soulblood Posted March 28, 2014 Share Posted March 28, 2014 Hi there, I'm using labjack u6 to obtain a voltage output from a flowmeter. But the readings are different as I connected the output to different LJ AIN ports (varies from 1.1V-1.8V for different AINs). Does anyone have some suggestions on this? I'm quite confusing now.. Thanks, Ryan Link to comment Share on other sites More sharing options...
AzeoTech Posted March 28, 2014 Share Posted March 28, 2014 What is the make/model of the flowmeter? Assuming the flowmeter outputs an analog signal, is powered correctly and is linked to U6 GND, and the flow meter is running at a constant rate, then the voltage should be constant. It is easy to prove if the U6 is working by routing a short jumper wire between DAC0 and AIN0, or AIN1 etc -> Then using LJControlPanel change the voltage of DAC0 to a known value, and see if the AIN0 or AIN1 inputs report the same value. This process is covered in the U6 quickstart:http://labjack.com/support/u6 Link to comment Share on other sites More sharing options...
LabJackSupport Posted March 31, 2014 Share Posted March 31, 2014 Provide a link to technical details for the flowmeter. What sort of signal do you expect? A dc or ac voltage related to flow? Is the magnitude related to flow, or frequency related to flow, or both? Link to comment Share on other sites More sharing options...
soulblood Posted April 12, 2014 Author Share Posted April 12, 2014 Sorry for the late reply. I was using AWM5101 flowmeter http://sensing.honeywell.com/index.php?ci_id=3108&la_id=1&pr_id=25824 It's giving an analog output. Link to comment Share on other sites More sharing options...
