Description
A Master of Cryogenic and Low Temperatures
The BM26A-6000 is a highly specialized magnetic level indicator (MLI) engineered for the most demanding applications involving liquefied gases and cryogenic media. This device stands out due to its ability to perform continuous level measurement in process or storage tanks at extremely low temperatures, reaching down to -196°C (-320.8°F). Its rugged metallic design, combined with various thermal insulation options, ensures both safety and reliability. The principle of operation is simple yet effective: as the liquid level changes in the tank, a bypass chamber attached to the side fills or empties, causing a float inside to rise or fall. This movement is magnetically transmitted to a highly visible, external flap display, providing a clear and precise reading without any need for a power supply.
Unwavering Reliability in Extreme Conditions
The core strength of the BM26A-6000 is its exceptional performance in extreme cold. The device is specifically designed to provide stable and accurate level measurement even in the presence of evaporating or boiling liquids, a common challenge in cryogenic applications. This is crucial for maintaining safety and preventing tank overfills or run-outs. The device’s robust metallic construction ensures it can withstand high process pressures up to 40 barg (580 psig) and a wide temperature range from -196°C to +200°C (-320.8°F to +392°F). The flaps that display the liquid level are housed in a hermetically sealed glass tube with an IP68 ingress protection rating, protecting them from condensation and other environmental factors. The use of a titanium float is a key feature, allowing for precise measurement of low-density cryogenic media.
Exclusive Applications for the BM26A-6000
The unique capabilities of the BM26A-6000 make it indispensable for several critical applications. It is the perfect choice for level measurement in tanks storing liquefied natural gas (LNG), liquefied petroleum gas (LPG), and other cryogenic fluids like liquid nitrogen, oxygen, and argon. In the petrochemical industry, it provides safe and reliable monitoring of liquefied ammonia (NH3), liquefied carbon dioxide (CO2), and liquefied propane in storage and process tanks. The device’s compliance with safety standards such as ASME B31.3 and ASME B31.1 ensures its suitability for high-pressure piping systems. Its non-powered visual display is a critical safety feature for remote installations or during power failures, providing a continuous, reliable level reading in any circumstance.
Optional Features for Modern Systems
While the visual indication of the BM26A-6000 is a key safety feature, the device can be configured with a variety of optional features to meet the demands of modern process automation. For automated alarming and control, it can be equipped with optional reed switches (3-wire, NAMUR) to signal high or low-level conditions. For continuous electronic monitoring, a reed-chain level transmitter can be added, providing an industry-standard 4-20 mA output. This allows for seamless integration with a plant’s Distributed Control System (DCS) or PLC. The transmitter also supports advanced digital outputs such as HART®7, FOUNDATION™ Fieldbus, and Profibus-PA, giving you the flexibility to connect to digital networks. These options transform the BM26A-6000 from a simple visual indicator into a comprehensive level measurement solution.
