Dual-flange differential pressure level transmitter
Thread Content
For a double-flange differential pressure level transmitter, how is the center distance between the two flanges determined? Is it determined based on the lowest and highest liquid levels?
Customized, based on the measurement range required by the process
The flange center distance should be measured by yourself if no drawings are available; the low and high liquid levels required by the process specifications necessitate calculation for adjustment.
The range is equal to the distance between the centers of the two flanges

Generally speaking, the center distance between the two flanges corresponds to the liquid level range of the level gauge, but other possibilities also exist. In fact, the position of the upper and lower flanges determines the range that can be measured by a double-flange level gauge – the upper limit is set by the upper flange and the lower limit by the lower flange. Thus, the distance between the centers of the flanges represents the measurable range; this range is related to the scale range, but it is not necessarily identical to it. The flange spacing is determined based on the lowest and highest liquid levels; the spacing between the upper and lower flanges must be sufficient to accommodate them, otherwise measurement will not be possible.
