Integrated Groundwater Telemetry Unit(Model YDH-1L)
- Description
-
Overview
The Integrated Groundwater Telemetry Unit is an intelligent data acquisition terminal that uses a high-precision,high-stability pressure sensor as its pressure sensing element.Equipped with a built-in 4G transmission module(and BeiDou communication module),it is widely used for groundwater and emergency water-level monitoring.The device enables scheduled data collection,storage,and transmission.
Application Conditions and Scope
The device is suitable for monitoring water bodies and water levelsin groundwater observation and emergencyresponse scenarios.
