Flowmeters

“PETROL” PD Flowmeters are typical volumetric instruments which directly measure the quantity of flowing liquid by means of a couple of rotors. These instruments, totally manufactured in Italy since more than 40 years, allow an accurate measurement either of the flow rate either of the volumes flown (integrated flow rate) of practically all the liquids industrially utilized. They may be used for custody transfer purposes, operating controls and for the many other needs of the petroleum, chemical, pharmaceutical industry, etc.
