5.2 

Metrology Compartment Tamper Detection 

It is impossible to remove the black plastic metrology protection cover without removal 
and therefore damage to the metrological seal. This seal also holds in a tab from the 
identification label. Any attempt to remove either the identification label or the metrology 
seal will cause indisputable physical evidence. It is impossible to remove the index 
assembly without first removing the black plastic metrology cover. 

 

5.3 

Magnetic Tamper Detection 

 
The use of a strong magnet (strength >200mT) will be detected and an alarm will be 
flagged. An alarm symbol and error message can be displayed on the LCD. In addition, 
this alarm will be visible to the HES via the HAN. Lower strength magnets will not cause 
a problem to the device. 

 

5.4 

Encryption 

The meter uses AES (Advanced Encryption Standard) method 9. 

 

6. 

Memory 

Configuration and Security data is kept in an internal flash in the microprocessor and is 
loaded at manufacture and never changed again. 
 
All other data is held in external memory (Flash or EEPROM) 

7. 

Supply Valve (Electro Valve) 

The electrically operated ball valve is located close to the output connection of the gas 
meter. It is connected electrically to the electronic index via a fully insulated ceramic 
connector and fire proof cable.   

 

Lifetime 20 years of operation in gas, >4000 cycles      

  

ATEX Zone 1 certified (complete gas meter) 
Operating voltage: 2.8 

– 3.6 V DC 

Protected by: Zener diodes 
Position indication on LCD 
Reliable limit switch 
Leakage: < 1 L/h @ 75 mbar (acc. to EN 16314:2013) 
Pressure Drop : <2 mbar (air) at 6 m
