Cold water metres

For cold water

— metres designed for use with cold water. If such a model is intended only for cold water, then the maximum allowable temperature for it most often does not exceed 40 °C. However, there are also more "heat-resistant" devices — up to 50 °C; such a metre can be useful if the “cold” pipe is periodically heated (for example, from sunlight), and quite warm water can flow through it.

This category also includes combined devices designed for both cold and hot water; for more details see "Water temperature".
