Author: Environment Agency - National Centre for Environmental Monitoring and Surveillance
Document Type: Monograph
A prototype water quality monitoring system was developed at the Twerton Office, Bath in 1987, it was designed to monitor and log water quality parameters and transmit them back to a remote personal computer using a cellular telephone. Sherlock is a river bank-side automatic monitor and sampler. Merlin is the same system that floats mid stream of a river or for use in estuaries. The initial prototype was developed by the Wessex Water Authority Catchment Control Function prior to the formation of the NRA. A water quality sampling system was developed by Roman Environmental Instruments (REI) in 1989 to farther enhance the Sherlock system. REI were paid 1000 for the IPR of the sampling system and the embedded software to run it and this now remains the property of the NRA/EA. The NRA/EA own and possess the circuit diagrams, flow diagrams and programs for the sampler hardware and software.
