Abstract
A combined driver and pick-off sensor component (200, 300) for a vibrating meter is provided. The combined driver and pick-off sensor component (200, 300) includes a magnet portion (104B) with at least a first magnet (211). The combined driver and pick-off sensor component (200, 300) further includes a coil portion (204A, 304A) receiving at least a portion of the first magnet (211). The coil portion (204A, 304A) includes a coil bobbin (220), a driver wire (221) wound around the coil bobbin (220), and a pick-off wire (222) wound around the coil bobbin (220).
Claims20
A combined driver and pick-off sensor component (200, 300) for a vibrating meter, comprising:
- a magnet portion (104B) comprising at least a first magnet (211);
- a coil portion (204A, 304A) including:
- a coil bobbin (220);
- a driver wire (221) wound around the coil bobbin (220);
- and
- a pick-off wire (222) wound around the coil bobbin (220), wherein the driver wire (221) and the pick-off wire (222) are separate and distinct.
A vibrating meter (400), comprising:
- a meter electronics (20);
- a sensor assembly (40) in electrical communication with the meter electronics (20) and including:
- one or more flow conduits (103A, 103B);
- and
- one or more combined driver and pick-off sensor components (200, 300) coupled to at least one of the one or more flow conduits (103A, 103B) with each of the combined driver and pick-off sensor components comprising a magnet portion (104B) and a coil portion (204A), wherein the coil portion (204A) includes a coil bobbin (220), a driver wire (221) wound around the coil bobbin (220), and a pick-off wire (222) wound around the coil bobbin (220), wherein the driver wire (221) and the pick-off wire (222) are separate and distinct.
A method for forming a vibrating meter including a sensor assembly with one or more flow conduits, comprising steps of:
- winding a driver wire around a coil bobbin;
- winding a pick-off wire around the coil bobbin, wherein the driver wire and the pick-off wire and separate and distinct;
- coupling the coil bobbin to one of the one or more flow conduits;
- electrically coupling the driver wire to a meter electronics for communicating a drive signal;
- and
- electrically coupling the pick-off wire to the meter electronics for communicating a pick-off signal.
