Differential pressure transmitter

Double flange differential pressure level gauge is zeroed after the flange is adjusted to the air and the density and height of the silicone oil are calculated. What is the difference between the two and what impact does it have on the accuracy?
The double flange differential pressure level gauge generally uses the flange you mentioned to zero the air conditioner.； Calculate the density and height of the silicone oil and then perform zero adjustment. The calculation results may be biased due to deviations in the density and height of the silicone oil.
After the double flange transmitter is installed, zero the empty device.
Today, I heard from several masters that calculating the migration amount through the density of silicone oil can make the measurement of the transmitter more accurate. I always thought that the difference is that the up and down movement of the capillary will affect the pressure. How can I calculate it accurately?
