I have to check calibration at a site that has Ovation 3 grade blenders. All grades are blended so there are no straight products being dispensed. Am I right in thinking that if I have to calibrate one of the Ovations because one of the blended grades is out of whack that I'd have to set the blend ratios so that each of the 2 meters is dispensing only straight grades? So that I'm not trying to calibrate a meter that's only supplying one portion of a blended grade? That makes sensse at the moment, but can someone confirm or deny that??

With the remote hit Clear, it will tell you the ratio (% of high).
Dispense 5 of each feedstock. Once calibrated, and you have to know how to open the door on the WIP to do the calibration, dispense 5 gallons of the blend grade at about 2 or 3 gpm. This is what Handbook 44 refers to as a Special Test.
If you don't know how to use the remote or know how to do the calibration get someone who does. It's not worth the trouble you can cause. |

| I'm pretty good with a remote. I change the blend ratios and verify them every Spring/Fall, but have not yet had to calibrate this site. The thing with this site is that there is no grade select for a feedstock because all 3 grades dispensed are a blend of the 2 feedstocks. It's not like a regular UNL/MID/PUL setup where UNLD and PUL are feedstocks and MID is a blend of them. There, all 3 grades are blends of straight gas and ethanol feedstock. |

What is this setup? They get their own straight ethanol as a feed stock and straight gas and mix their own? That sounds like a disaster waiting to happen. One loose fill adapter and a good three day rain storm and you would have a really strange Phase separation I would think. |

| Mike you are correct, you will need to change the blend ratios to calibrate. I have an ethanol blend site that I have had to do this at. I also close the other fire valve to ensure I am on the right product. |
I can't fix stupid, But I can sure charge for it. |

Thanks Smelly  I kinda thought that was the case but as you can tell, I'm not primarily a Wayne tech, and this is the only one I've seen with this setup. Good idea with shutting the other shear valve, I'll make sure to do it. Thanks again |
