What equipment do I use...

[Rahms]

Hello NI Community,

I need your advice and expertise.

I would like to control the flow of water (mass flow of 0.01 Kg/s)  using LabVIEW ideally via usb.

My problem is I don't seem to be able to find any mass flow valves for liquids that have a computer connection and then be compatiable with LabVIEW.

Can you recommend some manufacturers, websites or even products that fit my specification? Does NI have something that I could use?

I know I haven't provided much to go with, but if someone could point me in the right direction it would be very much appreciated.

You will probably not find a mass flow valve with a computer interface, but there are lots of mass flow valves with analog voltage controls (0-5V or 4-20 mA). Then if you purchase a USB module from NI with the appropriate analog output to match the valve you will be in business.
