• Natural gas Smart Meter with remote communication module

The Wize G4 meter is a volumetric measuring instrument for H, L, E families of gas, using diaphragm system for residential use. It is designed and built according to the highest standards, in compliance with the EN1359 norm and the MID directive. Measurement precision and accuracy is guaranteed by the production and control process, and by an automated calibration system, which is used at the internal Metrological Laboratory upon 100% of the meters manufactured.

The quality of the plastic and metal components makes the meters highly sensitive, even with a minimal gas flow, and ensures excellent
performance over time.

The Wize G4 has an integrated electronic module with the following features and functions :

  • logging of consumption values
  • remote transmission of the readings
  • remote firmware download
  • remote parameter setup

The pressure difference between the meter's intake and outlet results in the cyclic filling and emptying of the measuring chamber via the alternating movement of the deformable membrane.

The motion is converted into gear rotation via the kinematic measuring system, which consists of spool valves with a connecting rod/crank coupling. The rotation of the gear is then transmitted to the electronic module through a target wheel and an inductive sensor.

The meter is equipped with an effective fraud detection system.
