COMMON CONFIGURATIONS

MA-series-family.153-v.3-labeled
FEATURES
  • 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 350psi / 24 BAR.

    • Over 10:1 range
      Mech. registration: capable of ±0.22% or better from max. nom. flow rate
      Elect. registration: capable of ±0.10% or better from max. nom. flow rate
    • Over 40:1 range
      Mech. registration: capable of ±0.5% or better from max. nom. flow rate
      Elect. registration: capable of ±0.15% or better from max. nom. flow rate
  • Temperature range:
    -40º F to 160º F (-40º C to 71º C)
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.
