Troll 9500 Water Quality Monitoring for Remote Locations using GSM/GPRS Telemetry

Saturday, July 12th, 2008

Troll-Link1-sm.jpgRS Hydro have recently won two seperate contracts to supply anWater Quality Sonde with Remote Monitoring Telemetry Troll Link Systemd install the Troll 9500 multiparameter water quality sonde in remote locations in Wales. Two further units are being supplied as stand-alone platforms.

The clients are using the Troll 9500 XP Professional platform along with the Troll Link solar powered telemetry system with plug and play sensors including turbidity, level, temperature, conductivity and pH/ORP. One of the clients is using the Troll 9500 to provide an early warning alarm to inform the client if any of their remedial works on a dam face are having an influence on the water quality of the compensation flow from the reservoir. The other client is using 4 units to measure water quality in a Site of Special Scientific Interest (SSSI) over a period of two years.

Both clients are using RS Hydro’s FlowView platform to provide all the data on a daily basis. Should any of the alarm thresholds be exceeded, text (SMS) messages will be sent direct to the client. It is possible to view a demo of the Troll 9500 on our local river. Before you think there are errors in the conductivity readings, they are correct! The Salwarpe RIver is partly fed by Droitiwch Spa’s naturally occuring brine baths, hence at low flows, conductivity rises dramatically.
