Why choose it

ECOR6+ NB-IoT is a TYPE 1 volume converter, compliant with European Directives 2014/32/EU (MID) and 2014/34/EU (ATEX), specifically designed to meet the requirements of the UNI TS 11291 standard and of Resolution 155/08 of the Italian Regulatory Authority for Electricity and Gas for metering units ≥ G10.

ECOR6+ NB-IoT converts (PTZ, PT or T conversion) the volume measured by the meter to standard reference conditions (base conditions).

As standard, the device has two digital outputs: one for the repetition of the converted volumes and the other for alarm signalling.

Data protection and the integrity of the programming parameters are ensured both by sealable switches and by programmable passwords.

ECOR6+ NB-IoT is battery powered.

Data communication

  • NB-IoT communication (narrowband)
  • DLMS protocol
  • Local communication via ZVEI infrared optical port according to EN 62056-21

Functionality

The measured volume is converted using an algorithm that requires the following variables:

  • The gas volume measured by the meter: acquired by the device through the pulse input.
  • The temperature: measured by the external digital temperature sensor.
  • The gas pressure: measured by the external digital pressure transducer.

Gas properties

The device calculates the gas compressibility factor using standard methods or a constant value, and then provides the converted volume (in standard m3).
