Tank Type Float Guidewires

For float and tape tank gauge applications, the most important question by far is “what type of tank installation is required?” Varec can recommend gauge solutions based on various tank requirements, including:• Roof or ground reading• External floating roofs • Internal floating roofs (pans) • Floatwells • Stillingwells • Extreme pressures • Bolted tanks • Spheres and bullets Guidewires provide stability for the float during turbulent conditions and increased accuracy by reducing the horizontal movement of the float across the surface of the product. Accessories are available to allow in-service installations, such as weighted anchors that maintain tension in the guidewires without the need for welding inside the tank.

Product Type

Due to the float and tape measurement technique, the following are just some of the products suitable for level measurement using a float and tape device:• Crudes• Gasoline • Jet fuel • AV (aviation) gas - high octane gas for small aircraft• Diesel • Chemicals • Additives • Solvents • Water

Level Accuracy

The 2500, 2520 and 6700 offer a level accuracy of 0.2-1” (4-25 mm). The 2500 and 2520 display the measured level using a dial and counter in increments of 1/16th inch (1.58 mm) and the 6700 uses a gaugeboard with 1” (25 mm) increments.

Special Materials

Standard, moderate, severe and extreme service kits are available for applications involving extreme temperatures, pressures or aggressive products. These kits include material options for specific parts that make contact with the product in the tank, tape piping or gaugehead, such as:• Steel• Aluminum • Stainless steel • Fiber reinforced vinyl ester • Monel • Carpenter 20 steel
