This page outlines the information needed to research a flow meter and points to the relevant technical guides.
Flow Meter Reference is an independent educational resource, not a vendor. Price, stock and supply questions belong with the relevant manufacturer or an authorised distributor. These guides explain the technology and the specifications used to compare it.
Good Questions to Ask
Research begins with the fluid and the duty: what is being measured, at what flow range, what viscosity and temperature, what line size, and what accuracy is required. Those five facts drive almost every technology decision, as our selection guide explains. A specification such as "a low-conductivity oil at 40 °C, 2-inch line, 60 L/min, ±0.5%" is more useful than "a flow meter for fuel."
You may also find your answer already written up in our references on flow meter types, positive-displacement meters, electromagnetic meters or calibration and accuracy.
