Monitor water levels in multiple tanks remotely using submersible sensors and GSM technology. Configure alarms for high/low levels and receive alerts via SMS or email.
The IMTG submersible level sensor, combined with the RamBox-B signal conditioning and GSM communications unit, offers a reliable and cost-effective solution for remote water tank level monitoring. This system is particularly well-suited for applications with multiple tanks spread across a wide area, such as those found in agricultural irrigation, water distribution networks, and industrial process control.
The IMTG sensor utilizes a pressure-based measurement principle, where the hydrostatic pressure exerted by the water column is directly proportional to the water level. This pressure is converted into a 4-20mA analog signal, which is then transmitted to the RamBox-B unit. The RamBox-B provides signal conditioning, converting the 4-20mA signal into a digital value that represents the water level. This unit also features a built-in GSM modem, enabling it to transmit the level data wirelessly to a remote monitoring station via the mobile network.
One of the key advantages of this system is its ability to trigger alarms based on predefined level thresholds. Users can configure the RamBox-B to send SMS alerts or email notifications to designated personnel when the water level in any of the tanks reaches a critical high or low point. This allows for timely intervention, preventing potential issues such as overflow, pump damage, or supply disruptions.
The system’s modular design offers flexibility in installation and configuration. The IMTG sensor can be easily submerged in the tank, while the RamBox-B can be mounted remotely in a suitable location with access to the GSM network. This eliminates the need for extensive wiring and allows for easy integration into existing infrastructure.
Furthermore, the use of GSM communication ensures wide area coverage and reliable data transmission, even in remote locations with limited internet connectivity. This makes the IMTG and RamBox-B combination an ideal solution for monitoring water tanks in areas where traditional wired or radio-based systems may be impractical or cost-prohibitive.
