Working principle

One helicoidal rotor turns freely inside a cylindrical tube. The working liquid pushes the rotor blades, making them turn at a flow speed which is proportional to the flow rate. A pick-up coil mounted externally receives the propeller turns and generates an electrical signal which, once treated by the different electronic converters, provides: – Flow rate indication – Total or partial volume – Digital and analog outputs (mA, Hz and V)
