It has always been a challenge when it comes to centralised monitoring the water level of the water tank or oil tank and also can remote control of water pump stations, dams and reservoirs within the area. However, advancements in GSM technology now make it possible to utilise the GSM networks as a wide area communications platform for telemetry applications. The system has proved the perfect communications platform for covering the vast distributed water network. Engineers have taken advantage of this technology and have implemented the first GSM telemetry application at a new booster pump station.

All communications between the remote pump unit, tank unit and wireless monitor/control unit is continuously monitored to ensure reliable ongoing operation and instant notification if something is not operating correctly.Automatic water level and pump unit monitoring and remote control system with SMS message notification direct to your mobile phone. From remote cell phone it is also possible to request an information from device. Device information readings will come as one or several messages.

You you can use the mobile phone or PC software to config the device easily.
