Petrol instruments technology is based on two floating type rotors synchronized by means of timing gears out of the measuring chamber that provide “no metal to metal contact” between the parts composing the “base volume” which is therefore not subject to wear.

This ensures:
•superior performances in terms of repeatability, accuracy and stability with time
•longer life and very low maintenance with minimum operating costs
•no lost of synchronization in case of few solid particles in the liquid
•very low pressure drop
•better performances on very viscous liquids
The constant attention paid to quality, accuracy and adaptation to market requirements have led Petrol Instruments PD flowmeters to be approved for fiscal applications in many foreign countries, to be part of the major vendor list all over the world and to be suitable in any different industrial fields up to the heaviest operating conditions such as
•high viscosity up to 50.000 cP
•high pressure up 150 bar
•high temperature up 250 °C
•aggressive liquids measured with stainless steel and plastic versions when needed

We are proud to say that PETROL INSTRUMENTS is one of the few manufacturers in the world of double case PD flow meters totally manufactured in stainless steel, duplex or bronze.
