Liquid Controls steel-case MS-Series rotary motion positive displacement (PD) meters offer the ultimate in flow measurement accuracy for bulk custody transfer of petroleum products, aviation fuels, LPG, crude oil, petrochemicals, and a broad range of industrial liquids. MS-Series meters incorporate a unique design, presenting minimal intrusion in a flowing stream of liquid, as well as minimal pressure drop through the meter.
Liquid Controls MS-Series meters consist of an outer spherical steel-case shell with flanged inlet and outlet ports. The shell houses a traditional LC metering element that employs three rotating and synchronized rotors. These rotors accurately segment flow into a precise volume of liquid for each revolution, with no metal-to-metal contact inside the measuring chamber. Hydraulic sealing between the rotors and the measuring chamber wall is accomplished by a stationary boundary layer of liquid—not by the wiping action of mechanical parts—thereby ensuring sustained accuracy, long service life with minimal wear, and low-pressure drop suitable for operation on gravity low or pump pressure.
All MS-Series spherical shells are constructed of steel. Epoxy coated versions are available for aviation applications. Metering elements are available in metallurgies and seal materials suitable for a wide range of petroleum, petrochemical, and industrial applications.
