I am a grad student constructing a pump and heat exchanger lab for the undergrads to perform tests with. so basically I am trying to measure 2 flow meters and rpm of the pump (square wave and need the frequency of all 3) as well as 4 thermal couples and a differential pressure sensor. So i know that logud can measure and record the analog voltage signals of the thermal couples(with ljtic amp) and pressure transducer. But the flow meters are rated with pulses per liter. Our university has labview on all the computers but i have no experience with it or much programming background other than matlab.
I have played with all the U3 examples and have an idea of how everything works with the different VI's used to find/call up/run the labjack but i still feel like im in over my head.
over view of the experiment
--cold water flows through a heat exchanger(measuring the temperature in and out of the HX and also the flow rate)
--hot water is pumped from a reservoir through a heater ,through the heat exchanger(measuring temp in and out of the HX and also pump head/pressure and flow rate)
I have the working test setup with sensors in place, its just creating a user interface for them to record data in the correct units gpm/lpm thats getting me. Building a interface this large with all the different LJ vi's in labview is way over my head. can anyone help or point me in the right direction. I have to build and program 5 of these before the end of the summer.
