Where can I find a flow sensor that can monitor the liquid flow rate of refrigerant inside of a 1/4 inch diameter copper tube?

 

If your tetrafluoroethane is in a liquid state, EESiFlo has a number of ultrasonic products which will accurately measure flow through 1/4 inch
copper.

Contact me off list for more information.

I know of a small thermal flow meter that is available for this service. We also offer our Series/LFE meter. The Series/LFE is a laminar flow
element DP device. Either one will work on very low flows. Contact me if you would like more information.
