May a water supplier re-seal a SGV-15 meter through the holes in the nuts of the fittings while preserving the manufacturer’s sealing ring safe?
According to Clause 81 (11) of the Terms of providing public services to owners and users of premises in apartment buildings and houses (approved by RF Government Decree No. 354 dated 06.05.2011, as amended on 25.12, 2015), a meter must be protected from unauthorized interference.
According to Clause 3 of GOST R 50193.2 “Measurement of water flow in closed channels - Water meters for cold drinking water - Requirements for installation”, “When installing a meter, the following accessories are used: 3.1.4. If necessary, seal the connection of a meter with the supply pipe in order to detect the unauthorized removal of the meter.”
In accordance with these requirements, water suppliers carry out additional sealing of the place of connection of the device with a water supply.
What is the procedure for replacement of old meters with new ones at additional charge for individuals and self-employed persons?
A replacement service at additional charge is a counter purchase-sale, i.e. MCC BETAR Ltd. buys old meters, and in exchange sells new meters in the same quantity at a reduced price.
Both SGV, SKHV-15, 20 water meters manufactured by MCC BETAR Ltd. with expired warranty period or expired calibration period, and third-party water meters with Du15, 20 with brass casing shall be replaced at additional charge. SG-1, SGBM-1.6 gas meters manufactured by MCC BETAR Ltd. shall also be replaced at additional charge. The prices for purchase and sale are specified in the price list for additional services on www.betar.ru.
To replace the meters, the consumer shall submit the following data: a replacement application specifying the quantity and type of meters, his/her passport data and TIN. Based on the data received, a contract of exchange will be concluded and an invoice will be issued to the consumer. Old meters can be delivered to MCC BETAR Ltd. in several ways: by mail, transport company to Kazan and directly to the manufacturer.
After paying the bill and signing the contract, new meters will be sent to the consumer in the same way.
Who shall calibrate the meters? Where shall the meters be calibrated, directly on the site of their installation or shall they be sent anywhere?
According to paragraph 3.16 of the Metrology Regulations 50.2.006-94 “Procedure for calibration of measuring instruments”, the owners of measuring instruments shall provide the delivery of measuring instruments for calibration.
You may contact the nearest center of standardization and metrology for calibration, usually periodic calibration services are rendered by them.
There is a possibility of calibration without dismantling the meter using portable calibration installations. As a rule, periodic calibration is carried out by regional standardization centers (Centre of Standardization, Metrology and Certification) and their branches.
Why is a calibration interval calculated in years, not in cubic meters?
There are situations when a meter is installed, but water is not almost consumed, a water supplier requires calibration or replacement of the meter, and the meter shows only 10 cubic meters.
Is it possible to revise a calibration period taking into account the volume of the “counted” water. A water meter is a means of measurement and is subject to mandatory calibration when released from production and periodic calibration at certain calibration periods that are not related to the volumes of accounting water in accordance with Metrology Rules 50.2.006-94.
A calibration period is established by the Federal Agency for Technical Regulation and Metrology of the Russian Federation (Gosstandart of Russia (State Committee of the Russian Federation for Standardization and Metrology) when approving the type of device.
The manufacturer does not have any right to change the established frequency of calibration.
The time for calibration of the water meter expires. What should I do to extend the operation of the meter?
After the expiry of the calibration period, it is necessary to carry out periodic calibration of the device (section "Maintenance" of the operation manual (certificate) for the device).
Upon positive results of periodic calibration, the device is allowed to be operated during the next calibration period, however, if the device has not been tested within the specified time, it can not be used for water measurement.
As a rule, periodic calibration is carried out by regional standardization centers (Centre of Standardization, Metrology and Certification) and their branches.
SGV-15 water meter is kept in storage, can the meter be installed without calibration after storage?
A water meter is a measuring device and according to Metrology Rules 50.2.006-94 “The procedure for calibration of measuring instruments” is subject to mandatory calibration when released from production and periodic calibration after certain calibration periods that do not depend on whether the meter is installed or is in in keeping.
According to Clause 2.14 of Metrology Rules 50.2.006-94 “Exceptional calibration of measuring instruments ... conducted while commissioning of measuring devices after long-term storage (more than one calibration period).”
Thus, if a meter is stored for more than one calibration period (specified in Clause 188.8.131.52 of the operation manual (certificate), it can not be used for measurement without calibration, but if the device is found to be appropriate according to the results of calibration, the device can be installed.
From when is a calibration period calculated?
May I use the meters that have expired calibration period?
A water meter is a measuring device and according to Metrology Rules 50.2.006-94 is subject to mandatory calibration when released from production and periodic calibration after certain calibration periods.
At the end of the calibration period, the device is subject to mandatory periodic calibration. Upon positive results of periodic calibration, the device is allowed to be operated during the next calibration period, however, if the device has not been tested within the specified time, it can not be used for water measurement.
What about water measurement during calibration?
According to Clauses 59, 60 of the Terms of Providing Public Services to Owners and Users of Premises in Apartment Buildings and Houses (approved by RF Government Decree No. 354 dated 06.05.2011, as amended on 25.12, 2015, amdt. No.16):
In the event of failure, loss or during a calibration period of the meter, from the date when the specified events occurred, and if the date can not be established, it starts from the estimated period in which the specified events occurred, until the date when the utility consumption measurement was renewed by putting into operation of the metering device that meets the established requirements, but not more than 3 measurement periods in sequence for dwelling premises and not more than 2 measurement periods in sequence for a non-residential premises; volumes (amounts) of consumption of cold water, hot water, domestic wastewater for calculation of the amount of utility bills are calculated on the basis of the calculated average monthly volume of consumption of a communal resource determined by the indications of an individual or common (apartment) meter for at least six months, and if the period of operation of the meter is less than 6 months - then for the actual period of operation of the meter, but not less than 3 months.
After the specified maximum number of calculation periods, the fee is calculated based on the norms of consumption of the relevant public services.
