In small heating systems, when artificial water is released or a large heating water leak occurs, if the secondary network is supplemented with cold water, the overall temperature of the terminal will not meet the heating load requirements, and the recovery time is also long. By identifying the instantaneous replenishment flow, it automatically selects the primary network return water replenishment or cold water replenishment, which can ensure the stability of the secondary network operation and the heating comfort can meet the requirements. The structure of the traditional side leakage device is relatively complex, which makes the leak detection device have certain failures, affecting the efficiency of leak detection; and the detection device cannot be applied to the installation requirements of pipes of different sizes, affecting the practicality of the detection device.
