LC M-Series & MSAA-Series Meters
Liquid Controls positive displacement (PD) flowmeters provide the industry’s most time-proven record of superior accuracy, performance, and long-term durability in custody transfer of refined and alternative fuels.
Simplicity of design and construction, together with sustained accuracy is why customers prefer Liquid Controls meters in a variety of fluid custody transfer applications throughout the world.
- 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.

Stated accuracy obtainable when all variables remain constant. Reading/ measurements reflect a minimum of one minute of flow at selected rate(s). All accuracy statements based on metering safety solvent (aliphatic hydrocarbon), approximate viscosity 1 CPS. On higher viscosity products, the average deviation in accuracy will be less.

METER FLOW RATES vs. VISCOSITY
Use the chart below to determine maximum meter flow rate relative to meter bearing material and product viscosity:
- Determine the percent of rated capacity at which the meter will be required to operate;
- Determine product viscosity at system operating temperature;
- Plot the point on the chart where the two lines intersect;
- Determine the meter bearing material from construction/application table above and locate the corresponding slope on the chart.
If the plotted point is above the bearing material slope, you are outside the allowable pressure loss for the specified meter and bearing. You should either chose a larger meter, reduce flow rate, or consider alternative bearing materials.
