Durable and accurate metering units for monitoring the amount of petrol dispensed. Our range includes the Piusi K33 ATEX approved 3 digit mechanical flow meter. Fuel dispensing equipment used within flammable environments is required to have special approval to be classifed as safe for use. Petrol has a higher flashpoint than diesel, and therefore flow meters used with petrol are required to be ATEX certified. As well as being used for petrol, these units can also be used with diesel and oil within a zone 1 area.
