POSITIVE DISPLACEMENT METERS
FOR CUSTODY TRANSFER OF VALUABLE LIQUIDS AND FUELS

THE ORIGINAL TRI-ROTOR METERPROVEN MOST TRUSTED AND RELIABLE SINCE 1956

32132132132

The original Liquid Controls tri-rotor meter design consists of a
housing in which three rotors turn and measure fuel in synchronized
relationship with no metal-to-metal contact.
The bladed displacement
rotors (1 & 2), alternately
rotate through the halfcylinder bores of the meterelement, while the single
blocking rotor (3) rotates
within its bore to producea continuous capillary seal
between the unmeteredproduct and the meteredproduct.
Because the force exerted by the fluid flowing through the meteris at right angles to the faces of the displacement rotors, and therotor shafts are always in a horizontal plane, there is no axial thrust,
thereby eliminating wear between the rotors and the bearing plates
and ultimately providing a lifetime of measurment accuracy.
