Frequently asked questions
Can I use a vertical drum gauge for a horizontal tank?
No, vertical drum gauges are specifically engineered to function based on gravity and float orientation within a top-mounted vertical position. Using a vertical-specific gauge like the Justrite 08531 in a horizontal tank will prevent the float mechanism from moving correctly, resulting in inaccurate readings or complete failure to register the fluid level. Always select a gauge designed for the specific mounting orientation of your tank, such as a horizontal-specific gauge for side-mounted ports.
What does the 5-inch mounting center mean on the Lenz T-550-5?
The 5-inch mounting center refers to the precise distance between the center points of the two mounting holes on the gauge. This measurement is critical for installation, as it must align perfectly with the corresponding mounting ports on your hydraulic tank. Before purchasing, verify that your tank’s mounting points match this 5-inch spacing to ensure a secure, leak-free installation without requiring modifications or adapter plates.
Are these gauges safe for all types of chemicals?
Not all gauges are compatible with all chemicals. Materials like polyethylene, galvanized steel, and polyamide have different chemical resistance profiles. For example, a gauge made for water or hydraulic fluid may react negatively if exposed to aggressive acids or solvents. You must cross-reference the chemical resistance of the gauge’s material—such as the polyethylene used in the Justrite 08531—with the specific chemical stored in your tote to prevent degradation or leakage.
Does the H-2-48 gauge require any special tools to install?
The H-2-48 features NPT male threads, which are standard for industrial pipe fittings. While specific hand tools like pipe wrenches may be required to tighten the gauge securely into the NPT port, no specialized proprietary tools are typically needed. Ensure you use proper thread sealant, such as PTFE tape, if recommended for your specific application, to ensure a tight, leak-proof seal during the installation process into your tank's threaded port.
Can I monitor temperature with these gauges?
Only specific models provide temperature data. The Lenz T-550-5 is explicitly designed as a dual-function indicator that includes a thermometer capable of displaying temperatures up to 212°F. Other models listed, such as the Vestil DGLI-4 or the H-2-48, are primarily focused on fluid level depth and do not include integrated temperature monitoring capabilities. If temperature tracking is a requirement for your chemical storage, ensure you select a gauge that lists an integrated thermometer in its specifications.
