Pulse counter Vega GM-2
Return to catalog
Pulse counter GM-2 is designed to take readings from Elster gas meters, with the subsequent accumulation and transfer of this information to the LoRaWAN® network.
Pulse counter is equipped with Hall sensors, one of which calculates the current meter readings and the other is located in such a way and has a sensitivity level that reacts only to the presence of an external magnetic field (for example, when a strong magnet is placed near the gas meter to disable the counting mechanism).
To protect against unauthorized access, pulse counter has a tamper. There are also two security inputs and two open-drain outputs for control of an external devices.
Pulse counter is powered by a 3600 mAh SAFT battery. Pulse counter acts as a LoRaWAN® device of class A.
