Use FM350-2 to read Sensus Pulser 0D07-24S

Dear All,

I am trying to read signal from water volume meter brand SENSUS, using Pulser OD07-24S.

I use ET200M remote module 6ES7 153-2BA02-0XB0.

Last time I read the output signal directly using DI Module 6ES7 321-1BL00-0AA0, but cannot capture the pulse signal at all. Then I realized that those DI Module is using 200ms cycle time and the Pulser sensor pulse width is only 135ms and pulse pause time is 585ms (for 5m3/hr flow, faster flow resulting shorter pulse width). Mine is running on average 8m3/hr = 100ms pulse width and 350ms pulse pause time.

So the supplier of the Pulser sensor advice to use this FM350-2 counter, but they aren't sure whether this FM350-2 is compatible with the sensor.

Would anyone mind to help me to make sure whether this counter module is the correct way to solve my issue? Or maybe anyone is ever experienced this problem before?

I also attached the pulse widht chart vs the flow.

Thanks,

Aditiya.
