Low Flow Meters
Low Flow Meters
(OP)
I'm looking for a way to measure low flow, range 100-1000 cm^3 / hour (0.02-0.2 gallon/hour). The application is chemical dispensing where the chemical will be diluted in 10's or 100's of ppm, hence small flows. I've had limited success finding flow meter technologies that have such a low detection range, but I suspect they exist.
Any suggestions, either on general classes of meters or specific products/manufacturers?
Thanks!

Otherwise you have to go with a mechanical flow device. Here it makes a big difference in how many players you can choose from if your operating pressures are high. The main keyword search is "nutating disc".
The last big factor is accuracy. If there isn't a high degree necessary you can totalize chem pump pd cycles to estimate the rate to a fair degree of accuracy

DEA engineering, http://deaengineering.com/, makes a good mechanical type meter that is accurate, rated for high pressures, and cheap.
