If you wish to use AUX 5 for pulse counting, you must set the AUX5 option for pulse counting then click the "Reboot" button (all under the ECM-1240 Setup tab). You can cycle the power to the ECM-1240 instead of clicking "Reboot".

If this is not done, any stray noise on the AUX 5 input will be interpreted as AC current and the WS counter will increment at a high rate.

You can check with this company. They do have a low-cost water meter: http://www.buygpi.com/minomess130reside ... meter.aspx

The Gallus 2000 gas meter may be used for natural or LP gas and has a pulse O/P

We are using the IMAC Ester AMCO G4 http://www.imacsystems.com/bkg4-g4-meter.pdf

What is the approximate cost for these? I should note that Ben will include options for gas and water in the new version of the software.

This place has them for about $160. They have other larger, more expensive ones, too. They are also on eBay.

If you "back up" a page or two on the link that jfisher provided to get to the listing of all the gas meters that company offers, it shows this one as being "indoor only".

Paul,

Since I don't know the pulse duty cycle for the flow meter (so I don't know how "fast" the relay needs to be), and I don't know if the flow meter or softener electronics would be negatively affected by the draw on the circuit that the relay coil would cause, my best chance may be the "diode" route. Is it really as simple as the diagram looks? Just run a tap off the flow meter's ground lead to the AUX5's ground terminal, and run a tap off the flow meter's signal lead to one side of the diode and connect the other side of the diode to the AUX5's "AUX5" terminal?

Regarding pulse duty cycle? What are the requirements as far as minimum pulse width, etc.? Does it matter if the pulse width changes due to increase/decrease in flow?

How's the divider circuit diagram coming along?

Thanks,
Ira

If you are using the pulse divider circuit, the duty cycle doesn't matter. I have attached the pulse divider circuit. There is less than $2 worth of parts used in this circuit.

Thanks Paul,

I think I can probably build these.

I am a little confused though. The first diagram is for the isolator. The second is for the divider. Do I use both if I want both isolation and a divider, or does the divider circuit have isolation built into it, too? If I need both, how do they fit together?

Thanks,
Ira

I should have explained this..... The opto circuit is not related to the divider. I included the opto circuit because the one in an earlier post had not component values assigned.
