@btrueblodd - It is the opposite that is occurring. Thank you all for your response.

The pipes are the same 6 inches all the way from upstream to downstream. @micalbrch- we cannot perform that type of experimentation.

We have tried swapping them as well over the years and the difference is still the same. I have another response from a different group that I may try. I will check the transmitter card calibration and transmitted signal. I may need to boost or lower the transmitted signal on one or the other...

It is both a Rosemount 8800 vortex flowmeter and send off to a third party vendor for calibration using a proofer meter calibration system. It was like this from the beginning and never agree at all.

Thanks gentleman, I received good answers so far. Anyway, the pipe is 9 years old. The meters are calibrated annually so I am confident that they are both correct. The pipe does not show any signs of deterioration.By the way I forgot to mention that it also has a 40 micron filter right after the...

I did that already. We verify the 9.6 mile pipeline and checked the P&ID. The pipeline configuration is straight and simple. One long pipe with flow meter on the upstream and another flow meter downstream. Flow meter upstream reads 225 gpm and the flow meter downstream reads 166 gpm. No leaks on...

What could have cause this to differ in flow? Our waste water centrifugal pump is discharging water at a normal rate, there is an installed flow meter on the upstream of the waste water disposal approximately 15 feet away from the pump discharge and the flow rate is 225 gpm. On the downstream...

Thank you guys for the response. This helps a lot. Thanks again.

Can someone explain the purpose of the target inserter that are used during steam blow? Are there any specific type of material to be used as a target inserter for steam blow?

What is the Hydraulic Institute acceptable vibration level for a 48” vertical pump that runs at 710 rpm and moves 60,000 gpm?

I wanted to get information on what is the standard location to install the anti-flash valve on the boiler feed pump? Our boiler feed pump is equipped with an ARC valve connected directly on the discharge side. I am not sure if the ARC valve has an internal antiflash valve installed in it...

I have a Circulating water system that uses raw water on our facility. The P&ID shows an ID of "15 NB Sch 160"on some piping. Does anyone know what is "NB " stands for? I have look at the manual and system description but I have no luck on finding what it means.

Does anyone has an experience on the HRSG design and configuration? The MAWP and the Desgn Press is the same on our Superheater and Drum section as well as the Reheater section of our HRSG. I ask the manufacturer why they did not place an allowance on both section and they quoted me the ASME...
