Technical Description


Utilizes advanced sensor technology to monitor water hammer effects in water supply networks in real-time, effectively preventing pipeline ruptures and equipment damage. Combines high-frequency pressure sensors, hydrophones, and intelligent analysis platforms to achieve high-precision localization and rapid alerts, ensuring safe and stable operation of water supply systems. Applicable to water supply networks, hydropower stations, steam systems, etc., enhancing pipeline system safety and service life.

The WTC-WS120 intelligent pressure monitor is designed for multi-scenario pressure monitoring in gas pipelines, thermal pipelines, water supply pipelines, etc., employing high-precision, high-range pressure sensors to detect sudden pressure changes and leaks. The device features an e-ink display showing time, signal status, battery level, pressure values, temperature, and humidity.

Equipped with an N-type antenna port and a default integrated waterproof antenna, it supports replacement with fiberglass antennas in poor signal environments. Utilizing 4G CAT1 for cellular communication, it ensures reliable data transmission without signal coverage issues and eliminates the need for gateways required by private wireless protocols. With ultra-low power consumption, its built-in lithium-thionyl chloride battery supports continuous operation for over five years. Integrated Bluetooth Low Energy (BLE) enables convenient on-site debugging and device connectivity.
