First, thanks everyone for your continued input and time with this issue. please forgive me for my delayed responses, I've been having to work on other projects so haven't had the required time to really dig into these issues that are being brought up. I should free up within the next 2 weeks...
Thanks LittleInch. Im going to look more into how accurate the Diff PT compared to the Vortex flow meter accuracy, to see if the Diff PT can do the job. I'll post my findings. Probably in 2-4 weeks from now. thanks again.
Thanks everyone. your help/input is much appreciated.
georgeverghese: Sorry, I left the thermocouple information out. The thermocouple is to alarm in the DCS incase the pump's maximum operating temperature is exceeded.
Thanks bimr. Higher accuracy is desired (please correct me, if the diff press transmitter can perform good enough to get the same results):
To reduce inaccurate measurements that can cause the pump to still be repaired from operating below its minimum flow rating.
to avoid future problems/...
Hello,
I was wondering what method is more accurate to measure flow given the below application?
Im helping with a project that involves measuring flow for feedwater (steam cycle power plant). It’s to measure flow at the discharge of a pump and the flow meter will control a valve on the pump...
Thanks everyone for the responses. I appreciate the time taken for all the feedback.
mk3223: you are correct, the existing 1" recirculation pipe is not providing enough flow for the pump to reach its minimum flow requirement.
LittleInch: I attached a sketch for your reference. The...
Hello,
Do you guys know if there are any concerns/issues that I should look into in regard to this:
Increasing the amount of water that's being recirculated back to a LP Feedwater heater?
This is for an existing heater drip pump (HDP). The existing HDP has a 1" recirculation line tapped from...
