What LibertyCES's vendor documentation shows

This cell matters as an exclusion, not an inclusion: the corpus's own specs rule out most of the flow-instrumentation catalog for this family. Signet's 2551 and 2552 both state a 20 µS/cm minimum conductivity, so they physically cannot meter a hydrocarbon. What is left is clamp-on ultrasonic (zero wetted parts, so compatibility is moot) or a fluoropolymer in-line ultrasonic. Signet's recurring guidance also applies: for multi-material systems the maximum temperature/pressure spec must always be referenced to the component with the lowest rating.

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'
