Understanding the source of noise in a cistern due to disturbances in level measurement.
When a cistern is noisy, the problem is most likely to arise from disturbances in the level measurement, such as surface turbulence, boiling of the liquid, or agitation. These factors can introduce noise into the system, affecting the overall sound produced by the cistern.
One method to minimize noise in the level measurement is by using a displacer in a stilling well. This technique filters out high-frequency noise caused by turbulence in the tank, although it may lead to bobbing levels due to low-frequency movements within the well.
