Is the accuracy of servo level gauges that are used to measure LPG storage tanks that high? The gas inside the tank is liquefied gas, with the liquid surface being at the gas-liquid interface; can the float gauge achieve a precision of several millimeters?
Thank you for the reply: I would like to add two points: 1. In the case of liquefied gases, a dynamic equilibrium exists on the page; during the phase transition between gas and liquid, is the millimeter-level precision provided by the servo system relevant for measuring the liquid level? 2. Many people pursue precision in order to determine mass. There are many factors that affect the calculation of mass based on liquid level, such as density as you mentioned, as well as errors in the gauge and in the liquid level measurement itself. So what is the actual value of servo level gauges in measuring the liquid level in liquefied gas storage tanks?
I once encountered a servo level gauge whose level accuracy could reach 1 mm, with an interface accuracy of 2 mm. Liquid CO2 has a dielectric constant of around 1.5; radar is not suitable, while servos are a more reliable option.
Because under the same operating conditions, servos are the best choice: they offer high stability, require less maintenance, and provide relatively high precision.
The accuracy of private servers is beyond doubt; this is related to the professional competence of the technicians and the sophistication of the equipment used. According to the principle of buoyant force balance, even with liquefied gas, it is not possible to achieve high precision. However, the price is high and the maintenance costs are also high. As for float level gauges, firstly, such gauges cannot achieve large measurement ranges, and secondly, their accuracy is not on par with that of professional-grade ones.

Compare servos and floats? Hehe, the price difference is over ten times – it’s not very meaningful
