Types of hot water meters

Specialized stores offer various hot water meters. One of the most common options is considered single-tariff. It produces a report of cubic meters immediately after turning on the tap. But the water cools down a lot during the night, and in the morning, instead of hot, cold water flows for a long time, which is paid at the hot rate. To solve this problem, multi-tariff metering devices with a temperature sensor are produced. According to the norms, water is considered hot if itthe temperature is over 40 degrees.

  • At a sudden change in temperature. In summer, when hot water is turned off for a long period, and then turned on, small droplets of water may appear on the meter glass, which disappear over time.
  • Loss of elasticity of the seal due to prolonged use of the device.

As a result of the occurrence of one of the listed reasons, it is necessary to take certain measures to eliminate it.

  • Knock on the glass of the appliance or the pipe to which it is attached. Droplets of water will fall down and it will be possible to consider the readings of the device. Be careful not to damage the meter.
  • Drill a small hole in the glass, moisture will evaporate through it, and the visibility of the numbers will be good.
