  • METERING DEVICE AND PARTS THEREFOR
    Publication number: 20150102941
    Abstract: An industrial meter has wireless communication circuitry for communicating with a remote communication device. A repeater device allows the wireless communication circuitry of the industrial meter to continue to communicate with the remote communication device when the meter device is positioned in a location where direct communication between the wireless communication circuitry and the remote communication device is not possible (such as for example when the industrial meter is located underground).

  • Electromagnetic flow meter
    Patent number: 7508222
    Abstract: A method of determining the inter-electrode or electrode-to-ground impedance or the filling state of an electromagnetic flow meter having flow sensing electrodes connected to an electrode signal amplifier, the method comprising applying a test input signal to the flow sensing electrodes via a connection through which an output flow measurement signal of the flow meter is transmitted from the amplifier, in a manner such that the output of the amplifier is indicative of the said impedance or the filling state.

  • Flow sensing in multiple conduits
    Patent number: 7203605
    Abstract: A method of obtaining a plurality of measures of quantity of a substance flowing through a respective plurality of conduits is disclosed, wherein each of the conduits is supplied from an upstream common source location. An improved series of measurements are derived from an upstream absolute measure and downstream relative measures.

  • Flow metering
    Patent number: 6865495
    Abstract: In order to reduce the influence of fluid velocity on a measurement of a concentration characteristic of a fluid, the magnitude of an r.m.s. signal V derived from a voltage induced in a sensor provided in relation to the fluid passage is adjusted using a factor dependent upon the measured velocity v of the fluid. Consequently, the accuracy with which the mass flow rate M of the solids in the fluid can be determined is improved.
