2 escription The KOBO MH flowmeter is used to measure and monitor the volume flow rate of fluids, pulps, pastes and other electrically conductive materials, without loss of pressure. When an electrically conductive medium passes through a directional magnetic field, a voltage is induced in accordance with Faraday s aw of Induction. The size of this measurement voltage is proportional to the mean rate of flow and consequently also to the volume flow rate. flowmeter consists of a sensor that picks up the measuring signal generated from the induced voltage, and a transducer that converts this signal into a standardised output signal (4-20 m or pulses). The measurement transducer can be affixed to the sensor or mounted separately. Pressure, temperature, density and viscosity do not affect the volume measurement. Solid fractions and gas bubbles should be avoided. The significant properties exhibited by MH include: Great choice of linings O O Stainless, Hastelloy, tantalum or platinum electrodes Wide variety of process connections Can be used in rough ambient conditions Fields of pplication cids, alkalis Pastes rinking water, waste water etc. Technical etails djustable measuring range terminal values: m /s Minimum conductivity: 5 µs /cm (for fluids in general) 20 µs/cm (demineralised water) ccuracy: ±0.3% of read. ± 0.01% x Q max Repeat accuracy: ±0.15% of read. ± 0.005% x Q max (reference conditions: water, measured medium temperature of 22 C ±4K, ambient temperature 22 C ±2K, inlet path 10 x, outlet path 5 x, Q max at 10 m/s) Process temperature: C (hard rubber, soft rubber) C (PTFE); PF C (E-CTFE) mbient temperature: C, depending on process temperature Rated pressure: PN 40, (40 bar) (½"-12") PN 16, (16 bar) (½"-24") PN 10, (10 bar) PN 6, (6 bar) higher pressures on request Sensor materials inings: Hard rubber, soft rubber, PTFE, PF, E-CTFE Electrodes: Stainless, Hastelloy C4, tantalum, platinum, earth ring and other materials on request Housing: Enamelled (MH-1,MH-2, MH-5) stainless (MH-6) Process connection: Steel or stainless flange EN1092 and SME B16.5, wafer version, foodstuff, screw seal IN11851, Tri-Clamp, other connections on request Nominal sizes: other nominal sizes on request Protection type: IP 67, IP /
