Create a linear relationship

[Allard171]

Hello,

I have a voltage input on my DAQ device from a volume sensor, and want to link this to the actual volume. Is there an easy way in which I can say that 0 Volt should be equal to a volume of 0 liter and 1.5 Volt should equal 20 liter and have a linear relation for the values inbetween?

Hi Allard,

apart from DAQmx scales you could use a simple equation like

   flow := 20/1.5 * voltage

Seems easy to implement…
