Abstract: A flowtube assembly for a magnetic flowmeter is provided. The flowtube assembly includes a flowtube configured to receive a flow of process fluid therethrough. A magnetic core is mounted relative to the flowtube and includes a stem extending from the flowtube to a pair of arms. Each of the arms extends away from the stem. A spool having a plurality of magnetic windings is disposed about the stem and spaces the plurality of windings from the flowtube.

Abstract: An optical isolator is provided. The optical isolator includes a printed circuit board having a first surface and a second surface opposite the first surface. The printed circuit board has a recess extending only partially through the board. The first photoelement has an active surface and is mounted relative to the first surface of the printed circuit board. A second photoelement has an active surface and is mounted relative to the second surface. The second photoelement is configured to interact with the first photoelement. At least one of the first and second photoelements has its active surface disposed at least partially in the recess. A portion of the printed circuit board is interposed between the first and second photoelements.

Abstract: A magnetic flowmeter includes circuitry for sensing coil current, coil voltage, or coil resistance. Based on the sensed coil current, voltage, or resistance, a digital processor determines whether a power limit or a coil current limit is exceeded and either halts operation until it receives a new configuration with a new coil current setpoint, or determines a new coil current setpoint itself and adjusts the magnetic flowmeter to that new coil current setpoint.
