I have not done much with pulsing at all but have quick job I need to get done soon.
It's a totalizer that I will configure to pulse out to turn some equipment on after so many pulses have occurred.
The meter outputs 24vdc, I was told I need to have the pulses close for a minimum of 25ms for there readings. I know to configure the other stuff like gallons per pulse and such.
My main questions are
- do I need to use a certain type of relay for pulsing? They requested a dry contact pulse so imagine I am just going to be pulsing that 24vdc to a relay and use the dry contact side for their two wire..
- the other question is if I do use a relay and let's say the reaction time is 20ms before it closes. Do I have to figure this into anything on the meter or the number I give the customer for ms?
