multidirectional flow

[StirCrazy]

Oh and out of curosity can you post or PM me a price on the 4 port unit that would have a delay function.

for the delay, is it adjustable? I wouldn't want anything like a wave maker but being adjustable between say 1 hour and 6 hours in 1 hour incroments would be cool. I don't think having an off time is nessasary as when the switch over occures there will be a time period of random flow while the water flow is slowed down and reversed.

Airotronics units come with different values,all adjustable, you can easily obtain a timer that gives you the delay values you require,from seconds to hours, your choicethere are only a few options to get what you need, using a 1 rpm motor, or any rpm motor there will be no random activity, Bean has a better alternative.
The valve and pump simply go into their own closed loop cycle as that happens, remember the motor will move and stop (in 15 seconds) at the desired location until it sees the time out and then moves to the next location this isn't a progressive move as in a typical OM4.

as for the timers, do youmean that you have to substitute different timers or is there an adjustible one (weather it be by dip switch or screw)

Don't know who bean is but I think you miss read what I ment. the random activity I was talking about wasd of the water in the tank as it reverses direction. so once the inlet/outlet switch the water will still be flowing opposite to the new set up. so it will take a bit of time for the water motion to stop and switch directions. during this you will have some random water movment in the tank.

They are all adjustable but come in ranges to suit your needs.

"THCU-E offers three time ranges: 0.1 second to 102.3 seconds in 0.1-second increments, 1 second to 1023 seconds in 1-second increments, or 10 to 10230 seconds in 10-second increments. Ten-position binary dipswitch is easy to program."

Ah now I understand what you mean, yes there will be the transition time, and random things going on for that time frame.

hmm so the timners don't go long enough for a natural tidal cycle. would nee up to about 21600 seconds to get to six hour mark, but 2.7 hour cycle would probably be fine.

damn you.. I was going to hold off a year or two befor I start building my next set up now you got me thinking

I'm sure if you wanted 6 hrs it could be accomplished easily, you could likely invest in a small PLC and get someone to program it to run for 6 and a half hour cycle which would repeat, that way the high and low tides would change daily just like in the natural world.
