Twin Lube Flow meters belong to the group of Positive displacement Flow meters. The SMOOTH Flowmeter consists of two precisely machined rotating units known as Twin Lobe Rotors which rotate and mesh within the meter’s interior housing.
These 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 low friction lobes are mounted inside the housing by using ball bearings. Liquid Flow causes the rotor to rotate and passes through the device in an axial direction. In so doing, self-contained part volumes are formed which are continuously lled and emptied.
This principle of measurement causes no pressure and/or Flow pulsations. A sensing wheel attached to the measuring rotor is scanned by one non-contact sensor. All moving parts are lubricated by the measurement medium.
