The service is active since 2006, year of production of the first Italian meter with integrated solenoid valve: Zenner Gas Blocker.
It works only with Smart Meters prepared for the management of prepaid options like those produced by Zenner Gas.
Prepaid GAS, initially created only for users that tend to be defaulting, has also found application with an eye on optimisation of consumption, and rationalisation of expenses related to energy requirements.
Operation is extremely easy and similar to that of prepaid mobile phone contracts.
The customer uses the m3 of gas purchased and receives an alert message when a previously set value of remaining m3 is reached.
In the case a customer does not want to purchase more m3 (recharge) and consumes the entire credit, the meter will be automatically closed.
Once a new recharge is made (payment and permit sent by TekGas control system), if the credit was not used up (the solenoid valve of the meter is opened), it will be summed to the remaining m3.
If the credit has been used up (the solenoid valve of the meter is closed), the customer will follow a simple process to immediately reactivate the gas supply.
