Armored Tubular Liquid Level Indicator

Questtec Direct-Reading Level Gauges are a simple and reliable way to determine the level of liquid in a tank or vessel, because they give you a direct view without compromising the integrity of your process system.

Questtec level gauges operate such that the liquid level in the transparent sight tube is always the same as the liquid level inside the tank or vessel. Questtec Armored Tubular level gauges can be used at operating pressures up to 285 psig. For higher operating pressures, use Questtec’s Magne-Trac Magnetic Level Indicator, Steam-Trac, or Glass-Trac Gauges.
