Flowmeter with two 4-20mA outputs to a PC
Flowmeter with two 4-20mA outputs to a PC
(OP)
Please let me start by saying I am not an electrical engineer, I am a software developer. I have a current project where I need to connect a Flowmeter which has two 4-20mA outputs into a management system (A specialized PC). I need to be able to differentiate between the two inputs.
The PC has only a single RS232 or an Ethernet port.
I will attach the specification of the Flowmeter to this posting.
I have tried searching the Internet for 4-20mA convertors and have found quite a few, but I feel out of my depth in determining which is the best way to go.
Any help would be greatly appreciated.
Thanks
Dave

RE: Flowmeter with two 4-20mA outputs to a PC
You also need a 12,15,or 24V DC power supply that can provide 200mA or more. That would be a 5W or greater supply.
You will be looking at the "Connection to a PLC/Recorder, separate supply."
Hunt up what will work for you and let's see it.
Keep in mind that inside a PC is 12VDC and that can also be used for the supply as it is more than adequate for your transmitter. So if a 4-20mA 'adapter' exists that provides 12VDC output power that would be a good solution also.

I'd keep away from serial ports as fewer and fewer computers seem to have them, especially laptops.
