Dwyer Air Meter

[Wombat_101]

Brian or anyone...

Brian you recommended the:

As for the airflow meter, I use the Dwyer RMA-22. You can purchase them at
http://www.dwyer-inst.com/htdocs/flow/SeriesRMPrice.cfm
They are not 100% accurate, but close enough for our applications.

In another thread for the 200-1260, I have the 150-F2001 and wanted to know if I should get the same meter or a smaller one.

Also is the fitting the same as well,

Thanks,

That is correct, go with the RMA22, and the fitting.

[ghever]

I have some used ones in LPM if interested....$12 shipped

[AJtheReefer]

ghever,
I'm intersted. PM your information. I can send you a check or paypal

[AJtheReefer]

sorry, I didn't mean to hijack the thread.

Greg, if you didn't order and would like to order the used one from ghever. Please do so.

[meschaefer]

I just spoke for with Greg, and he just ordered one.

[UCanDoIt]

if there's any left, LMK. R these RMA-22?

[ghever]

I still have more left..and yes, its the RMA-22 in LPM... there is an easy conversion to SCFH...something like 1LPM = 2.1 SCFH(i have the actual number somewhere)

I have a question reguarding the meter. When you use it, the ball should stay at one level right. Mine is jumping from 5-15. Is that something wrong with my venturi?

[Wombat_101]

Mine pretty much jumps around from 5-7, but I see it dip down to 3 sometimes. However when I adjusted the valve so that it jumps mainly between 5-7 on my skimmer it looks like the skimmer is working much better.

[UCanDoIt]

On my A200 it is pretty consistent between 16 - 17.5

[Fliger]

I ran a Dwyer on my A110, and also on a Deltec MCE600 and the both bounced around quite a bit. I also ran a different meter on several Eheims on both H&S and Deltecs and they stayed within a tighter range. I dunno if its the Aquabees, or the accuracy of the smaller Dwyers.

[Wombat_101]

Is 5-7 good on a H&S 150-F2001?

[UCanDoIt]

Max would be 7-8lpm on 150 or A150.

[coqui1pr]

Well i got my rma-22 dwyer air meter today and tested my skimmer it has an aquabee pump and the meter reads between 3.5 and 4 lph here are some pics of it

Hey Nestor

Always nice to see my products at work, nice pics... I still have more of these guys, as you can see, they are used but look BRAND NEW.

Nestor, not sure which pump or skimmer you have but if its same as the other guys, that flow might be low. Is the black knob turned all the way open?

[coqui1pr]

Hi ghever i forgot to send you an e-mail so that i received the meter in excelent condition actually my skimmer has an aquabee 2000 pump i think that is working ok for my size skimmer which is rated at about 200 to 300 liters of air an hour my skimmer is a deltec mc500 so its working great i already downloaded the instructions for the meter and set it up and got my skimmer working better now i tested some of my local friends skimmers and they dont even come close to mine in air input definetly a great meter now i know how to properly set my equipment for the best use and performance of it.Thanks ghever

[saltyfun]

Anyone have one for sale? please pm me.

thanks,
Dave

[Dom_P]

A couple of questions...

Is the RMA 22 the right model for the A110?

And is there anythig else I need to hook it up?

Thanks
Dom

[UCanDoIt]

The RMA-22 is an excellent air meter for all the H&S skimmers.

[Dom_P]

Just got one of ghever's meters and am seeing between 4-5 lpm on my A110. Is that about right or is it low?

Dom

[UCanDoIt]

I don't have a A110, but I believe the highest air draw you'll be able to get is betwee 6-7lpm. Try tightening the air clamp down a little bit as sometimes when you close it down a little bit, the air draw is stronger.

[Dom_P]

Actually, had the meter slightly tilted before, now that I have it standing straight up, really is closer to 3 to 4 lpm...

I did try cleaning the pump last week with vinegar, still not getting the skimate I see in other pics... no real probs in my tank (no algae, etc). So I dont know if nutrients are just low.

Also pretty hard for me to skim wet at all. If I raise the water level too high, then the riser tube bengins to get water in it at the bottom vs. bubbles. I assume that isnt right. If I lower so that bubbles at the very bottom of riser tube, then skimate is pretty dry. Maybe i'll get 1/16" in the cup a day.

EDIT: The tank isnt very heavily stocked... just a couple clowns, a flame angel, a couple SPS and LPS. Maybe I'm just asking for too much skimate :)

[UCanDoIt]

On the white air clamp that tightens over the silicone air tubing, try tightening it a little bit at a time and then taking another air meter reading. Sometimes when you retrict the air just a little bit, the air draw gets stronger. Check your PM.

[FinsReef]

3 to 4 is a little low on the air. Make sure when you clean the pump that you remove the impeller from the shaft and soak both the shaft and impeller seperate. What you are describing is an indication of calcium buildup on the impeller bearings or shaft. claen the impleller bearings with a pipe cleaner, and the shaft with a scothbright pad after soaking in vinager.
HTH.

[Dom_P]

Thanks Brian

OK, I'll take a scotchbrite to it... how long would you say it should soak, when I did it last week, I left it there for about 1/2 hour?

Dom

[FinsReef]

Several hours if not overnight should do well.

[coqui1pr]

Well i have one of the same meters but the air input is ok for that pump since my skimmer uses the aquabee 2000 pump even thoug my skimmer is a deltec but it uses the same pump as the H&S A110 same wattage same NW as i have seen in pictures correct me if im wrong brian but as far as i have seen the aquabee pump that my deltec skimmer has is the same as an H&S just make sure that the impeller and the body of the pump are nice and clean and it should work fine.

Nestor

[FinsReef]

The Deltec version of the Aquabee 2000 is slightly different. It uses a larger needlewheel with some pins removed. More similar in size to the 2000/1 impeller diam. The H&S 2000 uses a samller diam impeller with full pins, none missing. IT also has the flap lover in the output compared to the Deltec. The H&S version should be between 5 to 7 lpm of air normally. IF the air decreases as the water level increases, it is usually and indication that something is impeding the speed of the impeller when backpressure is applied. That is generally calcium build up on ths shaft and ceramic bearings inside the impeller.

[coqui1pr]

Thanks Brian for the quick response i do agree that they should be slightly different but as i said to deltec when i noticed that the impeller of my deltec skimmer and the H&S were identical(on the smaller models using the AB pump 2000)not as described in the instruction manual of my deltec they told me that H&S and deltec share the same nw technology i was shocked beacuse for the money that i spent on my skimmer i wanted something different if you understand me not that im not happy with the performance of since it works awesome but i knew that i would definetly go with the H&S much less money and the same performance and great customer service i sent this pics of my pump to deltec when i claimed why the impellers looked the same on both brand of skimmers and got the answer above.

Thanks Brian

[Fliger]

Nestor you have a beatiful tank, I saw it here

http://www.all-reefs.com/inicio/acua...06-vt2635.html

[FinsReef]

Your impeller seems to be identical the the H&S version. I will post pics of the mce 600impeller and pump I have here later tonight so you can see the difference.
Along with the H&S version of the 2000.

[coqui1pr]

Thanks Brian i will wait for the pics.Also thank you fliger

Nestor

[FinsReef]

Sorry,
I will not have pic's, a customer picked the skimmer up today before I was able to take pictures.
The impeller in this thread was identical to the one on the MCE 600 that I had here.
http://reefcentral.com/forums/showthread.php?s=&threadid=740703&highlight=impeller
For an impeller with this diam, the holder for the output flap has to be moved further up into the output. It had the look of the inside of an Aquabee 2000/1 instead of the 2000 model.

[coqui1pr]

Cool but i wish mine would looked like that but as you saw mine looks as the H&S one dont know why but oh well at least is working excelent .

That is correct, go with the RMA22, and the fitting.


Does the fitting go in the top hole or bottom hole of the meter?

[FinsReef]

The fitting goes on the top of the meter.
Here is a few pictures that I was able to take of the impeller of the MCE600 I had at the shop.

Thanks Brian for the pic comparison as i can see my deltec pump for the mc500 aquabee 2000 and the h&s aquabee 2000 is the same dont know why but oh well what can i do about it.

Thanks again
