Yokogawa OpreX CA Series magnetic flowmeters

Yokogawa has announced the release of the OpreX CA Series magnetic flowmeter, which succeeds the ADMAG CA Series and is being released as part of the OpreX field instruments range.

The capacitance-type magnetic flowmeters utilise electrodes mounted outside a ceramic measurement tube to measure the electromotive force generated by fluids passing through the tube, eliminating all direct contact between the electrodes and the fluid. In addition to this non-wetted electrode construction, the meters offer support for the widely used HART communications protocol and a choice of nine languages is now given for the user interface. As an optional feature, measurement data can be saved on a microSD card for viewing on a PC, and instrument setting data that is saved on a microSD card can be copied to other devices. The display is now equipped with a backlight function that improves visibility at night and in dark locations.

The flowmeters are also equipped with a function that can analyse and verify that they are in sound operating condition while mounted on a pipe. Inspection of magnetic circuits, excitation circuits and arithmetic circuits, and the checking of device status alarms and soundness, can be performed in 6 min.

Measurement tubes in eight sizes ranging from 15 to 200 mm are available for use with the flowmeters, suiting a wide range of purposes. As they have the same face-to-face lengths as the ADMAG CA Series flowmeters, no additional work is required for in-place upgrades.
