The OCD CW is a low cost solution for simple cooling water monitoring applications, designed for monitoring engine cooling water and fresh water systems. The system is widely used in refineries and power stations when discharging their cooling water to local rivers and the sea. Boiler condensate can also be monitored with the addition of a cooler.

With solids discrimination up to 50ppm the OCD CW provides repeatable accurate monitoring and can also be used in industrial waste water applications
