2. Overview
The GF630/LF600F, GF630/LF610F and GF632 electromagnetic flowmeter can be use in the
following hazardous (classified) locations.
ClassⅠ, Division 2, Groups A, B, C and D,
ClassⅡ, Division 2, Groups E, F and G
ClassⅢ
The GF630 and GF632 electromagnetic flowmeter measures the volumetric flow rates of electrically conductive
materials on the basis of Faraday's Law of electromagnetic induction.
The device consists of two units: the GF630 and GF632 detector, through which the fluid to be measured flows,
and the converter, which receives the electromotive force signals from the detector, then converts the
signals into the 4–20 mA
dc signal.
Features
Every type of electromagnetic flowmeter has the following features:
Fluid flow is not obstructed and pressure loss is negligible.
The process fluid's temperature, pressure, density or flow conditions has no effect on the accuracy of the
flowmeter.
The flowmeter output is directly proportional to the process flow rate, thus it is easy to read its output.
