Video Content:
Example: A flow measurement system comprising of an orifice plate has an input of 0 to 100 Inches WC representing a flow of 1 to 200 L/S. What differential pressure is required to increase the flow range to 0 to 300 L/S?
Square Root of Revised DP= (Revised Flow)/(Existing Flow) *Square Root Of Existing DP
Square Root of Revised DP = 300/200 *√100
Square Root of Revised DP = 1.5 * 10
√(Revised DP) = 15
Revised DP = 〖15〗^2
Revised DP(URV) = 225 Inches WC
Square Root of Revised DP= (Revised Flow)/(Existing Flow) *Square Root Of Existing DP
Square Root of Revised DP = 0/1 *√0
Revised DP(LRV) = 0 Inches WC
For Flow Range: 0 L/S TO 300 L/S= Differential Pressure Range: LRV = 0 Inches WC
URV =225 Inches WC

👍👍👍 nicely explained

[@InstrumentCalibration]

Thanks

[@higomariya2991]

Thanks please more videos like this on delta p

[@InstrumentCalibration]

Our team would work on the same.
Thanks for the suggestions

[@nelsonpantaleon7751]

Sir i liked your video so much and i always wstching your videos sir. When you create a video or course about this calculation of dp transmitter how to use this calculation in the real world plc programming

[@InstrumentCalibration]

Hello Nelson
I am still working on this course. Please give me some time. I will share with you once it is ready.

[@nelsonpantaleon7751]

@@InstrumentCalibration ok sir thank you i will wait sir 🙏i hope thats TIA PORTAL because im a TIA PORTAL user thank you sir

[@user-xz7nt4si3s]

Hi. Thanks a lot for the existing calculation. how much i change the DP and mass flow for DP type FT if the existing one is 0-2500 mm h20 and 6000 kg/hr. Can i change this DP upto 0-15725 mm H20 and 15000 kg/Hr?

I wired todaY my first model 230 barometric senser got abit confused as to what the units purpus was .like was it a voltage unit or a current unit at first me thinking 3 wire but no 2 wire instead sendi g the current 1 direction

I have a flowmeter with range of DP of 0-48.6” , I would like to know the maximum flow that it can read. Can you please advise?

[@user-tx8ek1hp5r]

Hi I want to re range the transmitter from 200 l/sec to 300 l/sec what should I do

[@UcoK0007]

Thanks a lot Mr.
Mr., How to know flow range a DP transmitter on name plate DP range is 0 to 2500 mmH2O, then data engineering they have for flow range is 0 to 243 m3/h.
I just want to know how to make that flow range to be like that, i.e 0 to 243 m3/h?
Thank you

[@InstrumentCalibration]

Hello muhammad
It all depends on your process. In this example, system creates differential pressure of 2500 mm H2O at 243 m3/h flow rate.
