  • Patent number: 10209108
    Abstract: A flow measuring device for measuring flow of a fluid. A housing has a passage which extends between an inlet and an outlet. A shaft is disposed within the housing and is rotatable about a central axis. A flow detector is mounted on the shaft and disposed at least partially within the passage. The flow detector includes a rotatable, generally cylindrical body that rotates about a central axis as the fluid flows. A magnet is disposed within the housing such that the central axis extends through it, and is configured to rotate simultaneously with the body about the central axis. A magnetic encoder is disposed within the housing and configured to sense rotation of the magnet as the flow detector angularly displaces about the central axis so as to detect angular displacement of the flow detector.

  • Patent number: 9683697
    Abstract: Methods and systems for determining lubrication flow dispensed to lubrication points. Lubricant delivery is determined based upon the difference between volume measurements detected as the lubricant is delivered to the lubrication points, and volume measurements detected as the lubricant is vented after delivery. A flow sensor in the lubricant supply line measures lubricant delivered and lubricant vented and a controller determines the amount dispensed based upon the difference between the delivered and vented measurements.

  • Patent number: 9388940
    Abstract: Apparatus and method for supplying lubricant to a plurality of lubrication sites. Embodiments include a pump with venting and non-venting piston return, a pump with stirrer and direct feed mechanism, a pump with CAN system and self-diagnostics, a pump with heated housing and reservoir and a pump with stepper motor and overdrive control. Profiles drive the stepper motor at various speeds.

  • Patent number: 9222618
    Abstract: Apparatus and method for supplying lubricant to a plurality of lubrication points via divider valves. A pump driven by a stepper motor to supplies lubricant at a varying rate which provides lubricant substantially uninterrupted at the lubrication point(s), and/or provides lubricant at a continuous non-constant flow rate which provides lubricant without interruption at the lubrication point(s), and/or provides lubricant at a constant flow rate which provides lubricant without interruption at the lubrication point(s).
