Happy new year, hope all the best for 2018.
On site we have a feed water pump discharging water through HP Economizer to HP Drum, though 30% and 100% control valves. At openings of 30% valve lower that 30%, the flow values is 0. The flow is measured with the use of an orifice and a differential pressure transmitter. The transmitter is OK, it was checked. Can you please suggest any solution?
