RDL-904S remote monitoring solution is a rugged hardware platform rechargeable battery/Solar powered, meant for logging data from power pressure transmitter and monitors pulses/4-20 mA from an external flow meter. The unit has additional input to read level information through 4-20mA from level transmitter. The solution includes a controller and GSM/GPRS modem, and two additional digital inputs for monitoring. Data is sent to centrally located server through GPRS/GSM at programmed frequency through HTTP format. The data collected can be used to monitor flow and pressure to detect leakages, if any. The unit is powered through external power source.
