Tubular ultrasonic heat meter KLD-3000R-Dalian Kelide Technology Co., Ltd

Tubular ultrasonic heat meter KLD-3000R

This series of products complies with the national standard of the People’s Republic of China, GB/T 32224-2015, 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; it thereby measures and displays 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 it to serve multiple purposes and meet 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 remote reading is possible in any area where there is GSM network coverage.

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#>
