Calculate LRV and URV for a differential pressure transmitter | Liquid Level Measurement

[@cyberlads28]

Cool stuff

[@jamesowusu-ansah595]

Thanks for the video...but i would want to ask, since we won't be able to set a negative value into the differential pressure transmitter, in both solutions, we had the LRV to be negative and HRV to be positive. Do we neglect the negative sign on the LRV and input both LRV and HRV as positive values

[@InstrumentCalibration]

Yes...you need to apply positive values to both sides. In this example, negative pressure value indicates that lower side has higher pressure as compare to high side of DP Transmitter. Hope you get your answer.

Thanks for video. I have a question. The span is 168 inches.(16.8-(-151.2). Does it mean that I must insert to transmitter LRV 15.8, URV168 inches?

[@InstrumentCalibration]

I did not get your question. Could you please explain me in detail?

[@elcinaliyev2321]

@@InstrumentCalibration . LRV=-151.2 inch, URV=25.8inch.
1) İs span equal to 177 inch?
2) Which value for LRV and URV we must insert to transmitter?

What is 12 inches stand for ?

[@InstrumentCalibration]

Thanks for asking this question. 1 feet is equal to 12 inches.

why is LG =0.9 on low side pressure?

[@InstrumentCalibration]

Impulse line's fluids specific gravity is 0.9.

@Mdirshad Thanks for your valuable comment

hydrostatic pressure = density x gravity x Height......why did we ignore Gravity= 9.8
