MA Series

Liquid Controls MA Series rotary motion positive displacement (PD) meters offer the best in measurement accuracy for custody transfer of LPG products.
LC meters present a unique design, almost nullifying the stream shear action, balancing pressures in the meter chamber, ensuring an insignificant pressure drop through the meter. LC meter consists of a housing in which three synchronized rotors turn with no metal-to-metal contact neither between them nor with the housing internal surface, preventing the internal parts from wear, which results in a long lifetime.
The hydraulic sealing is accomplished by a stationary boundary layer of liquid, not by the wiping action of mechanical parts.

Main Features

  • High accuracy and repeatability.
  • Low pressure drop: the meter will work accurately both by gravity or under pump pressure.
  • Sustained accuracy: no wear from metal-to-metal contact inside the measuring chamber means almost no accuracy loss over time, fewer recalibrations, and longer lifetime. MA series meters comply with MID (European W&M standard) and other International Weight and Measures accuracy requirements.
  • Weights & Measures approval (world-wide) for custody transfer with mechanical or electronic registration systems meeting API standards.
  • Designed and approved for ATEX Zone 1 Standard.
  • Wide temperature range: products can be metered accurately from -25°C to +55°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: the right-angle design provides unequalled mounting flexibility to meet your installation requirements.
  • Rated to 350 PSI/25 bar for LPG.

Material of Construction

  • Meter and rotors: Cast aluminium (or AISI 316 for class 8 M7 meter).
  • Internal components: aluminium, Ni-Resist, stainless steel, iron.
  • Seal materials: NBR, FKM, PTFE.
