No pulse output from the flow meter.
● Pulse mode and pulse equivalent can be modified in the parameters, refer to the manual for details.
● Active pulse output (PNP, NPN, OC hardware can be commissioned at the rear terminal block), refer to the manual for details.
● Measure the voltage between FOUT-C and COM with a multimeter, if the meter has flow if it reaches 0V (low level) or 24V or so (high level), it means that the meter has no output and the circuit board is faulty;
if it reaches a voltage between 10V-12V, it means that there is output (power supply 24V, half of the voltage is measured by the multimeter when there is output), the customer can check the acquisition equipment if there is no problem.
