Self-Cleaning Wastewater Flow Meter Designed For Effluent Applications

Self-Cleaning Wastewater Flow Meter Designed For Effluent Applications

Instrument engineers at municipal water facilities and industrial process plants with wastewater treatment operations will find the Ultra Mag® Wastewater Flow Meter from McCrometer provides superior measurement accuracy in effluent applications. It operates in treated water or even sludge or slurries, requires minimal maintenance and offers a long-life of trouble-free service at a low life-cycle cost.

With its non-invasive, no-moving parts flow sensing technology, the Ultra Mag inline flow meter delivers exceptional flow measurement accuracy of +0.5 percent in water effluent with repeatability of +0.05 percent. The Ultra Mag measures liquid flow in 2 to 36 inch lines from 0.2 to 49 fps at pressures of up to 300 psi, depending on the selected flange configuration. It operates in high temperatures up to 170°F too.

Manufactured with 316 Stainless Steel, the Ultra Mag’s electrodes feature a unique bullet-shaped design that is self-cleaning for long service and virtually no maintenance. Combined with its rugged NSF-approved epoxy liner that also provides outstanding electrical insulating properties, the Ultra Mag Flow Meter sets a new standard for ease-of-use and value. 

The advanced Ultra Mag’s unique UltraLiner™ technology gives users an exceptionally accurate, reliable and durable instrument. Municipal process and industrial plant engineers who have in the past had to trade-off accuracy in harsh environments against low maintenance and long-life, will find the Ultra Mag to be the ideal solution -- especially in wastewater effluent, as well as in sludge and slurries.

Debris and solids will not clog the line or cause excessive wear to the Ultra Mag, thanks to its non-intrusive sensing element that nearly eliminates maintenance requirements. Combined with the superior abrasion and corrosion resistance of McCrometer’s fusion-bonded epoxy UltraLiner, this magmeter is a superior choice for installation in hard-to-reach areas and applications where maintenance is awkward or especially time-consuming.

To sense flow, the Ultra Mag relies on two compact, high-density magnetic coils placed 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 then converted to a flow rate reading by the Ultra Mag’s signal converter, which includes a digital read-out.

The highest possible flow measurement accuracy is provided by the Ultra Mag’s highly intelligent micro-processor-based signal converter. Advanced electronic components within the signal converter produce an exceptionally high signal-to-noise ratio for high measurement accuracy even in slurries or sludge under variable flow conditions.

Magmeters provide worry-free flow measurement in situations where reliability and low maintenance are critical. Unlike mechanical flowmeters, there are no moving parts to clog or break -- making them low maintenance devices. Electromagnetic measurement gives magmeters a wide rangeability -- 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 -- making for a very stable and reliable flowmeter.
