Does the FL4513-V flowmeter have 1/4" NPT female AND 1/2" NPT male Input connections. The website shows the 1/4" NPT F. Most of these style flowmeters have a smaller Female thread on the inside and a larger Male thread on the outside of the Input Ports.

can this type of flowmeter be used for oxygen and propane
Asked by: JABM
Thank you for your inquiry! These flow meters can be used for a variety of different gases including oxygen and propane. Since these models are scaled for air, the readings will have to be corrected by factoring in the specific gravity of the other gases.
