Design Features

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 or stainless 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.
