Liquid Control M and MA Series rotary motion positive displacement (PD) meters offer the ultimate in measurement accuracy for custody transfer of petroleum productd, aviation fuels, LPG and a broad range of industrial liquids. LC meters incorporate a unique design, presenting minimal intrusionin a flowing stream of liquid, as well as minimal pressure drop through the meter.
The LC meter consist of a housing in which three synchronized rotors turn with no metal-to-metal contact. Hydaraulic sealing is accomplished by a stationary boundary layer of liquid, not by the wiping action of mechanical parts.
Meters provide exceptionally accurate service when using Liquid Controls; unique positive displacement matering principle, even under variable operating conditions (changes in temperature, pressure and viscosity). Provides the nergy efficient and functional performance desired from an economical volumetric measuring instrument. Available eith traditional mechanical seal or glandless magnetic driven pulse output device. A wide range of accessories are available to meet almost every metering need.
- High accuracy and repeatability
- Low maintenace, no metal-t-metal contact in measuring chamber
- Aluminium materials of construction
- Sel-contained without electrical power or signal conditioning (for units equiped with mechanical registers, printers or presets) no special piping requirements
- Electronic output and registration equipment where enhanced accuracy and electronic communications are needed
- Weight & Measures approval (world-wide) for custody transfer with mechanical or electronic registration system meeting API standards
- Electronic accessories designed and approved to Class 1 Div. 2 standards
Superior performance features
low pressure drop-will operate in 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 an International Weight and Measures accuracy requirements
Wide temeperature range-Product can be metered accurately from -40°F (40°C) to 160°F (71°C)
Wide viscosity range-LC meters can accurately meter product 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/ fitting provides unequaled mounting flexibility to meet your installation requirements
Performance Specifications
Liquid Controls positive displacement meters are engineered to provide accurate performance and a long trouble free service life requiring minimal miantenance with few replacement parts. The unique cast-case construction of the M and MA Series meters results in low pressure drop for most liquids, delivering superior performance and minimal demand on system pumps. The exclusive LC metering element eliminates inaccuracies due to clearance cahnges, minimizes loads on bearings, eliminates axial thrust and perform with equal accuracy for forward or reverse flow. M and MA Series meters compact design and multiple inlet/ outlet flange confirgurations provide unmacthed mounting versatility.
