LibertyCES has documented Clamp-On Ultrasonic Flow Meter in Hydrocarbons/Fuels/Oils service, including gasoline, diesel fuel and kerosene. Wetted materials to confirm: Non-wetted, PFA Teflon and Excluded by physics. Documented models include GF Signet U1000 fixed clamp-on and GF Signet U3000-U4000 fixed clamp-on. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Materials documented for this service
- Non-wetted (clamp-on) — no material compatibility question at all
- PFA Teflon (UltraFlo 1000 in-line)
- Excluded by physics: magmeters require minimum conductivity 20 µS/cm (GF Signet 2551 and 2552), which hydrocarbons do not meet
- GF Signet 2000 in-line micro flow rotor explicitly 'not recommended for strong oxidizers'

GF Signet's own insertion magmeters (2551, 2552) both require a minimum liquid conductivity of 20 µS/cm to function at all — hydrocarbons don't meet that threshold, so a magmeter physically cannot meter gasoline, diesel, or oil regardless of body-material compatibility. That's a hard technology exclusion, not a material-selection question.
Most suppliers would spec a magmeter or turbine meter for fuel oil the same way they would for water, because the body material looks compatible on paper. It isn't a material problem at all — hydrocarbons fall below the 20 µS/cm conductivity floor magnetic flow sensing requires, a physics exclusion no wetted-material upgrade fixes. Liberty CES specifies clamp-on ultrasonic (zero wetted parts, so compatibility is moot) or a PFA-lined in-line ultrasonic like the UltraFlo 1000 for hydrocarbon service instead.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
