Osmolator Universal 3155 operation

[jhowell]

Hi Roger,

I'm considering the Osmolator for a 72 gal bowfront with a 20 gal sump. Evaporating about 1-2 gals per day.

I understand the optical sensor in the Osmolator is very accurate. In practice though, what is a realistic delta in sump water height between the pump-on and pump-off points - assuming a goal of keeping the water level at a near constant level?

Also, is there a minimum pump-on time?

Thanks,

John Howell

It is pretty much accurate to within a mm. The sensor has to detect a low signal for at least 8 seconds to trigger the pump on and then it will run for 10-15 seconds past full.
