LectroCount™ LCR-II

Liquid Controls produces among the most reliable and accurate metering systems available, worldwide. For truck-mounted or fixed-site custody transfer applications requiring Weights & Measures-approved accuracy, LC products deliver consistent, error-free, dependable service.  Liquid Controls family of LectroCount electronic registers provide:

  • Improved efficiency relative to mechanical systems
  • Electronic temperature compensation
  • Weights & Measures approvals
  • Ruggedness and reliability
  • Simplicity of operation
  • Compatibility with mobile computing solutions such as the DMS


Features and Benefits of Electronic Registration:

  • Muti-point calibration to improve the accuracy over a wide flow range
  • Electronic Temperature Volume Compensation (ETVC) to reduce lost volume
  • Increased security
  • Future expansion and modularity with RS232/485 communcation
  • Greater control and accuracy of the delivery system through use of two stage valves, optical air eliminators with a LectroCount register as a central control unit
  • Lower total cost of ownership through fewer moving parts, solid state electronics and longer MTBF (Mean Time Between Failure).

LectroCount™ LCR 600
DMS Mobile Computing System


REPEATABLILITY: Capable of .03% of reading over entire range.
LINEARITY: Capable of ±0.10% or better over a 5:1 range from maximum nominal meter capacity.
LINEARITY: Capable of ±0.10% or better over a 10:1 range from maximum nominal meter capacity.
LINEARITY: Capable of ±0.15% or better over a 40:1 range from maximum nominal meter capacity.

Due to the capabilities of multi-point calibration for meters equipped with LectroCount™Electronic Registration, superior accuracy (linearity) can be provided as indicated above.

NOTE: Accuracy obtainable when all variables remain constant. Reading/ measurements must be equal to a minimum of one minute of flow at selected rate(s). All accuracy statements based on metering Stoddard Solvent, approximate viscosity 1 CPS. On higher viscosity products, the average deviation in accuracy will be even less.
