Magetic Level Gauges Used throughout the world withi a vast rage of idustries the TC Fluid Cotrol rage of Magetic Level Gauges is particularly suited to applicatios where hazardous liquids or gases are i use. All of these istrumets are made to order ad our egieers will provide expert guidace o the desig ad maufacture of Magetic Level Gauges for specific applicatios. 1 www.tc-fluidcotrol.com
Magetic Level Gauges The well prove TC Fluid Cotrol Magetic Level Gauge is particularly suitable for duties where dagerous ad toxic liquids or gases are ivolved ad where the followig features, beefits ad optios are required:- Immediate ad accurate respose to level chages, givig clear ad sharp legibility. Cotiuous idicatio of liquid level. Local ad remote display. Poit switchig facilities. Robust, shockproof ad completely sealed for safety. No leakage to atmosphere. Particularly suitable for dagerous or toxic fluids. Ideal for liquid iterface applicatios. Powerful omi-directio maget system guide-free float. Display ca be rotated through 360 o irrespective of float positio. Desig Cosideratios Magetic Level Gauges, deped ot oly o the itegrity of the chamber but also o the float desig ad the ability to satisfy all desig parameters, ie. specific gravity, pressure ad temperature, without compromisig the magetic likage to the display ad associated cotrols. May competitive systems sacrifice display performace by usig smaller ad weaker maget systems to achieve low SG ad higher pressures, ivariably with detrimetal effect. Others use guided ad veted floats to achieve the same result, which agai ca prove limitig ad troublesome. The Advatages Of The System The system, built o may years experiece, has take all these factors ito cosideratio ad desiged out these problem areas. This uique system uses a pateted ferrite moulded wafer system, which combied with a sealed guidefree float carryig a powerful omi-directioal maget system, provides ultimate performace ad reliability, eve uder the most severe coditios. Automatic float warig. High pressure capability up to 400 bar uveted. High temperature capability stadard up to 450 o C. Stadard SG rage 0.3 2.2 Ulimited legth (6m i cotiuous legth). Top mouted optios. PTFE/PFA lied, PP, PVDF ad upvc versios. Simple to egieer ad easy to istall. Elimiates prevetive maiteace. A ecoomical alterative to:- Covetioal level gauges ad other level measurig systems. Display uit protectio up to IP66/67 Operatio The TC Fluid Cotrol Magetic gauge is desiged so that the liquid beig measured is eclosed withi a sealed chamber. A stailess steel, titaium or plastic float fitted with a permaet omi-directioal maget moves freely iside the chamber ad actuates the magetic wafers withi the idicator. As the float rises or falls with the liquid level each wafer rotates 180 O ad so presets a cotrastig colour. Those wafers above the float show white, whilst those level ad below show red the idicator the presets a clearly defied ad accurate level of the liquid i the chamber. The wafers resist accidetal disturbace (e.g. vibratio) due to their edge magetisatio ad mutual attractio. To complemet the rage, the Magetic Gauge ca be supplied with Alarm Switches or Trasmitter ad Cotroller to remotely display the liquid level. www.tc-fluidcotrol.com 2

Coloured Wafers 25mm wide, red ad white (or gree, red, black ad yellow) remai magetically locked i the vertical positio util disturbed by the greater magetic force of the float maget. Automatic Float Warig The wafers at the bottom of the idicator are mouted with their colours reversed. Should the float reach that level, they agai preset a sharp, immediately readable idicatio of float failure. Sealed Float of reiforced stailess steel, titaium or corrosio resistat plastic. Sealed Chamber Sealed chamber fabricated from stailess steel pipe, corrosio resistat plastics or other exotic o magetic metals. Iterface The gauge is ideally suited for measurig liquid iterfaces. Floats are available to meet a variety of specific gravities to suit the liquids beig moitored. Poit Switches ca be fitted o the gauge at ay level to provide sigals at high, low ad itermediate poits. Trasmissio ad Moitorig for Remote Display Ca be offered as a complete origial equipmet package or retro-fitted to a existig Magetic Gauge.
