The Questtec Magne-Trac™ is a magnetic level indicator designed for safe and reliable liquid level measurement in challenging industrial environments, including those with extreme pressure, temperature, vibration, and corrosive or hazardous materials. It features a non-magnetic chamber housing a magnetized float that rises and falls with the liquid level, providing a clear visual indication via an external flag-style indicator. Constructed to meet ASME B31.1 and B31.3 standards, the Magne-Trac™ offers a variety of materials and configurations to suit specific application requirements.

The Questtec Level-Trac™ system offers advanced electronic level indication and control solutions for high-pressure steam applications, utilizing conductivity and resistivity technologies to accurately distinguish between water and steam. The system comprises probe manifolds, such as the LT-500, LT-501, and LT-502, capable of operating at pressures up to 3000 PSI, and control units like the LT-210 and LT-310, which provide features including 4–20 mA outputs, programmable alarms, and fault detection. Designed to meet ASME PG60.1.1.2 standards, Level-Trac™ ensures reliable boiler drum level management and supports turbine water induction prevention systems.

The Questtec Steam-Trac™ series comprises rugged, ASME Section I-compliant direct-reading steam/water level gauges designed for high-pressure boiler applications. Models such as the ST-1000, ST-1600, and STB-3000 accommodate working steam pressures ranging from 1,000 to 3,000 PSI, featuring durable construction with materials like carbon steel chambers and tempered aluminosilicate glass. Notably, the STB-3000 utilizes a bi-color ported design with red/green LED illumination, providing clear visual differentiation between steam and water levels. These gauges are engineered for reliability and safety in demanding industrial environments.

The Questtec Guided Wave Radar (GWR) system offers precise, maintenance-free level measurement for liquids and solids in challenging industrial environments. Utilizing time domain reflectometry, it transmits high-frequency microwave pulses down a probe, measuring the time it takes for reflections to return from the process material, thereby determining the level. Designed for top-mount, direct insertion, the GWR accommodates a wide range of pressures and temperatures, making it suitable for applications requiring accurate interface and direct level measurements.
