LIquid Flow Meter 828 and 5666

by JB94 on Wed Dec 01, 2021 1:22 pm

So I've been looking at getting either liquid flow meter 828 or 5066 but both are rated for 1-30LPM. I work for a medical device company and we're looking for flow meters for a production model but have to test them first. This issue is our device operates in mL. Can either of these flow meters detect flowrates under 1LPM?

Thanks

That'd be outside the design of the meters. They both work by having the flow turn a wheel, which creates pulses that are sensed and turned into flow rate. With low flow rates, there just isn't enough flow to reliably spin the wheel and produce an accurate signal.
