M-SeriesUSTD IIProduct level, Interface level, temperature and volume shall be measuredcontinuously, highly accurate and administrated. The best to do with LEVELPLUS-<strong>USTDII</strong>, the precise, robust and pioneering tank gauge of <strong>MTS</strong> for gasstations.At the same time it can measure the level of product and interface via two floatsand, in addition, determine with 5 integrated digital thermometers the individualand avarage temperature of the thermometers submerged in the liquid. Thisserves in connection with a control unit to achieve exact calculations of value ormass in filling stations. For remote data transfer to the tank managementsystem, the well-known digital RS 485-Interface is used.- Easy to install- No handling with fuel dip stick- Measures product- and water level- Continuous temperature control via 5 DT- Absolute high-precision measurements- No recalibration- Replacement without tank openingsafetybarriers... only 3safety barriersper gas stationRX/TX (+)RX/TX (-)powersupplyEarth ground... up to 8 <strong>Sensor</strong>s*per Network*extension up to 32 gaugessafetybarriersSystem Expansion CapabilitiesTank Controll System/Interface Convertere.g. REPSI-BusHazardous AreaTank No.1Tank No.2 Tank No.3... ...Tank No.8Gas Station System Architecture<strong>MTS</strong> <strong>Sensor</strong>sI 2 I


M-SeriesUSTD IILEVEL PLUS gauges are based on the magnetostrictive measuring technology,which is successfully used for more than 28 years at <strong>MTS</strong>.Magnetostriction is a combination of magnetic (non contact) and ultrasoniceffects (speed control).According to <strong>MTS</strong> know-how, two magnetic fields interact, and a torsionalstrain pulse on the sensor element results. The running time of the the pulse isused to determine the level measurement with a high degree of accuracy andreliability.All LEVEL PLUS Tank Gauge systems base on this principle, which ensures areally innovative and promissing measuring system for continous level measurement.WaveguideOuter PipeFloat(moves as level changes)Position magnetMaterials / Mechanics<strong>Sensor</strong>head Stainless steel 1.4301Sealing IP 67; NEMA 6<strong>Sensor</strong> outer pipe Stainless steel 1.4404MountingNPT fitting, flangeFloat styles Gas station: Stainless steel 1.4571Connection5-Pin connector, female M12 with5 m pigtail, extra chargePressure ratingUp to 4 bar on stainless steel floatOption: higher pressure floats on requestSafety approvalEC-Type-Examination CertificateII 1/2G bzw.

M-SeriesUSTD II<strong>Sensor</strong> DesignAll LEVEL PLUS gauges, based on the non-contacting magnetostrictive technology,only have one moving part - the float. this simple design ensure no sheduledmaintanance or recalibration will be required - ever.The absolute measured level reading is also after a breakdown immediately thereafteravailable. The gauge is composed of three parts: The sensor rod with theintegral sensing element for levels up to 3,8 mm and 5 DT for temperaturemeasurements. The sensor head, a stainless steel housing with the sensor electronicand the float with a built-in magnet on the gauge pipe. Choosing the suitablesecond float, an additional measurement of the interface level is possible.Ordering GuideRemove HousingUse a 2 mm inbus-key and turn the 2screws clockwise into the housing-sokket.Remove the housing carefully.Mounting of housingPush the housing carefully over the flangewith O-Ring. Position the holes in linewith the screws. Turn the screws anticlockwiseuntil they are in line with theouter surface of the housing.LEVEL PLUS-USTD IIUnit of measureM - Millimeter (xxxx mm)U - Inch (oxxx”)Gauge order lengthFrom 740 to 3800 mm(49 in. to 149 in.)Mounting6 - 3/4” / NPT adjustable fitting.others e.g. 1”/1,5”/2” NPT or corresponding metric fitting (add. price)8 - DIN- or ANSI-flange resp. welded fitting (add. price)H - Fill tube mounting (hänger w. centering disk) Category 2-apparatus7 - 5 m pigtail (blue), PG-fitting with strain-relief9 - 5-pin plug, male contacts M12Floats1.
