Description
Redundant Level Measurement for Enhanced Safety
The BM26A-8000 is a state-of-the-art magnetic level indicator (MLI) specifically engineered for redundant level measurement in liquid applications. It represents the pinnacle of safety and reliability by combining a highly visible mechanical indicator with a precise electronic transmitter in a single, robust bypass chamber. This unique dual-technology approach ensures that you always have a reliable level reading, even if one of the measurement methods fails. The BM26A-8000 comes in two primary versions: the TWIN and the BI. The TWIN version features a double measuring chamber, one for the float-based flap indicator and a second for a level transmitter. The BI version, on the other hand, utilizes a unique single chamber with two separate compartments, housing both the float and the transmitter probe side-by-side.
Unwavering Reliability with Dual Technology
The core strength of the BM26A-8000 lies in its redundant design, which provides a critical layer of safety and confidence in your operations. By combining the proven reliability of a magnetic level indicator with an advanced electronic level transmitter, such as guided radar (TDR), radar (FMCW), or displacer technology, you get a system that is both accurate and fail-safe. The highly visible flaps are housed in a hermetically sealed glass tube with an IP68 rating, protecting them from environmental factors and ensuring a clear, non-powered visual reading at all times. This means that even in the event of a power outage, you can still get an accurate level reading. The rugged metallic design, made from a large choice of materials including 316L, 304L, Alloy C276, and Alloy 625, guarantees durability and a maintenance-free experience.
Exclusive Applications for the BM26A-8000
The BM26A-8000’s redundant measurement capability makes it the ideal solution for a variety of safety-critical and demanding applications. It is the perfect choice for level measurement in boiler applications within the power industry, where precise and reliable level control is paramount to prevent catastrophic failures. In the chemical and petrochemical industries, it is used in high-pressure and high-temperature reactors and storage tanks for hazardous liquids, where the combined technologies provide the necessary safety redundancy. The device is also excellent for interface measurement in oil/water separators or other processes involving two immiscible liquids, as it provides both a visual and an electronic indication of the interface level. Its high accuracy, reaching down to ±2 mm with guided radar or radar transmitters, makes it suitable for custody transfer and other high-precision applications.
Advanced Electronic Transmitter Integration
The BM26A-8000 offers unparalleled flexibility by integrating with several leading-edge electronic level transmitters. You can choose to fit it with the OPTIFLEX 7200 or OPTIFLEX 8200 guided radar (TDR), known for their excellent performance and accuracy. For non-contact measurement, the OPTIWAVE 7400 radar (FMCW) is an option, providing high-precision readings from above the media. Additionally, the BW 25 displacer level transmitter is available for applications requiring robust, mechanical-based electronic measurement. These electronic transmitters provide industry-standard 4-20 mA analogue outputs and various digital communication protocols, including HART®7, FOUNDATION™ Fieldbus, and Profibus-PA. This allows for seamless integration into your plant’s control system, enabling advanced monitoring and control functionalities.
