Hello Friends;
I have a Flow meter which installed on the gas line.
Problem is that i connect it to the GE PLC 90-30 series high speed counter module to read the frequency crossponding to the flow.
But the voltage amplitude is too low to unable to read the values.
Now it gives me 315 Hz at 300 mV.
Please help me how i just amplify the voltage without disturbing the frequency.
There are two wires come out from the flow meter. I see that signal on the oscillscope almost between sine and square wave shape.
Please help me how i build the circuit to amplify the voltage from 300 mV to 4 to 5 V.
Thanking you i will remain
Regards
