Eldridge Products Inc. was founded in June 1988 in Marina, California, by President and CEO Mark Eldridge. Today, with over 30 years of experience in the industry, EPI is the world’s premier manufacturer of thermal mass flow meters, switches, and metering software. With an ever-growing team of the industry’s best engineers, designers, and support specialists, EPI offers clients the reliable and accurate products they’d expect from a global leader coupled with the personal attention and dedicated service they’d expect from a world-class business.

At EPI, we understand the challenges our customers face every day when measuring thermal mass flows of all types. We also understand the opportunities that accurate measurement represents to both the bottom line and to the environment. With those challenges and opportunities always at the top of our minds, we’ve spent decades developing a full line of thermal mass-flow metering products that are unparalleled in their accuracy, ease of use, and their reliability. EPI thermal mass flow meters take the headache and complexity out of repeatable, accurate flow measurements and eliminate the need to worry about expensive system downtime.

Equally as important to us as the quality of our products is the quality of our people and the relationships we build with our customers – customers who know that, with EPI, they aren’t just buying hardware or software; they’re gaining a true partner. At the core of everything we do is the understanding that our customer’s success and our own are inextricably linked, and it’s that knowledge that drives our unwavering commitment to offering the best thermal mass flow meters and the best service the industry has to offer.
