Good Questions to Ask
If you are researching a meter, the fastest way to get a useful answer is to tell us about the fluid and the duty: what are you measuring, at what flow range, what viscosity and temperature, what line size, and what accuracy you need. Those five facts drive almost every technology decision, as our selection guide explains. The more specific you can be, the more specific we can be in return — "a low-conductivity oil at 40 °C, 2-inch line, 60 L/min, ±0.5%" tells us far more 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.
What to Expect
Because this is a small independent project rather than a commercial help desk, we cannot promise a fixed response time, but we do read every message and prioritise corrections and good topic suggestions. We use the details you send only to reply to you and, where relevant, to improve a page; we do not sell or share them. If your question is really a purchasing enquiry — price, stock, delivery or a quotation — the right destination is the manufacturer or an authorised distributor, not this reference, and pointing you there quickly is the most honest help we can give.
