Cryogenic Magnetic Level Gauge | Anti-frost Insulated Low-Temperature Level Indicator

The Cryogenic Magnetic Level Gauge is a specially insulated, anti-frost level measuring instrument engineered exclusively for ultra-low temperature and sub-zero industrial working conditions. Unlike standard magnetic level gauges that easily frost over, ice up or suffer floating instability in cryogenic environments, this model features a professional thermal insulation jacket and anti-condensation structure, solving the common industry pain points of blurred scale reading, frozen components and fluctuating liquid level feedback caused by extreme temperature differences.

It is specially configured for non-corrosive sub-zero media including liquid carbon dioxide, liquid propane and other cryogenic stored fluids. The entire wetted and structural components adopt high stability stainless steel and optional titanium floating parts, maintaining excellent mechanical stability and buoyancy balance under long-term ultra-low temperature shrinkage and cold shock. With a working temperature range reaching as low as -100°C, it perfectly matches the operating requirements of professional cryogenic storage and low-temperature liquefied medium tanks.

Equipped with integrated thermal insulation filling and organic glass anti-frost baffles, the gauge effectively isolates external hot air condensation, ensuring the magnetic flip indicator always stays clean and readable. It supports multiple remote signal expansion options such as cryogenic-resistant transmitters and magnetic switches, realizing on-site visual display and remote automatic monitoring for professional cold storage and cryogenic process systems.

• Professional Cryogenic Anti-frost & Insulation Design Comes with 304 stainless steel outer jacket and high-performance thermal insulation filler (polyurethane or rubber plastic cotton). The exclusive anti-frost plexiglass baffle structure effectively prevents surface condensation, frosting and icing in ultra-low temperature environments, ensuring long-term clear scale observation without manual defrosting.
• Ultra-low Temperature Structural Stability Main body adopts 304316L stainless steel with excellent low-temperature toughness. Custom optional titanium float resists cold brittleness and cold shrinkage deformation, keeping precise floating tracking and stable sensitivity under -100°C extreme cryogenic conditions.
• Optimized for Sub-zero Non-corrosive Media Purpose-built for cryogenic media that do not corrode stainless steel, including liquid carbon dioxide, liquid propane and other low-temperature liquefied gases. It eliminates measurement errors caused by low-temperature medium volatility and micro-bubble disturbance.
• Wide Cryogenic Pressure Adaptation Covers full vacuum to 16 MPa (Class 900) pressure range, adapting to pressurized cryogenic storage tanks and low-temperature sealed process vessels with variable pressure operating conditions.
• High-sensitivity Sealed Magnetic Display System Adopts high-flexibility sealed aluminum alloy magnetic flap profile. The flip structure is optimized for low-temperature viscosity and cold shrinkage, ensuring flexible flipping and accurate level response without jamming in long-term sub-zero environments.
• Low Viscosity & Low-density Medium Adaptability Stably measures cryogenic fluids with density ≥0.4 g/cm³ and medium viscosity ≤10⁻⁴ m²/s, fully matching the physical characteristics of most industrial liquefied low-temperature media.
• Flexible Custom Installation & Drainage Configuration Supports global standard flanges including GB, HG and ANSI. Equipped with standard 1/2" internal thread drain valve for regular condensate cleaning; exhaust ports and special structural modifications are customizable for special cryogenic tank designs.
• Cryogenic-grade Expandable Signal Accessories Compatible with cryogenic magnetic level switches, magnetic control transmitters and magnetostrictive level transmitters (max measuring length 3000mm). All supporting components are verified for low-temperature stability to ensure drift-free remote signal output.

This insulated cryogenic magnetic level gauge is professionally designed for ultra-low temperature and sub-zero liquefied medium storage scenarios. Its anti-frost, thermal insulation and low-temperature anti-brittle properties make it the ideal measuring device for cryogenic industrial systems that require long-term stable and maintenance-free operation:

• Liquefied Gas Storage Industry Specially suitable for liquid carbon dioxide storage tanks, liquid propane storage vessels and other liquefied petrochemical medium cryogenic storage devices, solving frosting and reading failure problems of ordinary level gauges.
• Cryogenic Chemical Process Applicable for low-temperature constant-temperature reaction tanks and sub-zero cooling process vessels, providing stable level monitoring for non-corrosive cryogenic process media.
• Industrial Cold Storage & Refrigeration System Used for large industrial refrigeration circulating tanks and low-temperature buffer containers, adapting to long-term alternating low-temperature operation environment.
• Energy & Low-temperature Fluid Engineering Widely applied in supporting level measurement of various sub-zero sealed pressure vessels, ensuring accurate liquid level tracking under low-temperature medium volatility and pressure fluctuation.

Q1: What is the difference between cryogenic type and ordinary low-temperature magnetic level gauge?

A: This cryogenic version focuses on ultra-low temperature -100°C extreme working conditions, equipped with professional thermal insulation jacket and anti-frost baffle structure. It can prevent condensation and icing in deep cold environments, while ordinary low-temperature models have no insulated jacket and cannot adapt to extreme cryogenic frosting scenarios.

Q2: Why does the cryogenic gauge need an anti-frost baffle and insulation layer?

A: Under ultra-low temperature working conditions, the huge temperature difference between the cold medium and ambient air will cause rapid condensation and frosting on the gauge surface, covering the scale and affecting observation. The customized insulation structure and organic glass anti-frost plate completely solve this problem.

Q3: Is titanium float necessary for cryogenic service?

A: Not mandatory. Standard 304/316L float works for most conventional sub-zero media. Titanium float is optional for ultra-low temperature scenarios requiring higher anti-brittle performance and long-term stability.

Q4: What is the maximum length of the optional magnetostrictive transmitter?

A: The matched cryogenic magnetostrictive transmitter supports a maximum measuring length of 3000mm, meeting most conventional cryogenic tank height requirements.

Q5: Can this gauge work under vacuum cryogenic conditions?

A: Yes. It supports -0.1MPa vacuum to 16MPa high-pressure full-range operation, adapting to various vacuum low-temperature liquefied gas storage tanks.

Q6: Does it support custom flange standards for cryogenic tanks?

A: Fully customizable. It supports GB, HG, ANSI and other global flange standards to match different cryogenic equipment installation requirements.
