Flowmeter FS300A on Wemos D1 Mini, How to calculate?

[Tobi993]

Hello together

I have a Wemos D1 Mini and a Flowmeter FS300A connected.
The yellow signal line is connected over a voltage devider on Pin D5.

At ESPEasy a have a device created Generic Pulse counter.
I get some values.

So far so good.

But does anybody know how to set the parameters at ESPEasy?
Debounce time, Intervall?

I have a rising edge set.

The FS300A will calculated: Pulse Frequency = Flow* 5.5
When I have to total pulses dived by (5.5*60) = Liters total?

What's about Count and time?


Thank you!

Maybe have a look here:

Yes, I know.

I think I can calculate Total pulses / (5.5 * 60) = Total Liters

But what's about count and time? What's about Intervall time?

Hi !

My experience with those flow-meters is the documentation is never right (or I never found the right documentation !!) ! So I always calibrate them after the espeasy setup is operational : I send 10 or 20 litres though the flow-meter with a funnel, making sure to send them quick enough as they are not linear on low flow. After that I know by what to multiply the total value to match my 10 litres.

Count is the number of pulses between two readings
Total is the number of pulses between two esp reboots
I don't know about time : ms between last two pulses ? something else ?
