S&DL Water Level Meter

S&DL (Sensor and Data Logger) Water Level Meter has a pressure sensor and a data logger as a unified unit. This instrument consists of the unified probe in the water, the battery case on the top of a monitoring well and the cable with bent tube to connect between the probe and battery case.

This is high accurate and long durable digital water level meter which can directly read water level and also automatically correct atmospheric pressure.

Retrieving data and monitoring setting are easily carried out using a laptop computer with S&DL Assist (software) at the site.

User can expand this stand-alone monitoring system to remote monitoring system using GSM i-SENSOR data transfer unit smoothly/reasonably.

User can use this for long-term groundwater monitoring, surface water monitoring, field permeability test / pumping test and so on.

Feature

  • It makes possible to have superior stability by putting data logger in the water where temperature rarely change. Because of applying the unified probe consisted by the sensor and data logger, it is not affected by exogenous noise.
  • A special construction work and/or equipment are not needed, and user just set the battery case at the top of a monitoring well/hole.
  • Water level can be directly read.
  • Corrosion resistance titanium body of the probe can be provided (Model-4640).
  • It is low power consumption instrument, it is available long term monitoring with size D alkaline three (3) batteries.
