Now i'm doing a project with labview which is about how to regulate the pressure inside the tube. Each time when we inject fuel into tube and at the other end we have another drive to drain the fule in order to keep the pressure constant inside the tube. But this two actions are not happen simutaneously. when we inject for a while and notice the pressure in the tube is out of the range we will began to let the empty valve to open. I have an idea but it's not so accurate. Is there any labview build-in regulating stuff that can accurately control the filling and emptying process? i have attached my vi, that is just a simple idea, the drain and fill vi is to generate pulse to control injector action. Right now we can not decide how big signal should give to injector that can give very accurate results. Is there any way to accurately offer pulse as we want. If some one have any idea about it, give me a hint is also ok.
Thanks in advance.
