The Ultra Mag wastewater flow meter from McCrometer provides a high level of measurement accuracy in effluent applications for industrial process plants with wastewater treatment operations. According to the company, this flow meter 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 also operates in high temperatures up to 170°F.
Manufactured with 316 stainless steel, the Ultra Mags electrodes feature a bullet-shaped design that is self-cleaning for long service and low maintenance. The company's UltraLiner technology gives users an exceptionally accurate, reliable and durable instrument.
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, according to the company. Combined with the superior abrasion and corrosion resistance of McCrometers fusion-bonded epoxy UltraLiner, this magmeter is a good 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 Mags signal converter, which includes a digital read-out.
The highest possible flow measurement accuracy is provided by the Ultra Mags highly intelligent microprocessor-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.
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, thus ensuring stability and reliability.
