M6S1K3 Posted April 11, 2015 Share Posted April 11, 2015 I have two 1.1mL BRS dosing pumps that I'm assuming I need to calibrate. I see the hole in the top right that has a "+-". How do I know if it's calibrated to 1.1mL/ minute? I appreciate the help. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
jolt Posted April 11, 2015 Share Posted April 11, 2015 You let it run for several minutes and measure how much was pumped divided by number of minutes Hook it up to some RODI water in a tupperware and let it pump into a measuring cup Link to comment Share on other sites More sharing options...
M6S1K3 Posted April 11, 2015 Author Share Posted April 11, 2015 There is nothing behind the "+-". How do I adjust/ calibrate?! Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
FarmerTy Posted April 11, 2015 Share Posted April 11, 2015 +1 to Jim. There really is no need to calibrate them for the most part. I would just do what Jim suggested and find out what the dosing rate of your unit is now and then just program their function off of that. If it's dosing 1.3 ml/min now, then program your dosing regiment with that rate, if it's dosing 0.9 ml/min, then do the same with that number. Just my 2 cents.

M6S1K3 Posted April 11, 2015 Author Share Posted April 11, 2015 I appreciate it. Yea there is no way to actually calibrate. But what you said Ty makes sense. Thanks all for the help! Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

M6S1K3 Posted April 11, 2015 Author Share Posted April 11, 2015 Haha. I see how Jim tried to get me to that conclusion. I had an extremely kind week so you spelling it out helped nudge me closer to jims words haha. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

madsalt Posted April 11, 2015 Share Posted April 11, 2015 Run the doser for 10 minutes into a cup that is marked in ml. Once you are done that will give you how many ml/min. So if you hit 10ml in 10 minutes you are at 1ml/min. Make sure you do 10 minutes to get an accurate number. Link to comment Share on other sites More sharing options...
M6S1K3 Posted April 11, 2015 Author Share Posted April 11, 2015 Usually my posts need deciphering as I have trouble verbalizing what's in the ol' noggin. So that's Ty. And mad salt. Will do! Thanks Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Reburn Posted April 11, 2015 Share Posted April 11, 2015 All this calibrating. They come pretty closely calibrated. I would just set it a little low to what your appropriate dose is and wing it. Link to comment Share on other sites More sharing options...
madsalt Posted April 11, 2015 Share Posted April 11, 2015 I did the calibration on mine and I hit 1ml/min Link to comment Share on other sites More sharing options...
M6S1K3 Posted April 11, 2015 Author Share Posted April 11, 2015 Problem with me winging anything is I have horrible luck and somehow Id be dosing like 15ml a minute (yes i realize that's high but...) and everything would die haha. And I bought them second hand but new in box. Except one came without a mounting bracket. So I have to engineer something. I called brs and they can't even get them.

jolt Posted April 11, 2015 Share Posted April 11, 2015 To what Reburn said, it's important to measure alk frequently when dosing. That's the best way to get a handle on how much to dose. I measure alk daily and adjust my dosing time almost daily (+/1 a second or so typically), based on current alk consumption. Larger tanks probably can get away less often. Mine is 32 gallons.

M6S1K3 Posted April 11, 2015 Author Share Posted April 11, 2015 Ok good to know. What do you use to test? I've ordered a hanna alk checker. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
jolt Posted April 11, 2015 Share Posted April 11, 2015 Yes, most folks consider the Hanna a great tool. Also, I would add that I have marked my dosing containers in 50ml increments and I watch the consumption there too. I've learned that over time my second doser has started dispensing less than the first so I adjust it so that consumption on both is roughly equivalent over a week.

M6S1K3 Posted April 11, 2015 Author Share Posted April 11, 2015 Awesome. I'll do that as well Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
