Questtec Solutions

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.

Questtec gauge valves provide safe, reliable isolation for direct-reading level gauges in demanding process applications. Available in multiple styles and pressure ratings up to 4,000 psi, they feature stainless steel ball-checks for automatic shutoff in case of glass breakage and offer options for union, bolted bonnet, renewable-seat, and low-emission designs.

Questtec offers a full range of spare parts and replacement kits tailored for their liquid level gauges and valves. From industrial-standard glass (Sizes 1–9), gaskets, and shields to Steam‑Trac modules and Level‑Trac probes, these components ensure seamless maintenance and compatibility across your installed base. With widespread availability, same‑day shipping in many cases, and interchangeable kits with other manufacturer lines, Questtec delivers dependable support for uptime-critical applications.

The Questtec Glass-Trac™ series comprises rugged, direct-reading liquid level gauges designed for accurate and reliable measurement in a variety of industrial applications. Available in Reflex, Transparent, and Tubular models, these gauges accommodate pressures up to 4,000 PSIG and are constructed with durable materials such as carbon steel or stainless steel chambers and high-quality glass. Reflex models utilize prism glass to enhance liquid visibility, Transparent models allow clear viewing of liquid interfaces and color, and Tubular designs provide economical, straightforward level indication. Glass-Trac™ gauges are engineered for long service life, easy maintenance, and dependable performance in demanding process environments.

The Questtec Armored Tubular series comprises robust, direct-reading liquid level gauges designed to protect the glass tube while providing clear and accurate level indication. These gauges feature a metal frame or housing that shields the glass from impact and harsh environmental conditions, making them ideal for demanding industrial applications. Available in a variety of lengths, connection sizes, and materials—including carbon steel and stainless steel—they accommodate a wide range of pressures and temperatures. Armored Tubular gauges are engineered for durability, easy maintenance, and dependable performance where both visibility and protection are critical.

Questtec offers a range of LED illuminators designed to enhance visibility of liquid level gauges in demanding environments. Available in green, amber, or bi-color red/green configurations, these durable, low-power units provide clear distinction between liquid and vapor, mount easily to various gauge types, and deliver long service life even in hazardous locations.
