Regarding differential pressure flow meters, the range design of spinal canal flow meters
Thread Content
A new differential pressure transmitter has been installed on site to measure the flow rate of heavy oil; the specified range per the design specifications is 0–100 kp. It’s a Yokogawa EJA differential pressure transmitter. Now that the flow calculation sheet has been provided, the corresponding range there is 0.02–4 KP, while the DCS system uses a range of 0–1000 M3/H. So, should we use the range specified in the design documents or the range indicated in the calculation sheet? I’m a bit confused
All relevant information should be included in the calculation sheet – differential pressure, flow rate, and so on; so of course, the information from the calculation sheet should be used
According to the calculation sheet, the specification sheet is not acceptable.
May I ask, does the flow square root calculation start by taking the differential pressure from the calculation sheet and then taking its square root?

If the range in m3/h specified in the flow calculation sheet does not match the range in the DCS, the DCS range should be set according to the m3/h value given in the flow calculation sheet, while the differential pressure transmitter should have its range set based on the kPa value specified in the flow calculation sheet. If the transmitter applies squaring, the DCS does not. If the transmitter does not perform squaring, the DCS must do it
