M-Series

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.

  • Sustained Accuracy

    No 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.

  • High Pressure rating

    Rated to 150psi / 10.5 BAR.
