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.
Passing through the counter, below this mark it is considered cold at the rate, and the rest as hot. Payment costs with such a hot water meter will be significantly reduced. Although its high cost deters many buyers, despite the fact that over time the costs will pay off. This is especially true for apartment buildings, where water flows cold through pipelines for a long time.

- 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.
Radical DIY solution
If all the actions listed above did not change the situation, as before, the hot water meter fogged up, what should I do? In this case, you should invite the wizard to fix the problem, or try to isolate the pipe from the device yourself. To do this, use:

They are produced in two types: turbine and impeller. The former are used for pipes whose diameter is in the range from 50 to 200 mm, the latter - up to 40 mm. The device from a well-known manufacturer will be supplied with documentation, has a guarantee and service. In addition, the meter must be with a factory seal and an OTK stamp in the documentation.
