Inquiry (采购产品): Looking for the right meter I am quoting an customized equipment for customer in medical industry where need to measure a small volume of water displaced in a few second (5-20 cc 7 secs). The flow is not continuos. I have to switch the flow on/off with a solenoid valve and measure the displaced volume between switchings. The shot size varies from 5 to 20 cc. I must be able to switch the feed valve in 5-20 cc shot sizes +/- 0.5 cc or less. The time also varies between 2-7 secs for any shot size. So the flowrate is probably between 0.15 and 0.6 LPM. The pressure is also an issue. The water being measured is coming out of a rubber bladder previously filled with 100 cc @ 20 psi. So, the pressure will drop as the bladder gets drained. What is the best way to measure that volume as precisely as possible? Can I use a flowmeter with a pulse train output, and measure the volume by counting the pulses electronically while the water is flowing? Do you have any product which might fit my application? Please let me know your comments/suggestions Thanks in advance for your assistance. Juan M. Vargas jmvargas@racsa.co.cr **** Hidden Message ***** Juan M.
