FLUSSIMETRI IN DERIVAZIONE A DIAFRAMMA ORIZZONTALI

HORIZONTAL DIAPHRAGM TEE JOINT FLOWMETERS “OP”

The OP flowmeter is compacted, light and cheap, with the visual part of the measure range in a piece of transparent and shockproof plexiglas, it is lent where is required the control and the measure of great ranges in small spaces. It’s suitable only for horizontal pipe. The maintenance and the cleaning of the plexiglas measurer (not corrosion subjected) is particularly easy. The series “OP” flowmeters are suitable for treatment waters plants, fireproof groups pressurization, wine-making plants, thermotechnical plants, etc.. These flowmeters are suitable to be inserted into flanges, in confirmity to the normative UNI.
