The quality I'm measuring it's Penetration. As far as I know there is no analyzers for that quality. Even so, I have to take samples to certify the quality. Putting a bucket it's not the solution, because when the asphalt gets cold it solidifies; and then I create a problem by taking out the...
Good night:
The way that I am taking hot asphalt samples in the refinery has a big impact on the environment because when the sampler is being displaced, all the asphat goes into the ground, and will accumulate until it goes to the ground, later going to sea. What are the best practices for the...

If you're designing you have to assure that there is a straight run enough for your meter.
I meant that the orifice should be upstream the control valve. In order to don't short the straight run of the meter you have to assure that there is enough straight pipe (I guess is 5 pipe diameters...
The function of the control valve is to control the gas flow to a stripping tower.
I've seen a lot of PID's and the flow measurement it's always upstream the control valve (Liquid and gas cases). I wonder the reason and I think it's because we calculate the orifice of measurement with a...
Hi Hardy:
In this web page you can find some information about the steps to follow in designing a stpe valve. It can be very helpful.

Tell me if it was.

THE ORIFICE SHOULD BE LOCATED UPSTREAM OR DOWNSTREAM OF THE CONTROL VALVE??? WHY ?? WHICH POSITION IS MORE ACCURATE?? THE POSITION AFFECTS MORE IF IT IS A LIQUID OR IF IT IS A GAS??? WHERE CAN I FIND SOME INFORMATION??
