Descripion

      With the increasing requirement for environmental protection of heating system, the heating mode has changed accordingly. The ultrasonic series heat meters are newly developed according to the standards of CJ128-2007 and EN1434 of the Ministry of National Construction of China, and have the super-long service life of battery-powered large and small caliber ultrasonic series heat meters.

     The water meter adopts the latest domestic advanced ultrasonic time difference measurement technology developed by the company, which has the remarkable characteristics of high accuracy, ultra-low power consumption, wide range ratio, stability and reliability. Integration scheme is adopted in the structure. IP68 protection level can be achieved through good sealing, even if the instrument chamber water intake can ensure long-term reliable work.

Application

      This series of heat meter solves the problems of traditional mechanical heat meter such as easy blocking, idling, low flow rate without metering, excessive pressure loss and so on. It can be widely used in urban heating pipes, heating tables of residential buildings, heating systems (i.e. the main pipes of heating boilers or heat exchange stations or zonal main pipes), as well as refrigeration systems.

Features

● Dual-channel ultrasonic probe is used to measure the pipeline. The measurement is accurate and reliable, and there are no moving parts；

● Wide range ratio and low starting flow；

● With electronic lead sealing function；

● Positive and negative measurements can be made；

● Display abundant information, the same interface shows 8-digit cumulative traffic；

● With intelligent power-saving design, the instrument will turn on the power-saving mode in the long-term fluid static state or Empty Pipe

● With intelligent power-saving design, the instrument will turn on the power-saving mode in the long-term fluid static state or Empty Pipe；
