5. Product OfferingMagnetic Level GageReplacement of sight glass8 basic styles with customized optionsSold as an engineered productBest lead times in industryLow maintenance option for end usersHighly visible (200 ft)Customizable options
6. Product OfferingMLI + Magneostrictive TransmitterSend a signal back to the control room indicating level (Continuous)Current pulse from transmitter start pulseInteraction of pulse and magnetic field causes a torsional wave return pulseTime between start pulse and return pulse is proportional to position of float
7. Product OfferingMLI + Guided Wave RadarContinuous level measurement back to control roomUsed as separate instrument from MLIHigher temp/pressure capabilitiesDual Chamber designGUIDED WAVE RADAR is based upon the principle of TDR (Time Domain Reflectometry). Pulses of electromagnetic energy are transmitted down a probe. The pulse is reflected when it reaches a liquid surface.
8. Product OfferingLevel SwitchesQuest-Tec level switches are hermetically sealed, non-mercury, bi-stable latching switches designed for use with Magne-Trac level gages. The bias magnet design latches the switch maintaining the contact after the level continues to rise or fall. The switch will change state when the float magnet passes by. The switches are fully adjustable and non-invasive. Level switches are mounted to the Magne-Trac chamber with all 316 Stainless Steel worm gear pipe clamps. Switch points can be changed easily at any time without any interruption to the visual indication or process.Available in 1, 5 & 10 AMP

10. 4 Key Factors in Quoting!!Specific gravity / Process fluidMaximum/Operating PressureMaximum/Operating TemperatureCenter to Center Dimension
11. Specific Gravity/Process fluidWhy both?Essential pieces of information that feed into the overall design of the gage.Will directly affect the float design, chamber size and dimensions of “dead” zone.Specific gravity vs. chamber design
12. Pressure / Temperature ConsiderationsHaving a direct affect on the specific gravity of a process fluid, knowing the operating pressure and temperature is essential to overall design.Pressure can change sizing of the chamber during specificationTemperature can be limiting on the type of technology available and needs to be taken into consideration in all applications (cold or hot)Flag material will change in high temp scenarioLook for process media that solidifies at certain temperature and offer heat tracing options or freeze protection
13. Float Design (Oblong)Oblong available in 316, titanium, CPVC, hastelloy C and carbon fiber316 SST floats are .020” wall thickness and used in applications up to 400 PSISG range is .60 and up360 DEG ring magnetMost common used floatCan easily be replaced (within a few hours)
14. Float Design (Spherical) Titanium materialDesigned to handle up to 2800 PSIWill directly affect sizing of the chamberMay be necessary under .60 depending on pressure/temperatureWill affect the overall length of the gage (be mindful of sizing limitations)
15. Chamber DesignStandard chamber is 2” SCH 40Available options: 2” SCH 40, 2.5” SCH 80, 3” SCH 40 & 3” SCH 80QTS does not do any SCH 10 (is this a limiting factor?)Material options: 304 SST, 316SST, Hastelloy C, CPVC, Monel and PVDF (Kynar)Material combinations?Full bore process connections available (no pulled extrusions)Vent / Drain connection types

18. Branch Connection Reinforcement
19. Vent / DrainAll MLI’s require a flanged end to install the float.Drain Plugs: ½”, ¾” or 1” NPT / SW 316 SS (or like material)Vent Plugs – ½”, ¾” or 1” NPT 316 SS

28. Field ConsiderationsDirty serviceHow does dirty service affect a magnetic gage and its field useHow do we combat the issues associated with dirty service?
29. Field ConsiderationsFlashingOversized chamber principle much like what's offered in dirty serviceGuide rodsInsulation?
30. Field ConsiderationsInterface applicationsThere are many applications where the interface between two immiscible liquids must be monitored or controlled. These involve oil and water separators, wastewater disposal tanks and a multitude of chemical processesMags can be used with a specially weighted float that will sink in the top layer and float in the bottom layer provided there is a specific gravity difference of 0.1 between liquids
31. Field ConsiderationsBoiler Drum levelIf the plant is adhering to PG60 special consideration needs to be taken in magnetic gage specificationA magnetic gage can only be used up to 900 PSIA magnetic gage falls under “remote level indication” not direct reading sight glassGreat chance to use multiple “remote level indicators” off one set of taps
32. Kynar Level GagesFrequently a level gage application requires the wetted parts to be hastelloy, zirconium, titanium or other exotic material because of a highly corrosive nature. As a cost savings we can offer gages made from solid Kynar. The material is similar to Teflon but is less porous. It is limited by a temperature of 280 DEG F. It is only about 25-30% more than stainless but about half the price of a hastelloy gage
33. Gages in the Food IndustryQTS has a gage that can be “3A” approved for use in the dairy industry. Anyone in the food industry generally recognizes this approval and the “3A” symbol. Whether it is brine, vinegar, beer, vegetable oil or mile products they want to have a sanitary version of the MLI.
34. Pump up / Pump downVarious types of process tanks frequently need some type of automatic level control. Receiver vessels need to be pumped to storage when they become full (pump down) and feed tanks need to be refilled when they become low (pump up)The QTS 3 or 5 AMP reed switch can be used in conjunction with a latching relay controller for pump up and pump down operation
