Horizontal Woltmann meter with removable mechanism. Sealed register with magnetic drive for direct reading on number rollers.

The IWM-LR4 has been designed to allow wireless remote reading in various types of commercial and industrial applications.

The radio module, thanks to the inductive target on the meter dial, allows reading the counted volume without access constraints to the site, using Long Range LoRa radio technology in compliance with the LoRaWAN standard, making the device integrable into multi-service networks.
