Questions regarding double-flange level gauges and pressure-transmitting tube level gauges? Double-flange transmitter DP and pressure tube level transmitter DISP

So what does DISP mean, which is indicated next to the level gauge transmitter in the case of a pressure tapping method? Meanwhile, in PID diagrams, for some level gauges, an LT (level transmitter) is shown; the signal is sent to the LC, which then controls the valve. For other level gauges, the pressure tap is connected directly to the LC, which controls the valve. Is it standard to omit the LT in this way of representation?
I want to see how to draw a level gauge; I can’t find it anywhere. Please share the diagram and give me the answer
DISP is short for displacer; it should be a float interface meter used for measuring interfaces!
