Metrology Centre

VodoTech was issued by the Czech Metrology Institute (“ČMI”) the Certificate on Metrology / Technical / Personnel Competence, pursuant to which VodoTech may check certain metering equipment. VodoTech is also certified pursuant to ISO 9001 for this activity.

Regulation and verification of water meters

The repaired water meters are verified by OVOD in AMS using own equipment: DN 15-30 for hot water meters and DN 15-100 for cold water meters. Big water meters are, after being repaired, verified in cooperation with verification third party centres which are authorised for the Czech Republic.

Each water meter which fulfils essentials set forth for the water meters (and can be used for billing) has an official marking, K63, on it. Such water meter with the official marking can measure consumption of cold water for 6 years and consumption of hot water for 4 years.

The official marking is a legitimate proof of function of a meter and it is not necessary to issue other verification evidence. Upon customer’s request, the water meter can be issued a verification certificate.

Re-testing of the water meters during validity of their certificates, calibration, and random-testing

During validity of certificates, the water meters are re-tested in case of doubts whether they work properly. Once the test is completed, the client will receive the test certificate which will include information about flow rates.

If a water meter fails the tests, it cannot be used for metering. Each test protocol needs to be confirmed with an official stamp with the state symbol. Calibration is carried out in order to check exactly the measured values. A calibration protocol contains the measured data. It does not include information whether the metering device is, or is not, compliant. Such water meter does not have an official marking on it.

Random testing of water meters is carried out in order to find out the condition of the water meter. A protocol of check testing provides information about the measured data.

VodoTech installs and replaces water meters in apartments. This activity is carried out on the basis of the Certificate No. 7001-OR-0012-08 which applies to repairs and installation of water meters. Prices are quoted individually and depend on our capacities.
