Fuel Flow Indicator Frequently Asked Questions
Question number FAQ-0826
The instruction manuals for each model in the FP series show that there are SIG1 and SIG2 inputs. If there is no need to detect backflow of the measured fluid, is it sufficient to connect only SIG1?
There is a problem.
Since SIG1 is output in both forward and reverse rotation, accurate measurements cannot be obtained by connecting only SIG1.
To measure correctly, a circuit is needed to process SIG1 and SIG2.
