Magnetite Meter Applications • Magnetite detection in pipes • Pipe occlusion estimation Overview The Diverse MF500M is a hand held, battery operated Magnetite Meter using a novel magnetic force probe. The instrument may be used to determine the amount of magnetite in cooling pipes. The magnetic detector is housed in a separate stainless steel hand held case providing maximum protection and magnetic transparency. The processor based meter has a user friendly menu driven interface to allow simple operation. The sensor measures magnetic force and this is compensated for gravity effects so that minimal change to the reading occurs for different orientations of the probe. It displays raw data from the sensor, as well as estimates of the amount of magnetite in a given (non-magnetic) pipe. Auto zero can be requested at any time by the press of a single button. Using a measurement rote, either magnetite thickness or sector fill can be estimated. Features ● Measures magnetite effect ● Ideal for use with cooling pipes ● Rugged stainless steel probe ● Auto Zero facility ● Smart instrument able to estimate degree of occlusion ● Measures Magnetite levels ● Digital display ● Audible confirmation ● Selectable occlusion display ● Calibration sample ● Supplied with a protective carrying case and full user instructions Measurements of magnetite force levels are displayed on the unit and can be stored in its internal memory for later recall. Audible confirmation of measurement and zeroing facilitates use in restrictive environment. Supplied with a calibration sample. User can modify pipe occlusion calibration. The Software embedded in the MF500M provides acquisition of the magnetic force extended by the magnetic effect of the magnetite. The force is a measure of the amount of magnetite and its range. This information is used together with the geometry of the pipe (assumed linear with defined diameter and wall thickness) to gauge the amount of occlusion. The force effect is dependent on how the magnetite appears in the pipe. It may be deposited in a similar way to calcite, or appear as broken magnetite. The density reduction of broken magnetite is built into the instrument, so that the degree of occlusion can be inferred for each scenario. The user can modify the pipe occlusion calibration for different pipe wall thickness or magnetite packing density. Settings are stored at power off but the instrument has the facility to revert to t

Magmeter MF500M Magnetite Meter DIVERSE www.diverse-technologies.net About Magmeter MF500M Stainless steel superheated steam and re-heater tubes, operating with high temperature steam for extended periods, develop a two-part oxide layer on the inner bore of the tubes. The magnetite oxide is characterised by two distinct phases which have different coefficients of expansion. The layer closest to the tube centre which is iron rich, and an inner layer which is chrome rich. At metal temperatures of 90C to 150C, the outer layer of magnetite oxide tends to delaminate from the tightly adhering...
