Endress Hauser Prowirl Steam Flow Meter

02/18/2016 9:09 AM

Greeting,

We have installed Prowirl F200 DN80 on Saturated Steam, against following operating condition which was given by client.

Flow: 8000lbs/h , Pressure: 10 bar , Temperature: 170C, Line Size 6 inch

Applicator display the following outputs for these conditions

Meter Size: DN80

Velocity 41 m/s

Pressure Loss: 75mbar

After installation transmitter display measuring value as following.

Mass Flow 7193.13 kg/h ;;; is it mean the instrument size smaller then flow of 3628Kg/h big meter size required for 7193.13 kg/h

Velocity 94.15 m/s

Temperature 173.49C

Client have query about pressure loss and claim the instrument drop the pressure 2 bar boiler running on 9 bar and production area receiving the 7 bar pressure after instrument installation.

Could you share your views about this problem.

<...Could you share...views...>

Sure. Pick up the phone and discuss the problem with the equipment vendor. If it turns out that the instrument is the wrong size, then there are three possible outcomes:

  1. If the vendor selected the instrument based upon the supplied data, then it is the vendor's problem.
  2. If <...We...> selected the instrument based upon the supplied data, then it is <...We...>'s problem.
  3. If the Client gave the wrong data as a basis for selection, then it is the Client's problem.

Yes, we have discussed with our vendor they replied the instrument will work perfectly if you applied the flow 8000 lbs/h which was provided by client.

That was mistake by client with unit they were need to mention 8000kg/h not LBS...

Then run away laughing. Then obtain quotes for the correct unit based on the correct, revised, conditions, and give the Client a price for putting it all right. Simple!

In an ideal world perhaps - from 25 years experience I KNOW the Client will never get charged for this. Someone in the sales department will be concerned about future business, and <...We...> will bear the cost even if the Client was wrong.

Sometimes <...We...> can get the vendor to eat the costs, but even that is tough to do. They are very adept at finding something questionable in supplied data for sizing even if they goofed. Most times it is <...We...> that has to bite the bullet and pay for changes.

If <...We...> continue to do business with a Client that doesn't pay, then <...We...> would do better to find alternative Clients that do, before there is no <...We...> that can do business.

Better tell our sales department.

Actually, compared to a whole process system, one flow meter is chump change. What is a thousand or so compared to a million dollar charge?

Now if that part the OP is concerned about is the entire project, then you make the customer pay if you can.
