A+++ quality
I have a lot of flow meters including chinese and american models, the quality of Omega is greater than all of them. Even the box of the product is more atractive and have a very good presentation.

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.
Thank you for your inquiry! The FL4513-V will has both 1/4" FNPT and 1/2" male NPT connection sizes.
