  • Patent number: 9784603
    Abstract: A magnetic flowmeter includes a conduit and an electrical coil for generating a magnetic field extending through the conduit. A coil driver is configured to energize the coil and generate a periodically reversing magnetic field. Electrodes are arranged to detect voltages generated by flow of a conductive fluid through the magnetic field. A measurement system measures fluid flow rate using voltages detected by the electrodes. An empty conduit detector receives signals from the electrodes and determines whether or not the electrodes are immersed in the conductive fluid by analyzing the signals from the electrodes. The flowmeter optionally includes a low-flow verification system for distinguishing true low or zero flow rate measurements from measurements caused by the electrodes being exposed above the fluid level in the conduit by assessing whether or not EMF induced by magnetic flux change can be detected.

  • Patent number: 9778081
    Abstract: A paddle wheel flow meter designed for measuring the flow rate of a viscous or debris-laden fluid with fewer parts, higher durability and simplicity of servicing. The flow meter includes a housing including a flow bore and an insert body with an integral rotor shaft. The insert body is removably insertable into the housing. A rotor includes rotor blades and is attached to the rotor shaft so as to be at least partially located in the flow bore such that flow of the fluid causes the rotor to rotate. A sensor unit generates a signal indicative of the rotational rate of the rotor, which can be used to determine the flow rate of the fluid.

  • Patent number: 9778281
    Abstract: Assessing and removing jitter from tachometer signals enhances the performance of condition monitoring systems where accurate tachometer signals are needed. A system as disclosed herein can be designed and configured to have a low order of operations, so as to allow for implementation on low cost microcontrollers, which can be important for bused, distributed monitoring systems in which the tachometer zero crossing data is collected at a tachometer sensor and then broadcast to other remote sensors needing that information for vibration or other advanced analysis. Moreover, for monolithic architecture systems (e.g., a centralized processing and control architecture), the low order of operation and small software code base allows the system to be a simple/low cost addition to existing monitoring systems.
