Apex Fusion Dosing Pump Coding

[Ligershark]

Can someone please confirm the following code for my dosing pump.

I want to run the dosing pump for 5 minutes every 90 minutes throughout the entire day.

Fallback OFF
OSC 000:00/005:00/085:00 Then ON

Yes, but you might not like the outcome. The sum of dosing time and wait time in hours should be divisible by 24 (1 day). You have 1.5 hours here.....There is a better way to do this.

My doser is .15ml/min. I need to dose 9ml/day at the moment. I could dose 3 or 4 min every 60 min but that will give me too little/too much supplements.

I understand what youre saying about the 24 hours. Thank you for confirming the code.

Here is how you do 9ml a day

Nope, you have that backwards. The sum of all three times in an OSC should be evenly divisible INTO 1440 minutes (24 hours), not BY 24 hours. And this only applies if you want to be able to predict and know exactly when each OSC ON time will occur.

Also, 1.5 hours/90 minutes total OSC time sum is evenly divisible into 24 hours.... there will be exactly 16 doses per day.

oops bad math. 1.5 is half of 3 which is dividable by 24.

My doser is .15ml/min. I need to dose 9ml/day at the moment.

Looking at the info in the two above quotes, it doesn't add up.... the programming will not give you the desired total daily volume. 0.15ml/min * 5 minutes per dose * 16 doses per day = 12ml/day

I could dose 3 or 4 min every 60 min but that will give me too little/too much supplements.

OSC values are in MMM:SS format - you are not limited to using whole minute values; you can go down to the second.

It would be easiest to just use hourly doses.

Your total desired volume is 9ml/day. Divide that by 24 hours to get the hourly dose volume.... 0.375ml. Then figure out how long it takes to dose that amount @ the pump's flow rate... 0.375 / 0.15 = 2.5 minutes. In MM:SS, that's 2:30, which is the ON time required per hour. Subtract that from 60:00 to get the OFF time to be used in the OSC, keeping the total sum at exactly 60 minutes... 57:30. So, the OSC to be used for hourly dosing in your case is:

OSC 0:00/2:30/57:30 Then ON

I developed the online dosing program tool ngvu1 gave you a link to, but it won't work in your case - I wrote it for use with dosing pumps typically used in the hobby, and your 0.15ml/min pump is not typical ;) The tool will not accept such a minuscule value of 0.15ml for the pump flow rate, so that's why I went through all the math for you.

Ya did it again, my friend --- it's not BY 24... it's INTO 24 ;)

Following along as about to hook mine up and clueless on all of this!

Great so now it's bad math AND English :-)
