Endress Prowirl F200 Steam Flow Meter

Endress Prowirl F200 Steam Flow Meter

Endress Prowirl F200 Steam Flow Meter

(OP)
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 suitable for flow of 3628Kg/h but 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.

RE: Endress Prowirl F200 Steam Flow Meter

What kind of answer are you fishing for?

You posted on the CR4 forum (link below) and neglected to reveal that the meter was sized for 8000lbs/hr, where as the process flow is in excess of 7,200Kg/hr. That's where the pressure drop comes from - excessive flow rate.

What's to say about it?

It's sized wrong.

Dear danw2, thanks for reply, we are not fishing actually we have selected flow meter against attached provided operating conditions.
http://files.engineering.com/getfile.aspx?folder=b...

and not neglected to reveal on CR4 as stated mentioned there "is it mean the instrument size smaller then flow of 3628Kg/h big meter size required for 7193.13 kg/h"

There is no other instrument installed on this line and having no body idea about exact figure of flow that's why they claim us your meter is measured wrong value which is 7193kg/h our production department needs only 4000kg/h may be they loss extra energy anywhere,
furthermore there is installed 13t/h capacity boiler which is connected on this line.

So how can we prove to client that your actual flow is 7113kg/h which is measuring on transmitter display and they provided us 8000lb/h for meter selection.
