With its rugged NSF-approved epoxy liner that also provides outstanding electrical insulating properties, the Ultra Mag® flow meter from McCrometer combines superior flow measurement accuracy in liquids, slurries and sludge with low maintenance and long-life to set a new standard for performance, ease-of-use and value.

The advanced Ultra Mag is a leading-edge electromagnetic flow meter, which is field-proven to meet the specific needs of users in the water and process control industries. It employs a unique UltraLiner™ technology to give users an exceptionally accurate, reliable and durable instrument. Process and 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 slurries and sludge.

The Ultra Mag measures flow with a non-intrusive sensing element, which means debris and solids will not clog the line or cause excessive wear. 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 requiring minimal maintenance in tough environments.

The precision Ultra Mag is accurate to +0.5% of flow rate, with a repeatability of +0.05%, over a wide flow range from 0.2 to 49 FPS. It is designed for line sizes from 2 to 48 inches, and it is compatible with temperatures from 14 to 170F (-10 to +77C) at pressures up to 300 psi. Its non-intrusive flow sensing element also eliminates head loss.

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 flow meter 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 flow meters, 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 flow meter.
