Household meter calibration laboratory
The metering device calibration laboratory provides a service for the verification of metering devices for electric energy, natural gas, drinking and hot water for legal entities and individuals.
In order to fulfill the decree of the Cabinet of Ministers of the Republic of Uzbekistan dated 20.08.2019 №698 “On approval of administrative regulations for the provision of public services for the removal, verification and installation of metering devices for electricity, natural gas, drinking and hot water of legal entities and individuals” verification of metering devices.
Note: In accordance with the decree, applications for the removal, verification and installation of metering devices (electric energy, natural gas, drinking and hot water) are made in the center of public services or in a single interactive portal of public services. Removal, installation, repair or replacement of metering devices is the responsibility of the supplier organization.
For the convenience of working with requests from users and consumers, the “national institute of metrology of Uzbekistan” created the personal software metrologiya.nim.uz. At this time, the software system has been turned into a single interactive portal of public services, this system receives applications.
With the help of this program, consumers who wrote an application can enter their personal ID number or serial number of the metering device and be notified of the status of the metering device verification or download the conclusion. In addition, certificates and notifications of metering devices are protected using a special QR code and are stored electronically in the database. And this in turn:
- Convenient for the population;
- Prevents forging certificates and notifications;
- Allows you to download a certificate or notification at any time via the Internet.
To use a personal QR code, simply scan a square QR code using your phone.
The metering device calibration laboratory is equipped with devices from the Republic of Korea and China for automatic verification of metering devices for electrical energy, natural gas, drinking and hot water.
Today the laboratory for checking metering devices has the following capabilities:
- Calibration of one and three-phase electrical energy meters with an accuracy of 0.05 class, current strength 3×0.1÷120 A, voltage 3 57.7 380 V;
- Calibration of natural gas metering devices from G4 to G10 with an accuracy of class 0.02 from 0.04 m3/h to 23 m3/h;
Calibration of metering devices for drinking and hot water with a diameter of 15 to 32 with an accuracy of 0.5 from 0.03 m3 /h to 30 m3/hh.
