The flow indicator is a protective device which checks that a given flow of aliquidina pipe system is the desired rate.
The indicator can also be used for control purposes often in combination with float switches for stopping and starting pumps.
The scale on the indicator is graduated in litres/min. A make and break contact is actuated when the flow rate of the liquid deviates from the set value. This contact can be used, for example, for switching on a warning lamp or an acoustic signal,or for starting or stopping pumps.
The indicator is designed for installation in the piping system and no holes are required in the pipe wall for the sensing body.
The indicator can supervise the flow of coolant In transformers, induction coils of furnaces, generators, diesel engines and compressors. It can supervise thesupply of fuel oil to central heating boilers and lubricating oil to gear units and bearings, or the flow of liquids In a water treatment plant.
It can cope with almost anything that flows, high and low viscous liquids, contaminated or clean, from small quantities ot 0,5 litre per minute to large quantitiesof more than 10000 litres per minute.
