Полное описание

Meters of cold and hot water made in accordance with GOST R50601 are designed for individual water consumers when measuring the volume of drinking cold and hot water, including – with the transfer of data through communication lines.

The meters correspond to the performance of a B4 class in accordance with GOST 12997 in relation to resistance to effects of temperature and humidity of the ambient air. According to metrological classes, the meters correspond to class B for horizontal installation or class A for vertical installation in accordance with GOST R 50193.1. For remote transmission of measurement results it is recommended to use water meters with pulse output (sealed switch) with a resolution of 1 litre. Water meters have a highly effective protection against the influence of magnetic fields of permanent magnets.

Limits of the permissible relative error in measuring the volume of flow:

  • ± 5% in the range from Qmin to Qt;
  • ± 2% in the range from Qt to Qmax inclusive.

Calibration interval:

  • when used on hot water - 4 years;
  • when used on cold water - 6 years.
