The SMC ALBRPD flowmeter features two precisely machined rotating members known as helical rotors which rotate and mesh within the meter’s interior housing in order to form a measuring chamber of known volume which may be used to accurately determine volumetric flow rate as a function of the rotors’ velocity. The helical rotors’ motion is transmitted to the display via a sealed coupling & drive system that enables the display to provide accurate data for both flow rate and total accumulated flow. The unique helical rotor design provides a number of advantages over traditional gear-type PD meters including reduced pressure drop, the virtual elimination of down-stream pulsations, enhanced particle tolerance, and reduced maintenance. The advantages provided by the helical rotor make the ALBRPD an ideal choice for many applications including oil-in-water media and fluids with small amounts of entrained solids
