Level gauges are the simplest, most 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. Level gauges are installed so that the liquid level in the transparent sight tube is always the same as the liquid level inside the tank or vessel. Level gauges can be used at operating pressures up to 285 psi. For higher operating pressures, use level gauges
SIMPLE, RELIABLE, AND MAINTENANCE-FREE
Level gauges are simple: the only components (not including mounting hardware) are the armored shield, the sight tubing, and two self-sealing Super-Seal inserts. These products are maintenance-free, because only the Teflon Super-Seal inserts and the borosilicate sight tubing are exposed to process fluids. Once the gauges are installed, they do not have to be removed and disassembled for inspection or cleaning. Standard shields are epoxy-coated carbon steel.
SUPERSEAL INSERTS FOR PERMANENT, STRESS-FREE SEALING
Level gauges incorporate patented PTFE Teflon Super-Seal inserts, which seal on the outside diameter, not the ends, of the sight tube. Since Super-Seal inserts allow sight tube movement without leaking, stresses caused by differential expansion between the sight tube and the housing are eliminated. There are no elastomer seals or o-rings to inspect and replace: Super-Seal inserts last the life of the sight tubing.
LEVEL GAUGE QUALITY PROGRAM
Level gauges are quality ensured to exceed performance requirements with maintenance-free service. Systematic reviews of vendors, materials, processes, and product construction are consistently evaluated by management for improvement through technical innovation.
