Standard Side-Mount Magnetic Level Gauges - Made in the USA - Two Week Lead Time

KOBOLD's NBK Magnetic Level Gauges are made in the USA, feature a two week lead time, and provide reliable visual indication, continuous measurement, and/or control of liquid levels. They are built for free-flowing compatible media types with viscosities less than 200 cPs. The NBKs feature an all metal construction that eliminates the breakage and leakage problems frequently experienced with other glass tube designs.

The NBK's design relies on the hydrostatic pressure principle to display the tank's liquid level in a side-mounted high visibility measuring gauge. A float, which contains a ring magnet, rises and falls with the liquid level in the bypass tube. Visual indication, signal transmission or switching may be achieved by mounting these magnetically-sensitive devices on the exterior of the bypass tube. These devices then track or are activated by the ring magnet located inside the float as it moves with changes in liquid level.

Compact Magnetic Level Gauges

For shorter tanks or applications with a lower pressure requirement, consider the compact NBK-M Economical Level Indicator. It provides the same rugged and reliable measurement as the standard NBK for a fraction of the cost and is still made in the USA.

Tank-Top Mounted Magnetic Level Gauges

For application installations that require the level indication gauge to be mounted from the top of the tank, KOBOLD also offers the NBK-04 Tank-Top Mounted Magnetic Level Gauge.

Application Guide Required for Product Specification

Every NBK order includes free application verification by a KOBOLD engineer. MLI part numbers are easy to get wrong — configuration options interact, and combinations that look valid on paper sometimes can’t be built or won’t perform in your process. Before we fabricate anything, our engineers confirm that the part number you’ve spec’d is the right one for your exact application, so your gauge is right the first time. Have your details ready? Download the Application Guide from the Resources tab above and send it to customerservice@koboldusa.com — or skip the paperwork and schedule a free engineering consultation, and we’ll capture everything in one call. Either way, you’ll have a verified quote fast and a finished gauge typically in two weeks or less.

Important Notice

Unless this is a repeat order of a previously specified product with Kobold, we cannot accept orders or provide quotations without a completed Application Guide. Product numbers selected without proper application review may not meet your system requirements and could result in performance issues or compatibility problems.

Even if you believe you've identified the correct part number, the Application Guide process is required to verify compatibility and ensure a streamlined quote/order process.
