Magmeter Features Integral, All-in-One Device

March 15, 2010

The insertion style electro-magnetic flow sensor, features built-in display, empty pipe detection and bi-directional flow capabilities. The unit provides a convenient, all-in-one, integral device that allows local measurement readings, thus reducing the number of separate components required at the sensing point. The display indicates flow rate, permanent flow total and re-settable flow total in one of six user-selectable languages on an easy-to-read LCD format. An empty pipe is detected by sensing when the electrodes are not completely wetted and indicates the condition with a zero flow signal output. Frequency output is bi-directional, while the 4 to 20mA output can be set for single or bi-directional flow. All versions of the magmeter are available in a PVDF (polyvinylidene fluoride) and Hastelloy C wetted part configuration. This material combination broadens the unit’s chemical compatibility range to include a variety of highly corrosive applications. Typical applications include flow monitoring in a wide range of industries such as water and waste treatment, municipal drinking water, chemical processing, public pools and spas, aquariums, scrubbers, cooling towers, plating, beverage manufacturing and power plants. Users may select from output options including frequency, digital, or 4-20mA. Customers can connect to other Signet instrumentation via a frequency or digital (S3L) signal output. The magmeter can be quickly mounted into pipe sizes ranging from 0.5 to 8.0 inches (DN15 to DN200) using standard Signet installation fittings to ensure proper insertion depth. Other features include a dynamic flow range of 0.15 to 33 ft/s (0.05 to 10 m/s) with repeatability of ±0.5-percent of reading. Additional features include a 2-wire system design that reduces installation costs and an integral grounding ring to assure stable measurement, even in electrically noisy environments. Maximum quality is assured by complete factory testing and a test certificate is supplied with each sensor.
