Pulp & Paper

Pulp stock is where ordinary meters foul. A full-bore mag meter — ModMAG M1000 or M2000 — has nothing in the stream to catch fibre and treats pulp stock as a core mag-meter fluid; the Dynasonics DFX reads fibre-laden and aerated streams by Doppler from a clamp-on transducer; and the Preso COIN segmented wedge is the DP element for slurries that foul other primary elements. We match the meter to the stock, the line size, and the straight run you actually have — start at the flow meters page.

Two ways, depending on the line. The Vortex VN2000 comes as an inline meter or a hot-tap insertion version for large steam mains that must stay live; on the DP side, the Preso Ellipse averaging pitot and Preso venturi tubes cover steam and large process lines. See Vortex and Preso.

Yes — the ATi GasSens line is fixed-point detection for toxic and combustible gases in air, and pulp & paper is one of its named application areas. D12 transmitters cover individual monitoring points, and the A14/A11 modular receiver puts mixed toxic and combustible channels on one panel. Details on the ATi GasSens page.

With an Ircon / Raytek MP line scanner from Fluke Process Instruments: the scanner sweeps the moving web to build a full-width temperature profile, and the ES150 application package is the MP-SYS system written for web processes such as paper drying. Start at the Fluke Process Instruments page.

Yes on both. Reuland Electric builds AC wound-rotor (slip-ring) motors for high-inertia process loads like pulpers, using adjustable rotor resistance to manage the starting duty. On the heating side, Indeeco TRIAD unit and area heaters are built for corrosive paper-mill and washdown areas, and Heatrex and Accutherm process-air heater banks serve forced-air drying. See Reuland Electric and the electric heating page.
