Pulsecount


Makada Sep 25, 2020 02:15 PM

Hi,

I would like to know the following:

I have a scanrate of 250ms.

Within that scanrate i have two pulsecount functions which i want to be read in seconds.

Am i right in thinking when i set the pcoption to 1000(ms), those sensors are read every second instead of every 250ms ?

Like so: 

Pulsecount(Rain_mm, 1,1,2,1000,0.01,0)

Without averaging the actual output of the sensors?

With kind regards.

Using that option in PulseCount() will give you the running average of the frequency in Hz. The multiplier would then be applied. I think that will accomplish what you want.

Another option is using TotalRun() with a count of 4. That would totalize over 4 scans.

Hi JDavis,

Thanks alot for your input.

Is it possible to have the rain sensor to connect to other connection on the cr1000 to have it working inside a slowsequense instruction instead of the pulse connection on the cr1000?

Because a pulse sensor cant be used on a slower scan.

On the c channel ive heard, but i dont know how to connect.

"The Uout1 and Uout2 digital outputs are short-circuit proof high side switches (12V) with integrated pull-down resistors.

The length of the output pulse for tipping bucket simulation is typically 50ms.

The type of precipitation is transmitted on output Uout2 in the form of different frequencies."
