Meter improves measurement efficiency

With a non-invasive, no-moving parts flow sensing technology, the Ultra Mag inline wastewater flow meter from McCrometer delivers measurement accuracy of +0.5% in water effluent with repeatability of +0.05%. The meter measures liquid flow in 50.8 to 914 mm (2¬ to 36 in) lines from 0.06 to 15 mps (0.2 to 49 fps) at pressures of up to 2 mPa (300 psi). It operates in temperatures up to 77°C (170°F).

HEMET, California --With a non-invasive, no-moving parts flow sensing technology, the Ultra Mag inline wastewater flow meter from McCrometer delivers measurement accuracy of +0.5% in water effluent with repeatability of +0.05%. The meter measures liquid flow in 50.8 to 914 mm (2 to 36 in) lines from 0.06 to 15 mps (0.2 to 49 fps) at pressures of up to 2 mPa (300 psi). It operates in temperatures up to 77°C (170°F).

Manufactured with 316 stainless steel, the meter's electrodes feature a unique bullet-shaped design that is self-cleaning for long service and reduced maintenance. Combined with the abrasion and corrosion resistance of the fusion-bonded epoxy UltraLiner, this magmeter is an alternative for hard-to-reach areas and applications where maintenance is awkward or time-consuming.

To sense flow, the Ultra Mag relies on two compact, high-density magnetic coils within the pipe outer wall to generate an electromagnetic field inside the pipe. As conductive liquid flows through the pipe, a voltage is created, which is measured by electrodes inserted through the flowmeter liner into the flow stream.

The voltage is converted to a flow rate reading by the Ultra Mag's signal converter, which includes a digital read-out. Electromagnetic measurement gives magmeters a wide range ability - up to 245:1 and allows for bi-directional flow readings. As the voltage generated is related only to the speed of the fluid, measurement is unaffected by changes in fluid density and viscosity.
