Measuring flow rate on LabView using a AW-Lake EDGE Flow sensor

[Deerepete]

Hello All, 

I want to measure flow rate of our oil going though our motors set up on dyno stands in the lab. 

We have a Gear/PD flow meter with a AW-Lake Flow sensor pictured below. The output signal is 4-20mA that will be attached to the analogue input DAQ module ICP Con PET-7018Z or our I use our ICP Con ET-705 (not sure which to use). They connect via ethernet to computer but I think I could also do Modbus, not sure which would be easier? I am trying to figure out how get this DAQ into tabview? Then I want to convert the mA output to flow that can be displayed on a monitor using Labview.

Read the manual for your DAQ devices to learn the options they offer.

Then look for suitable drivers, either dedicated for your devices or (when they offer Modbus/TCP) one of those Modbus implementations available in VIPM.

Then it's just a matter of connect DAQ and your computer correctly…

The conversion from mA value to flow is (aka "should be") given in the manual of your flow sensor, so again: read the manual!

Btw. that sensor seems to provide a standard voltage signal, too…

Hi GerdW

can we use same DAQ Vi in LabVIEW as we use for NI DAQ as it is different ?

if we can use same DAQ then i think it can be done.

NI-DAQmx does not support such Ethernet-based DAq devices of 3rd-party providers…

The OP is using "ICP CON" devices: are you using them too?

I also need for this. i searched for its driver but did not find.

i hope the best way to use Modbus.

Thanks
