Hydrophones for Monitoring Leakage in Water Supply Networks

RHSA-30Hydrophones for Monitoring Leakage in Water Supply NetworksThe sensitivity is -172dB. The pipeline leakage noise monitoring hydrophone, combined with high-frequency pressure sensors and data acquisition and transmission equipment RTU, can simultaneously monitor the occurrence of water hammer leakage in the pipeline, prevent pipe bursting, and improve daily management level. The hydrophone is directly connected to the water body through exhaust valves, flow meters, water meters, or fire hydrants on the pipeline to listen to the leakage noise transmitted in the water. A pipeline leakage monitoring system can monitor small leakage signals in the pipeline network, equipped with suitable collection equipment, wireless transmission equipment, monitoring software, etc. A set of pipeline network leakage monitoring system is formed. Our company has relevant practical application cases for inquiry.

Advantages and Features:

1、RHSA-30Hydrophones for Monitoring Leakage in Water Supply NetworksMonitor the abnormal sound of pipeline leakage, form a hydrophone sensor array through wireless networking, and use the time difference detection technology of leaked signal propagation to obtain the location and leakage situation of pipeline leakage.

2. The wireless hydrophone sensing array system is a scientific monitoring and early warning system. The system has high sensitivity, strong applicability, and good real-time performance, and can achieve single point high-precision vibration signal detection and positioning, as well as multi-point vibration synchronous detection and positioning.

3. Good directionality. The hydrophone has no directionality horizontally and no directionality within a range of 240 ° in the vertical plane.

4. High sensitivity and flat response.

5. Good stability and high reliability. Hydrophones have good temperature, pressure, and time stability, high reliability, and are suitable for underwater acoustic calibration.
