WATER MONITORING SYSTEMS
Automatic Water Level Monitoring System
The automatic water level monitoring system is used to get administers significant quantitative data on the magnitude of the water column, water table and the temperature in a borehole. The system contains an absolute water level sensor with a cable and an automatic data logger with the required data retrieval/transmission options.
Specifications
The system contains an absolute water level sensor with a cable and an automatic data logger with the required data retrieval/transmission options. The data logger is programmed to automatically store the water head/pressure data at fixed intervals with a minimum scan/upload interval from 5 seconds to 168 hours with different options to download the data. Data transmission can be set remotely at scheduled times with telemetry (GSM/GPRS or satellite) or downloaded on a laptop/mobile in the field through Bluetooth or a cable. The water level data can be modified for specific gravity variations in water.
This unit monitors water levels at remote locations continuously in near real time from a central location and also sends alerts through SMS and E-mail. This solution gives researchers and decision maker quick access to the comprehensive groundwater data efficiently and cost effectively.
