Remote monitoring and automatic water tank level control

This remote control system implements the function of automatically activating the pumping stations based on the water level detected in the reserve tanks, in order to keep it constant within the set set point and hysteresis parameters. It is useful in the frequent cases in which the distances between pumping stations and collection tanks are considerable and do not allow economically advantageous wired connections.

The system described, SENTINEL LINK implements the automatic control of the pumping stations based on the detected water level, with bidirectional communication between the two control units.

The SENTINEL LINK, implemented by 2 twin RCU8951 units, is a dynamic water level management system that detects water level changes and automatically controls the lift pumps. The remote water level management and control system performs the following operations in a fully automated mode:

1) When the level drops below the minimum threshold, SENTINEL-LINK 1 sends an SMS to SENTINEL-LINK 2 to command the turning on of the water pump. When the water pump turns on, the SENTINEL-LINK 2 sends a notification SMS to administrators to inform them of the water pump turning on. For example: “Water pump 1 on”

2) When the pump brings the water level above the maximum threshold, SENTINEL-LINK 1 sends an SMS to SENTINEL-LINK 2 to command the water pump to turn off. When the water pump is stopped SENTINEL-LINK 2 sends a notification SMS to the administrators to inform them of the water pump being turned off. For example: “Water pump 1 shutdown”

Possibly, administrators can take manual control of the system and send command SMS to the pumps which cancel and/or integrate those generated by the automatic control system.

If, in open-air reservoirs, changes in weather conditions such as drought, rain or dam level changes affect reservoir water levels, the SENTINEL-LINK remote monitoring and control system can detect the changes water levels and send relevant notifications to administrators.

The SENTINEL-LINK system offers convenience and maximum security since administrators can receive notifications anywhere even in places where there is no internet connection available, 2G or 3G or 4G mobile network coverage is sufficient.
