Product description

Overview:
The meter measures heat released by flow that travels through heat exchange systems and is mainly used in collective heating residential areas with hot water as the medium. The meter measures the heat value consumed by users. The meter measuring precisely, which is built with overall structure, is nice looking, easy to install, and has complete functions. It is widely used in heating facilities that adopts collective heating and household based measurement of heat.

Features:

  • The flow meter adopts non-magnetic technologies and will not absorb iron rusts and debris in the water. It’s designed for long-time use and accuracy measurement.
  • Spiral backwash and other practices are used to ensure the even flow rate of the vane wheel to effectively overcome unilateral wears of a single direction; no straight pipeline is needed to adjust the water flow.
  • The dedicated chip of the temperature sensor ensures a temperature measurement error of 0.01℃.
  • Imported low consumption single chip with minimum static current. The single chip will guarantee a service life of six years if used with dedicated batteries.
  • LED displays accumulated heat, water inlet temperature, backwater temperature, total flow and instant flow and other information.
  • The display part is 360 degree rotatable and 90 degree foldable; easy reading, one-key design and easy operation.

Remote reading function: total line structure, easy construction; remote reading system integrating collector, concentrator and wireless network in M-bus construction makes it easy for statistics and inspection.
