In one of our previous application notes we showed you how SMS well to tank control works. This one on the other hand will show you how that is done via GPRS using GT900 line of products. Our GT900 line can operate in different modes – GPRS Router, SMS Reporter, SMS Gateway. Further text will show you the GPRS Router function.

It is a very common situation that you have well with pump on one location, and water reservoir on a completely different, remote location. These locations are usually on inaccessible terrains, and it would be very expensive and inefficient that workers check manually levels of water in tank. Also, if you would try to refill reservoir on a hunch you are facing two problems – because consumption is not linear, and depends on circumstances, you could possibly have situations that your tank is empty for periods of time, and also that you are overfilling it on the other.
This version of DECODE solution will consist of devices from GT900 family, but this time in GPRS Router mode. Main difference is that this kind of configuration gives you possibility to control whole system from one center (point to multi-point). Also you can make smaller circles of regulation between devices on locations, under the supervision of device in control center. Big advantage of our routers is that all routing can be done directly on the device. You can set up devices using our free GSM Utility software. In this kind of communication you have constant flow of data, opposed to SMS Reporter where data is send periodically. All you need are SIM cards in VPN.
