Do you know How D.P. transmitter can be applied to close tank?

Answers:

In closed tank, bottom of the tank is connected to the high pressure side of the transmitter. Top of tank is connected to the lower pressure side of the transmitter. In this way vessel pressure can be measured.

yes your answer is right but the important point is you should know how to install .If u connect bottom side to (+) side & top side to(-) it never works . The transmitter installed parallal to HP tapping or below the HP tapping then calibrate it.

In a closed container carry equal pressure I'n any poles.. High port connect to tha tank. Low port connect to atmosphere.....

here Pascal will be applicable...........the pressure will be same every where in tank
