Discover how to match the right float material — Buna-N for petroleum and hydraulic oils, stainless steel for high-pressure and hygienic applications, or polypropylene for chemically aggressive lower-pressure systems — to ensure long-term buoyancy, compatibility, and reliability in your Whitman Controls liquid level switch.
Introduction This is a fun one, so we’ll get right into it. In early 2025, a design/build mechanical
There are many different ways to monitor liquid levels in industrial processes, each generally designed to serve a certain band of applications within specific industries. Only a few technologies might be considered to apply universally across most types of projects, with the best example of this being hydrostatic level measurement. In practically all process, manufacturing, agricultural, and utility facilities we’ve visited, there’s always at least one hydrostatic level sensor found somewhere on the property. In our opinion, hydrostatic level sensors are so popular due to their very attractive combination of high accuracy, simple sensing technology, competitive costs, and long-term stability. If you haven’t met hydrostatic level sensors before, let’s introduce you!
Whitman Controls enters a new era as brothers William and Ramsey Brame officially take the helm from longtime president J. Yancey “Yank” Brame. As second-generation leaders, they bring deep respect for the company’s 43-year legacy and a bold vision for the future—rooted in quality, integrity, and service. Now recognized as a Service-Disabled Veteran-Owned Small Business, Whitman Controls combines time-tested reliability with a renewed focus on innovation, digital growth, and global expansion. With William’s strategic background in finance and Ramsey’s distinguished military service, the company is poised to continue delivering high-performance sensor solutions while maintaining the customer-first values that have always defined the Whitman brand.
For over 40 years, Whitman Controls has proudly served the U.S. military and defense sectors with rugged, reliable sensor solutions. Our pressure, vacuum, temperature, and liquid level switches are engineered to thrive under extreme conditions—withstanding shock, vibration, and corrosive environments—thanks to stainless steel, acid-resistant construction. Trusted across mission-critical systems, Whitman’s sensors deliver military-grade performance at a cost-effective price point, proving that strength, precision, and value can go hand-in-hand.
The COVID-19 pandemic tested the limits of global healthcare infrastructure and supply chains. Amid the chaos, innovation became essential. Nectar Product Development rose to the challenge by launching Breath Direct, a mission-driven company that developed the BDR-19, a cost-effective, high-performance ventilator designed for underserved regions.
To make this vision a reality, Breath Direct partnered with Whitman Controls, leveraging their 50+ years of sensor expertise to co-develop a custom pressure switch that met stringent medical requirements—without driving up costs. Together, they delivered a critical care solution with global impact, proving how collaboration and innovation can thrive even in crisis.
