Measurement of oil and turbidity

The measurement of oil and turbidity is based on the medium sample to be taken that will be fed through the meter and returned back to the process. A light signal will be led through the medium whose refraction with a clean medium is known.

For example, in condensate systems the meter checks the cleanness of the condensate. In many industrial processes where, for example, the product tanks are heated with steam, there is a risk if the heating coils burst up that foreign matter such as oil will flow into the condensate system. If the GESTRA OR oil and turbidity sensor identifies change in the condensate cleanness, it will immediately send the information to the control centre, and the signal will give, for example, to the 3-way valve in the line a command to remove dirty condensate into the reserve tank.

Process safety device

So a situation is achieved where the information about the emergency state is received quickly, and the oily condensate cannot pollute the whole condensate system.

GESTRA OR 42/52 is designed for a continuous control of turbidity, emulsified oil and fat content in liquids.

Its applications include the monitoring of the oil content in the condensate of the steam boiler plants as well as the control of sand filters, reverse osmosis and removal of minerals in the water supply plants.

Other applications are, for example, waste water plants and beverage industry.
