Can I change a new electronic counter to another?
We have an old apartment building (70 years old) with wiring that never changed. There was an ancient meter, two years ago, at the request of a change, we decided to take an electronic two-tariff Energomera and made money as a result of problems. Not only that, it now counts exactly twice as much, but it also counts 4 kW per day and 2 kW per night. Moreover, regardless of what is connected. If we lived in the country for two months - the situation is unchanged, although only a small refrigerator worked, it also burned out 120-125 for a month of daytime and 60-65 of nightly. Total 180-190 kW. Arrived - similarly. We live together, lamps, LEDs, washing about once every two weeks at night, one TV at night for an hour and a half. Very rarely iron and vacuum cleaner. No stoves, no crock-pots, no hairdryer. Gas. Previously, no more than 100-115 kW came out.
An electrician was called out of the house management - he said that it was probably an ancient wiring, change the counter to Mercury 201, in our house everyone has one. I called the Electricity Network, but they are not eager to accept an application, such as a new meter, let's just reconfigure it to a single tariff (although that’s not the point). Can they refuse a replacement? I want to buy a counter from them, and the masters also order from there. And will I have to overpay now? Husband swears, says smash, but this is also not an option, I guess. Please advise what to do.

Hello! This is a common problem. One of the verification methods is to see how many pulses per kW are indicated on the front panel. It happens that he really considers them twice as fast. The fault of energy sales employees, or someone else, or marriage - is unknown. In any case, the energy sales company usually claims that the old meter “sinned” in a smaller direction, and the new one shows “true”.
This problem has been repeatedly discussed at thematic forums. You can connect a known load and see how much the kW / h meter will show after a certain time. But there may be a problem in the wiring - you can ask an electrician to measure leakage currents or insulation resistance.
At your expense, they should not refuse to be replaced. Insist that the matter is not in the tariff, but in the measurement errors (if you make sure that the wiring and measuring the real readings are known at a known power consumption - in other words, verification).
Mercury 201 is a fairly common model.
