OSIL Buoy to Monitor Hong Kong's Largest Reservoir
The largest reservoir in Hong Kong's water supply will be monitored by a buoy from UK-based Ocean Scientific International Ltd. (OSIL), the company announced today.
Euro Tech (Far East) Ltd. has purchased a specialized 1.2 meter Shearwater buoy from OSIL for installation in Hong Kong's High Island reservoir. The buoy will measure DO, pH, turbidity and chlorophyll in the reservoir, which holds 281,124,000 cubic meters, the largest capacity of Hong Kong's 16 reservoirs.
The instrumented buoy features an internal electronics canister that houses a Campbell Scientific CR1000 datalogger and GPRS modem for data transmission. A separate canister holds two 33Ah batteries.
A stainless steel top frame accommodates three 36W solar panels, together with a 6Db antenna, 1NM navigation light, and radar reflector. The 50 meter mooring has been designed by OSIL to accommodate two Hydrolab DS5X sondes, one at a five meter depth, and one at 15 meter depth.
