  • Who performs the installation of heat meters?

Installation of our heat meters with a radio modem is the same as of ordinary meters. Installation can be done by any regular plumber! Set and forget!

Installation of intermediate equipment: concentrators, repeaters or retranslators is not required. So, you will save your money for equipment and installation!

  • What happens if meter fails?

If our heat meter fails, our technical support will perform remote diagnostics. If the falure is confirmed, we will replace this device according to the warranty obligations.

Warranty for heat meter and radio modem is 24 months, and average service life – 12 years.

  • What happens if the gateway does not receive a signal?

If the communication session with gateway failed, all the data accumulated by the meter will not be lost and will be sent during the subsequent session. After that, statistics for the missing period will be displayed in your CloudMeter.

  • How to connect heat meter to network?

There are two ways:

  1. Deploy telemetric network of Fenix Link within your city, for instance. It’s no-charge connection.
  2. Or you can deploy your private network using our radio Fenix gateway— operating range: up to 10 km within city, up to 40 km in open areas.

In both cases, all data from heat meter will be transmitted via the Internet to yout CloudMeter.

  • What is the radiant power?

The radiant power is up to 25 MWth. It is 80 times weaker than a cell phone signal. Data are transmitted in a matter of seconds. It’s completely safe.


High reliability.
Installation is cheaper. Price is lower.


The less equipment — the lesser budget.​


Price for our heat meters is well below its analogues.


Mitigates losses up to 3-4%! Real-time captures every loss and unbalance.
