Metrological support for measuring the flow rate and volume of cold water, wastewater in SUE «Vodokanal of St. Petersburg»
Summary
Regulatory and technical measures required for the metrological support of measuring the flow rate and volume of water and wastewater are considered. The measures form the core of reliable measurements at the facilities of SUE «Vodokanal of St. Petersburg» and include: standardization of the measurement accuracy; developing or updating regulatory documents; developing a reference base for calibration and verification of flow meters, water meters; establishing an accounting system for water and wastewater volumes; metrological examination of projects of water and wastewater metering units and authorization for operation of water and wastewater metering units; designing and improving water and wastewater metering units; developing the instrumentation pool; providing for the metrological control and supervision over the condition and operation of measuring instruments in the water supply and wastewater disposal systems; training qualified engineers-metrologists.
