What Hoffer Flow Controls does

Hoffer Flow Controls is a U.S. manufacturer of precision turbine flow meters headquartered in Elizabeth City, North Carolina, founded in 1969 by Ken Hoffer. The company designs and produces a comprehensive portfolio of flow measurement solutions — including the HO, HP, Lo-Co, Star, MF, API, CT, HHP, Wing Nut, Teflon, and cryogenic series — covering clean liquids, gases, and cryogenic fluids across pipe sizes from 1/4" to 72". Its core technology centers on proprietary hydrodynamic rotor positioning with low-mass rotors and deflector cones, delivering accuracies up to ±0.1% of reading, turndown ratios up to 100:1, and 5–7 millisecond dynamic response. Supporting electronics include the ICE cryogenic metering system (launched 2024), HIT series rate indicators and flow computers, and CAT series transmitters, complemented by A2LA-accredited NIST-traceable calibration services.

The company operates a quote-based, custom-configured hardware sales model with no public pricing. Distribution is handled through a worldwide network of independent sales representatives covering North America, South America, Europe, Africa, the Middle East, Asia-Pacific, Australia/Oceania, and the Caribbean, supplemented by direct quote requests and OEM partnerships. The customer base spans aerospace and defense (SpaceX, Blue Origin, U.S. Navy across multiple ship classes and submarines), oil and gas custody transfer (Sun Pipeline, Enterprise Products, Reliance Industries), cryogenic delivery fleets, municipal water, power generation, pharmaceutical/biotech, and specialty industrial applications. Certifications include ISO 9001:2015, MIL-STD-901D/167-1/461/462 plus Level 1 sub-safe, API Chapter 5.3, AGA-8, O.I.M.L. R81, NTEP, MID, and CE.

Hoffer Flow Controls is a privately held, family-owned business. Following founder Ken Hoffer's passing around 2020, ownership passed to his widow Mamie Hoffer, who serves as Owner and CEO alongside President Jason Futrell. In 2025 the U.S. Small Business Administration named Mamie Hoffer and Jason Futrell North Carolina's Small Business Persons of the Year. The company has no external investors, no disclosed funding rounds, no subsidiaries, and no M&A history, operating as a stable, self-funded specialty manufacturer.
