pulse emitter module for multi jet meters with inductive interface

The IWM-PL3 is suitable for remote reading applications in commercial and industrial sectors, acting as an electronic pulse-emitter. It allows the acquisition of the consumption of the counter by third-party systems with a universal interface and integrating advanced counting functions and fraud detection.

The use of an inductive target on the meter dial excludes the possibility of magnetic fraud and makes the application insensitive to the pipes vibrations.

The IWM-PL3 is compatible with all the pre-equipped multiple jet meters (wet, semi-dry & dry dial).

Consumption analysis (with incremental and decremental counting), Reverse flow compensation can be activated for having always perfect alignment between the totalizer and the meter.

Checking frauds (cable cut and tampering, detection of external magnetic field application, reverse flow). The presence of reverse flow can be monitored with a dedicated impulse contact.

Dedicated dosing function available for industrial applications.

IP68 protection* allows the use of the module also for meters installed in difficult environments.

NFC interface allows configuration and commissioning of the device with the use of a simple smartphone app (available ratio values K = 1, 5, 10, 25, 50, 100, 250, 500, 1000), and being able to configure the duration of the output pulse according to the sensitivity of the acquisition system.

White

Simple counting wire, NO contact Closes every index revolution, independently from the flow direction

Yellow

Fraud wire, NC contact, Opens at the following alarm conditions: Module removal, Inductive target tampering, Cable cut, Magnetic tampering

Green

Third wire, NO contact, it can be assigned to one of the following features: Absolute counting (closes every index revolution during forward flow, with backward flow revolution compensation), Backward counting (closes every revolution during back flowing), Dosing (closes every XX liter, with XX freely settable)
