Hi all,
I have two flow meters in series and I have to acquire flow rate data from each, simultaneously.
--FLOW METER 1: hall-effect flowmeter (see attachment). Its output are DC square waves (digital output) whose frequency is proportional to flow rate.
In order to acquire from this meter, I have a NI-9411 card.
In SignalExpress I did: Acquire Signal >> DAQmx Acquire >> Counter Input >> Frequency
--FLOW METER2: electromagnetic flowmeter (TOSHIBA, see attachment) model GF630/LF620, whose output is an analog signal, whose voltage is proportional to flow rate.
In order to acquire from this meter, I have a NI-9203 card.
In SignalExpress I did: Acquire Signal >> DAQmx Acquire >> Analog Input >> Voltage
Both the cards are in a NI cDAQ-9174 chassis.
My question is: Is it possbile to acquire signals simultaneously from flowmeter1 and flowmeter2 and than download data in .txt?
Every suggestion would be more than appreciated.
Thank you in advance.
Best wishes
Agostino Ghetti
