I have newly installed a magnetostrictive level gauge on site to measure the liquid level in the tower bottom; however, the feed inlet for the tower bottom is located between the upper and lower flanges of the level gauge. The liquid level fluctuates greatly during current use. PS: The tower is of the pipe-type design, and the space at the bottom of the tower is very limited. Could the cause of these fluctuations be related to the feed position, or perhaps the reboiler volume is too small? The tower circulation inlet is located in the middle of the bottom of the tower, and excessive reboiler circulation may be causing the actual liquid level to fluctuate
To rule out fluctuations in the actual liquid level, it is first necessary to determine the capacity of the tower bottom, as well as the flow rates of inlet and outlet materials. If the capacity is low while the flow rates are high, the liquid level will definitely fluctuate
Does the level gauge have two flange ports? The interference caused by the probe rod should be considered first
With a storage tank of such small capacity and a circulation system, it’s very difficult to obtain accurate readings. There is a strict requirement for the installation of a level gauge: the liquid level must remain stable without any fluctuations, and it’s hard to meet this requirement in your case; it will be challenging to use any type of level gauge.
