133 ATLG

133 ATLG (Automatic Tank Level Gauge) is a high-precision float-and-tape operated tank gauging system designed for reliable level measurement in atmospheric and low-pressure storage tanks. Utilizing a large-diameter float, precision perforated stainless-steel tape, and a constant-force spring mechanism, it provides accurate and repeatable level indication with an accuracy of up to ±2 mm. The 5-digit mechanical counter display ensures clear local level indication, while its corrosion-resistant construction with SS304/SS316 wetted parts delivers long-term durability and dependable performance. Suitable for storage tanks up to 22 meters in height, the 133 ATLG supports remote monitoring through transmitters, indicators, and alarm systems, making it an ideal foundation for Tank Inventory Management Systems (TIMS). The gauge can be integrated with limit switches, smart transmitters, and other control accessories for enhanced inventory monitoring and overfill protection. Optional crank-up and liquid seal assemblies further extend its suitability for high-viscosity, solidifying, and low-pressure blanketed tank applications.
