Liquid Controls steel-case MS-Series rotary motion positive displacement (PD) meters offer the best in flow measurement accuracy for bulk custody transfer of petroleum products, and aviation fuels. MS-Series double case unique design provides the same advantages of M/MA series meters but at higher flow rates and with an internal hydraulic balance which further reduces wear and allows a service-free working time of some year decades.
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 meter element provided with 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.
All MS-Series spherical shells are constructed of carbon steel. Epoxy coated versions are available for aviation applications, when further product filtering is not available. Meters parts are available in metallurgies and seal materials suitable for a wide range of petroleum, petrochemical, and industrial applications.
