该系列产品执行中华人民共和国国家标准GB/T32224-2015《热量表》标准,管段式超声波热量表是利用超声流量传感器和温度传感器测量供水流量及供、回水温度差,进而测量及显示水流经热交换系统所释放或吸收的热量仪表。可实现“冷”、“热”双向独立计量功能,一表多用,满足不同用户的需求,应用于供热管网的在线计量,组网方式适用于大型的供水系统管理以及水资源用水量监测,只要有GSM网络信号覆盖的任何地方,都可以采用无线网络自动抄表。温度传感器分为插入式和外贴式,两线制PT1000铂电阻。
This series of products complies with the national standard of the People’s Republic of China, GB/T32224-2015, titled \"Heat Meters\". The tubular ultrasonic heat meter utilizes ultrasonic flow sensors and temperature sensors to measure the flow rate of water supply as well as the temperature difference between the supply water and return water, thereby determining and displaying the amount of heat released or absorbed by the water as it passes through the heat exchange system. It offers independent measurement capabilities for both cold and hot water streams, allowing multiple functions from a single device and meeting the needs of different users. It is used for online measurement in heating networks, and its networking capability is suitable for managing large-scale water supply systems as well as monitoring water consumption. Wireless data collection is possible in any area with GSM network coverage. The temperature sensors are available in inserted and surface-mounted types, and they are based on two-wire PT1000 platinum resistors.<#>4#>
