Are the AWC DC pump sets available to order from your web site?
how can you use the AWC dc pump setup for accurate usage i.e precise exchange of volume?
the ATO dc pump is a regular impeller pump?
Set is already released - within one week it should be available to order thru Resellers.
About your question:
It's very easy. Before you will start using AWC DC set you need calibrate for waste water DC pump. To do this you need 1000ml cup/bottle and you need follow calibration procedure(it should be done when al tubings are installed/cutted etc).
After calibration procedure doser know how much time it was needed to pump out 1 liter of "waste water".
This procedure is very accurate and after our tests we never saw difference higher than 4-5%(for DC pump it's very accurate result).
Fresh water pump will refill water until old level will be reached(previously set by optical or floating water level sensor).
Until AWC will finish his work ATO(aut top off) is disabled - to protect against not wanted freshwater(without salt) refill.
This module (together with compatible software/firmware) is actually released.
Any questions - please follow our sponsor thread on ReefCentral.
ATO DC pump is regular impeller DC pump(the same like AWC DC set pumps).
They are speed controlled by dosing station.
