What is the principle of water leak detector?
Different occasions have different identities. Just like water leak detectors, it's the same. The following is an introduction to the server room and the server room outside the water leak detector.
Outside the Server Room - Tap Water Leak Detector
Working Principle: Water supply pipeline leakage, the water and leakage pipe friction, as well as with the surrounding media, such as impact, will occur at different frequencies of vibration, heating pipeline leakage meter, which produces water leakage sound. In the pipeline damage, water leakage will constitute sound waves and sinusoidal curve method to the pipeline on both sides of the flow, and caused by the pipeline vibration, at the same time, in the break at the rapid jet of water, the impact of the pipeline around the media, resulting in the existence of a special frequency of the leakage of sound, by the surrounding media and pipeline spread to the ground. Identify leaks in the water supply pipe network, individual leakage sound method of detecting leaks, which is the fundamental principle of leak detection.
Server Room - Water Leak Detector
Working Principle: The server room water leakage detector is composed of an inductive cable for detecting liquid leakage and a controller with a location alarm. When leakage occurs, the inductive cable sends the signal to the controller, which is processed by the microprocessor, and then uploads the leakage location through the communication protocol to the monitoring host computer and the alarm is raised at the same time.
The inductor cable consists of 4 (or 2) wires of different types, two of which are processed from conductive polymers, whose resistance per unit length is precisely processed and constant. When there is no leakage, the current value between the two wires is normal, when the inductive line is stained by the leakage, the two conductive polymers are shorted between them and the measured current value changes, the controller, according to Ohm's law, the resistance is related to the length, and through the measurement, the location of the leakage point where the fault occurs can be obtained.
Water Leakage Detection Role
1. Prevent water waste and save effective water resources. Many urban areas because of the aging of the water supply pipeline, there is a serious run, risk, leakage, wasting a lot of water resources. Pipeline leakage detection can reduce the leakage rate of water supply pipe network.
2. Saving project investment and water supply cost. Due to the continuous development of urbanization, water consumption continues to increase, urban water supply enterprises have to increase investment to introduce more water sources to meet the demand for water supply. If the water supply pipeline leakage is reduced, it will reduce the amount of water taken from the water source and the workload of the water plant, reduce the water plant capital investment and water supply costs.
3. Excluding potential leakage safety hazards. Water pipe leakage time on after, will produce scouring of the soil foundation, resulting in soil erosion, resulting in the loss of support around the pipeline, and finally will cause the road surface collapse, and even produce ground subsidence.
