Howdy!
I wasn't sure which category to throw this one in, so I hope this is a reasonable fit.
A local fish hatchery recently installed a new drum filter machine for their streambed. It came as a package with the filter motor, pump, some other stuff, and a small control panel. Their system is up and running just fine, but they called me out to look at the viability of installing a little counting device that records how many times the drum filter activates in a normal cycle.
The drum filter runs based on the action of a float, and operates for an adjustable period of time (I think they have it set at 30 seconds now).
There is already an hour meter installed in the panel which I suppose you could mathematically use to figure out how many 30-second intervals have occurred, but they said they want a simple counter that increments by a value of 1 each time the filter starts. That way they can walk in, glance at the counter, and walk out without having to crunch numbers.
I haven't put much thought into it yet, but I figured if I can find a counter that will increment by 1 each time a voltage is applied to it, then I can just tie it into the control wire that starts the filter motor. The controls are 120 VAC. Does anyone have any suggestions on where I could find a device like this?
Thanks!
