Our tank gauges and all of the components used on our tank gauges are produced by us or by other American Manufacturers. All of our gauges are manufactured in the USA, complying with the Buy American Act.
We are a small family owned business in Green Bay, WI. Krueger employs 15 full and part time employees. We have been in business for over 65 years and have manufactured over 3 million level gauges. Several years ago Krueger expanded the business to include a machine shop. The machine shop started as a source for us to produce some of our own parts for our gauges, and has expanded into a cornerstone of the business.

Krueger Sentry Gauge will deliver as fast as our customers require whenever possible. And there are no minumum orders.
Mission Statement: Provide a quality product for our customers, and maintain a relaxed and flexible work environment for family oriented employees. We are not a bottom line profit oriented company. Compassion for our customers and our employees is the driving force behind this company.
