6600 Series Magmeter

The Magmeter 6600 is an in-line electromagnetic flowmeter recommended for applications involving conductive liquids or slurries.

Principle of Operation (See Figure 2)

The Magmeter 6600 operates on the principle of electromagnetic induction, applying a controlled electromagnetic field (2) in the metering tube by way of coils (1). Conductive fluid flowing through the electromagnetic field generates a voltage proportional to its velocity. Sensing electrodes (4) on the inner surface of the metering tube detect the induced voltage, which the unit further converts into a volumetric flow rate. The Magmeter 6600 features a noise reduction function, in which a grounding electrode (6) detects ambient noise.
