Flow calibration using weighing scale

Thread Starter

Just would like to ask the percentage of error in calibrating flowmeter using weighing method.

Standard Plan

We build these systems for our own use as well as offering them to customers. We have built gravimetric flow calibation systems from very
low flows (<100 cc/min) to rather high flows (>2500 GPM). The overall accuracy can range from pretty good (<2%) to very good (<.25%), mostly
depending on the instrumentation used. NIST and others have papers dealing with the construction specifics and accuracy of these systems. If you are planning to build your own system I suggest obtaining these papers and following them explicitly, or call us for more information!
