Level Switch – AXXX

Flowline Inc.

Rugged polypropylene multi-point level switch package for corrosive liquids
Offered in 3 sensing technologies for broad application coverage: ultrasonic, vibration & buoyancy
Adjustable level switch points enable sensor adjustment in the field
Select from 1 to 4 switch points and the custom switch points
Each switch connects directly to a PLC/SCADA

The Smart Trak AXXX with Compact Junction Box is a multi-point liquid level switch package designed for reliable detection up to 10 feet (3 meters) with 1-4 adjustable level switch points. It features a compact junction box for integral wiring termination and is available in three sensor technologies: ultrasonic, vibration, and buoyancy. The package is made of rugged polypropylene, suitable for corrosive liquids, and includes a NEMA 4X rated junction box or controller enclosure. It is ideal for applications such as process, sump, and day tank level monitoring, offering high level alarm and/or low level alarm capabilities. The product is compatible with PLC/SCADA systems and can be mounted on the top wall of a tank. It is available in both intrinsically safe and general purpose classifications, with a CE IP65 rating. The product supports field adjustment of switch points and offers a range of specifications including accuracy, repeatability, and process temperature ranges.

Flowline Inc. Flowline, Inc., based in Los Alamitos, California with over 25 years of specialization in level measurement and sensing products, designs, manufactures and markets liquid and solids level measurement and control instruments for chemical, water, wastewater, oil, and dry solid applications across industrial manufacturers, chemical distributors, municipalities, and energy or food providers. The company's advanced sensing technologies include 80-GHz radar, reflective ultrasonic, guided wave, and pulse radar sensors that measure tank inventories, automate tank processes, ensure workplace safety, and protect the environment across diverse liquid and solid asset management applications. Flowline's product portfolio includes dedicated hydrogen peroxide level sensors, transmitters, and switches offering reliable continuous or point-level measurement of hydrogen peroxide in tank, storage, or day-tank applications—relevant to water treatment and disinfection processes that use hydrogen peroxide as an oxidizing chemical rather than molecular hydrogen fuel applications. The company's non-contact, corrosion-resistant radar sensor technology (as demonstrated in a case study for a Canadian meat processor monitoring hydrogen peroxide and peracetic acid disinfectant levels) offers reliable performance unaffected by foam, turbulence, and precipitation in demanding industrial chemical processing environments.
