how will i link flowmeter sensor and labview

[sgirgin]

Hello everyone,

I am new in this forum and alson in labview.I have a flowmeter sensor, I made cable connections bewteen the sensor and DAQ(NI-USB 6229) The question is what am i supposed to do to read the data on sensor.I just want to measure read the flowmeter sensor and dont know how to construct the labview diagram.I searched on net and learned that I have to do something with counters to convert square signal to a grapgh.and also I searched some codes about it but there must be an easy way to do this it ooks too complicated.In attachment I am sending the vi file.

Can you please help me because I have limited time..

Thanks in advance.

Why did you attach a VI that writes out an analog output rather than a VI that actually reads in a signal?

What type of signal is the flowmeter putting out?

Did you look in LabVIEW help?  There are dozens of examples there for reading different signals using DAQmx.

I know i have to do it with a digital output but because i am new in labview and dont know the types of codes which generates analog or digital.Tehn our solution is easy i think with a digital output.The sensor is giving square wave.But firstly i have to consruct the labview code for it.

You don't want to generate a digital output.  You want to READ a digital input.

Ok then what am i supposed to do in front panel or block diagram could you please tell me?

You could also use a counter to measure frequency. Examples for both - Help> Find Examples and look under Hardware Input and Output for DAQmx.

thank you, i will try it.if i cannot not progress will write again

Checking for examples in help?  What a novel idea!  If only someone had suggested that back in message #2.
