Non-magnetic Smart Heat Meter

Descripion

      With the increasing requirement for environmental protection of heating system, the heating mode also changes. The non-magnetic mechanical calorimeter is newly developed according to the standards of CJ128-2007 and EN1434 of the Ministry of National Construction of China. It also has intelligent long-distance transmission and long service life of Residential non-magnetic Smart Heat Meter.

       The water meter adopts the latest domestic leading non-magnetic measurement technology developed by the company, which has the remarkable characteristics of high accuracy, ultra-low power consumption, wide range ratio, stability and reliability. Separate mechanical seals are adopted in the structure, which can play a good waterproof effect and facilitate installation and maintenance.

Application

      The series of heat meters solve the problems of short service life of traditional mechanical water meters and difficulty of manual meter reading. It can be widely used in heating sub-meter and heating system of residential area users (i.e. the branch of heating boiler or heat exchange station), as well as in refrigeration system (air conditioning).

Features
