ABB-Magnetic level gauge KM26
Overview
The ABB KM26 is a magnetic level gauge providing high-precision, maintenance-free continuous liquid level indication for industrial tanks and vessels. Built for reliability and clarity, the KM26 gives operators a visual, accurate level display even under extreme process conditions such as high temperature, high pressure, or corrosive service – entirely without electrical power for the basic visual indication function.
Seven Star LLC supplies the ABB KM26 to oil and gas, chemical, water treatment, and power generation operators across Oman and the wider GCC as an authorized partner for genuine ABB instrumentation. Every unit is sourced through ABB’s official channel, supported by manufacturer documentation and warranty, and backed locally with configuration guidance.
Operating Principle
The KM26 uses a float containing a powerful magnet that rises and falls with the liquid level inside a chamber mounted alongside the vessel; the float’s magnetic field couples through the chamber wall to an external indicator with rotating flags or a shuttle, transmitting the liquid level to a clearly visible display without any power supply or electronic signal path required for basic visual indication.
This purely mechanical/magnetic coupling principle is what allows the KM26 to keep working reliably during a power outage or in a hazardous area where powered electronics would require additional certification – the visual indication continues regardless of instrument power availability. The float is engineered with a minimum of 75 grams of upward buoyant force and can resolve liquid-liquid interfaces down to a specific-gravity difference of just 0.03, making the KM26 useful not only for simple tank-level indication but also for oil/water and similar interface applications.
Engineering Design of the ABB KM26
The KM26 is compatible with a wide range of optional accessories, including switches and transmitters, for added functionality and remote monitoring – letting a facility start with simple visual indication and add electronic signals later as automation requirements grow, without replacing the base gauge.
The robust design ensures long-term operation with high resistance to shock, vibration, and environmental hazards, and flexible mounting configurations along with a range of materials to suit different process media provide unmatched adaptability and performance across varied installation requirements. The chamber is rated from full vacuum to 5000 psi (345 bar) and from −196°C to 538°C (−320°F to 1000°F), spanning cryogenic to high-temperature service on a single product family. Chamber materials include 304/304L, 316/316L, 317/317L, 321, 347, and 904 stainless steel, Hastelloy B or C-276, Alloy 20, titanium, Monel, and zirconium, plus thermoplastic options (PVC, CPVC, polypropylene, fiberglass) for lower-pressure corrosive service, with process connections in ½-inch to 6-inch flanged, threaded, or welded configurations rated 150 to 2500 psi. Indicator options include sealed Lexan or glass-tube shuttles for high visibility and magnetic bargraph flags in yellow/black, red/white, red/green, or red/black color combinations, with a frost-extension option for cryogenic service down to −320°F.
