M-Series Positive Displacement Flow Meters

Liquid Controls M-Series rotary motion positive displacement (PD) meters offer the ultimate in measurement accuracy for custody transfer of petroleum products, aviation fuels, LPG, and a broad range of industrial liquids. LC meters incorporate a unique design, presenting minimal intrusion in a flowing stream of liquid, as well as minimal pressure drop through the meter. The LC meter consists of a housing in which three synchronized rotors turn with no metal-to-metal contact. Hydraulic sealing is accomplished by a stationary boundary layer of liquid, not by the wiping action of mechanical parts.

  • Low pressure drop — will operate on gravity flow or pump pressure.
  • Sustained accuracy — no wear from metal-to-metal contact inside the measuring chamber means minimal deterioration in accuracy over time, fewer recalibrations, and longer service life. Meters conform to NIST and International Weights and Measures accuracy requirements.
  • Wide temperature range — products can be metered accurately from -40° F (-40° C) to 160° F (71°C).
  • Wide viscosity range — LC meters can accurately meter products from less than 30 SSU (less than 1 centipoise) to 1,500,000 SSU (325,000 centipoise).
  • Maximum adaptability — right angle design with choice of stock or custom elbows/ fittings provides unequaled mounting flexibility to meet your installation requirements.
  • Rated to 150psi / 10.5 BAR.

MS-Series Positive Displacement Flow Meters

MS, MSAA, MSA, MSB and MSC Steel Case Meters

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.
