High Precision Magnetic Level Gauge for Industrial Liquid Monitoring Needs¹

Product DescriptionProduct DescriptionWorking PrincipleBNA Bypass Magnetic Level Gauge:Employs the communicating vessels principle to transfer liquid into the chamber. A permanent-magnetic float moves inside the chamber.UNT Top-Mounted Magnetic Level Gauge:Connects to the tank top via process interface. A stem with top-mounted magnetic element links to the float inside the vessel.Construction & Safety Features:The chamber and float housing are manufactured from austenitic materials, enabling unimpeded magnetic transmission that precisely tracks the liquid surface. This sealed chamber-vessel system forms a pressure-resistant and leak-free safety structure.Level Indication Principle:Externally attached magnetic flags react to magnetic coupling. As liquid level changes, the magnetic float's vertical movement inside the chamber drives corresponding real-time flag rotation. This achieves contactless level detection.Visual Level Indication:Externally mounted bicolor magnetic flags (half-white/half-colored) rotate 180° via magnetic coupling. Rising liquid turns flags from white to red/blue; falling levels revert flags to white. This provides continuous, power-free level indication - the current liquid level is always indicated by colored flags.Technical AdvantagesSimple, robust, compact design Pressure-isolated construction between bypass tube and indicator section Measures/indicates level of corrosive, flammable, toxic, high-temperature, agitated, and contaminated liquids Magnetic flag indication – no external power required Universal industrial applicability with corrosion-resistant materials Pressure rating: Full vacuum to 420 bar Temperature range: –160°C to +450°C Custom-engineered solutions for extreme pressure/temperature conditionFeaturesWide measurement range, intuitive and clear reading Mechanical structure, safe and reliable Few sealing joints, not easy to leak The indicating part is completely isolated from the measured mediumInstallation DiagramBypass-TypeTop-MountedSpecificationNo. Type of Level GaugeScope of Application and Purpose1General TypeThe HCHZ float level gauge is a local display instrument, which is widely used in petroleum, chemical, electric power, light industry, environmental protection and other departments to continuously display the liquid level in open or pressure vessels.2Underground Tank TypeSuitable for various underground fuel oil or chemical storage tanks, and the liquid level can be displayed on the ground. Not suitable for working occasions with strong vibration and strong magnetism. (Working pressure ≤1.6MPa; Measurement range ≤2m)3Electric Remote Transmission TypeIt is a magnetic float level gauge with 4~20mA electric remote transmission and upper and lower limit switch liquid level transmitter.4Explosion-proof TypeIt is an explosion-proof magnetic float level gauge with 4~20mA electric remote transmission and upper and lower limit switch liquid level transmitter.5High-temperature TypeSuitable for media with a temperature of 0℃~200℃. When the working temperature is higher than 200℃~400℃, a heat dissipation device can be provided. Especially suitable for liquid level display of containers with a pressure of 4.0MPa~6.3MPa. It can also output 4~20mA electric remote transmission signals and upper and lower limit switch signals.6Jacketed TypeSuitable for instruments where the measured medium has high viscosity and requires the use of heat tracing devices when the temperature is relatively high or low.7Anti-corrosion TypeEspecially suitable for liquid level measurement and indication with corrosiveness and toxicity. (Working pressure ≤1.6MPa; Measurement range ≤2m)Note: For containers containing solid suspended impurities and ferromagnetic impurities, our factory can provide dust accumulation devices.Technical ParametersNormal Working ConditionsAmbient Temperature-25℃~70℃Relative Humidity5%~100% including condensation and direct wetnessAtmospheric Pressure86kPa~108kPaMeasurement Range500mm~3000mm in stepsMeasurement AccuracyTracking indicator ±20mmFlap indicator ±25mmWorking Pressure1MPa, 1.6MPa, 2.5MPa, 4MPa, 6.3MPaMedium Density0.5g/cm3~1.5g/cm3 in stepsMedium Viscosity≤0.05Pa·sMedium Temperature-25℃~80℃Tracking Speed≤0.5m/sMaterial in Contact with Medium1Cr18Ni9TiControl Point Error±10mmHysteresisNot exceeding the basic errorRepeatability ErrorNot exceeding the basic errorContact Container of Switch Control PointAC or DC220V·1A (pure resistive load)Minimum Distance between Control Points (mm)50Shell Protection ClassIP54Explosion-proof ClassdⅡBT4Electric Remote Transmission AccuracyMeasurement Range (m)0~0.50.5~22~3Measurement Accuracy (mm)±2±1.5, ±2±1, ±1.5, ±2Note: If users use other standard flanges, they can propose it specifically, and our factory will supply according to the requirements. The measurement range of the instrument is the center distance of the flange connection, and the center of the lower flange is the zero point indicated by the instrument. The user's flange should ensure that the position of the screw holes is centered and the flatness, perpendicularity and center distance of the upper and lower flange end faces. Otherwise, it will affect the normal installation and use of the instrument. The float chamber should be kept clean and free of impurities, especially ferromagnetic impurities. When the medium is not clean, adsorption and filtration devices should be added to ensure the normal operation of the instrument. There is a sewage discharge space at the lower end of the instrument, and there is a G1/2" threaded interface at the lower end of the valve for connecting the connecting pipe.Order InformationHC-UHZManufacturer's NumberPGeneral TypeTHigh-temperature TypeBasic TypeDTop-mounted TypeYHigh-pressure TypeFAnti-corrosion TypeHHigh-temperature and High-pressure TypeRHeat-tracing TypeBExplosion-proof Type (Bd is flameproof type, Bi is intrinsically safe type)0Atmospheric Pressure44.0Process Pressure (MPa)11.056.321.661032.58Other10.45-0.5140.75-0.9Medium Density (g/cm3)20.51-0.6550.9-1.030.65-0.7561.0-1.803042UPVC (including PVC)Main Material1316/316L3Lined with F4 (or PE)4Other0Flip-column On-site Display TypeDisplay Mode1Transmission Output Type2Flip-column with Transmission Output Type3Other Types0No Alarm PointAlarm Code1One Alarm Point2Two Alarm Points3OtherXOther Contents Such as: Range (L)Other OptionsExample: HC-UHZT14020L800 has a medium density range of 0.75~0.9g/cm3, temperature: 200 degrees, working pressure 1MPa, and measurement range 800.CertificationsIn terms of certifications, the company holds SIL certification, which indicates that the products meet relevant standard requirements in terms of safety integrity level and are suitable for industrial scenarios with high safety requirements; the explosion-proof certificate proves that the products have the ability to operate safely in explosive hazardous environments and can be widely used in industries with potential explosion risks such as petroleum and chemical industries; the computer software copyright registration certificate (mentioned earlier) reflects the company's achievements in the field of software research and development and helps the products achieve more intelligent data analysis and control functions.After Sales ServiceStandard Warranty: 12 months or 2,000 operating hours (whichever comes first).Global Support: 24/7 technical assistance and spare parts supply.Training: On-site or remote operation/maintenance training.Company ProfileAnhui Hechuang Intelligent Manufacturing Co., Ltd.Anhui Hechuang Intelligent Manufacturing Co., Ltd. is located in Hefei, a picturesque industrial city renowned as the "City of Lakes and Innovation."
