At the level gauge, a “pipeline” weight is reduced from the sensor unit, which is fixed at the top of the tank, as long as the weight is in contact with the material surface. The weight is then added to the sensor unit and the line is measured. The resulting measurement is then used to calculate the level of material in the tank.
Surface Detector Level Gauges
Unlike servo floating gauges, which have continuous measurements, surface detectors are periodic measurement systems.
The most common problem reported with surface detector level measurement systems is that the weight of the piping can break down per sensor unit. Similar to floating wire conduction systems, the components of this method are prone to acceleration wear due to the continuous movement of the float on the liquid surface, which causes continuous movement on the mechanical components. Therefore, the reliability level of this method is potentially weak. It has been suggested by industry experts that both system designers and manufacturers consider this method for measuring the tank, which should no longer be used due to the variable level of reliability and measurement accuracy, as well as the methods required for high maintenance. .
