As shown in the figure, the double-flange transmitter is used to measure the liquid level, with the transmitter installed on the upper side of the negative pressure side.

The transmitter is installed above the negative pressure side; method for determining the range. (Easy-to-understand version: P)
Liquid level percentage = (Measured pressure difference – 0.93*g*4.7) / (1 – 0.93) / 4.7 * 100%
The range remains the same as ρgh; it mainly depends on migration
The installation position of the double-flange level gauge and the display head doesn’t matter much; the range is only related to the center distance between the two flanges.
The transmitter can be installed in this way; just ensure proper negative migration is achieved
The actual measurement range remains unchanged; after installation is complete, the zero point is adjusted for an empty tank. If you are not confident, you can calibrate it by filling it with water.
The measurement range of a double-flange level gauge has nothing to do with the installation position of the gauge; it depends solely on the center distance between the two flanges. The measurement range remains unchanged, regardless of where the gauge is installed.
The range has nothing to do with the installation location; it’s just that the final range shift is different. Range migration varies depending on on-site conditions, and there is no universal formula for it
It can be determined from the calculation formula that, regardless of where the double-flange level transmitter is installed, its range and zero-point shift do not change as a result of the transmitter’s installation location. In actual installation, to ensure the transmitter lasts longer, it is recommended to install the transmitter below the upper and lower flange openings.
There is no need to consider how to calculate for double flanges. Just charge at them! Just place the table header in a location where it can be easily observed and maintained!
