How to calculate the range of the 3051SFA differential pressure volumetric flow meter
Thread Content
The boiler is equipped with two feedwater flow meters of type 3051SFA, connected via DN80 pipes. The pressure at the pump outlet is 2 Mpa. The model of these meters is 3051SFADL030ZCHPS1T100032AA1A2M5; according to the nameplate, their maximum flow rate is 250 T/H and their maximum withstand pressure is 8000 Kpa. In the PLC, the specified range is 0–40 T/H. For the differential pressure measurements, one meter has a setting of 7.5 Kpa while the other has a setting of 8 Kpa. Which of these values is normal? Additionally, how are T/H and Kpa related to each other in terms of calculation?
The maximum range on the nameplate is the highest value that can be used； In fact, those that can be set using HART can be used ； So it is the range of the PLC that is being used ； General technical specifications: Precision – +/- 0.90% for liquids, +/- 1.4% for gases and vapors. Range ratio: 8:1. Flow range ratio. Output: 4-20mA signal, based on Hart? communication or FOUNDATIONTM fieldbus. Sensor material: 316 stainless steel or Hastelloy? C-276. Installation options: Pak-Lok ； Flange connection, with opposite-side bracket ； Flange-Lok ； Threaded Flo-Tap and flanged Flo-Tap (Note: manual and gear-driven are available for both Flo-Tap installation types)
