Liquid Controls - Model MA Series -Rotary Motion Positive Displacement (PD) Meters
FromSAMPI S.P.A.
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.

- 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.
- 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.
