The Steam-Trac STB-3000 Bi-Color Ported Gauge must be used with a red/green filter illuminator. The gauge chamber is constructed with opposing ports at an angle so that red light will pass unimpeded through the gauge in the steam phase. When water is present, refraction will allow green light, only, to pass through. The result is a clear visual indication of water level.

​Steam-Trac ST-1600 steam gauges are ruggedly built to set the industry standard for reliability in the difficult mid-pressure range from 1000 to 1600 PSI Working Steam Pressure. All materials and construction standards are within strict compliance of ASME Section 1 code requirements.

Glass-Trac Large Chamber Gauges are made in a special low-pressure series of both Reflex and Transparent Gauges. The large diameter chamber makes accurate liquid level readings possible under unusual conditions such as boiling, flashing, or foaming of the liquid. The chamber is manufactured from heavy-duty seamless steel pipe with an inside diameter of 2⅛”. Each end of the pipe is closed off with a welded plug which is drilled and tapped for ¾” NPT connections. 

Glass-Trac Reflex Gauges use prism glass to provide an excellent indication of the liquid level. All liquids appear black in high contrast to the mirror-like surface above. This clean line of separation can be sighted from many yards away. Reflex Gauges are made in three pressures series (maximum 4000 psig @ 100ºF) and are tapped for ½” or ¾” NPT connections. The standard Glass-Trac level gauges are designed for minimum -20ºF service.

The MTLS-10A is a weatherproof and explosion-proof housed magnetically-actuated electric switch designed for chamber exterior mounting on a Mange-Trac or Magne-Trac Plus magnetic level indicator having a magnetic float that rides a liquid level. 

​The QTS Maverick In-Tank transmitter is configured with a flexible hose constructed of 316L stainless steel that can be ordered in lengths from 120 inches to 866 inches with a 4-20mA. Once installed and calibrated there is no requirement for scheduled maintenance or recalibration.

The QTS Guided Wave Radar delivers an independent reading of liquid and solid levels. These top mount, direct insertion radars measure interface and direct level of liquids and solids, both of high and low pressures and temperatures. GWR technology provides dependable level indication through pulsating high-frequency microwave energy down the probe within a bypass chamber. A GWR will read the true level of the process, even in the density diverges over time.

The Magne-Trac Plus combines a Magne-Trac magnetic level indicator with a Bridle-Trac bypass chamber, in which a customer specified guided wave or non-contact radar may be installed. Although either instrument may be connected to the vessel, Questtec recommends that the bridle functions as the primary chamber. 

The Magne-Trac product line provides one of the safest and most economical ways to meet your level measurement requirements. In applications for extreme pressure, temperature, vibration, and highly corrosive or hazardous material, Magne-Trac gauge will perform where other fail. Features include lower installation costs, easy to read liquid level indication, and low maintenance.

Questtec Solutions MTLS-PNEU Pneumatic Switch deliver a consistent point switching in magnetic level applications to trigger alarms and to open and close valves with pneumatic actuators. This non-bleed, block and bleed pneumatic switch functions according to the rise or fall of the magnetic float according to the level condition.

The MTLT-5000 is based upon the magnetostrictive principle. The sensing tube contains a wire which is pulsed at fixed time intervals. The interaction of the current pulse with the magnetic field created by the magnetic float causes a torsion stress wave to be induced in the wire. This torsion propagates along the wire at a known velocity, from the position of the magnetic float and toward both ends of the wire. 

QTS offers a complete series of point level switches. MTLS-1A switches mount onto the magnetic level gauge chamber. As the magnetic level gauge float travels, it activates the switch through the chamber. Easily adjustable on the chamber, MTLS-1A switches provide low cost, dependable alarm solutions without having to make alternative modifications to the vessel.

​Questtec Solution’s Sight Flow Indicator is straightforward and dependable way to determine the flow of liquid in a process line for low pressure industrial, sterile, and hygienic applications. Horizontal installation provides direct views through a transparent sight tube for clear visibility.  Minimal wetted parts and construction elements make the Questtec Sight Flow Indicator maintenance-free.
