Rather than using pictures to explain this, monkeys, pick up the silver coins and throw them – aim well and toss them into Kuryo’s arms. {:2_40:} {:2_32:} {:2_37:} {:2_36:} {:2_42:} {:2_45:}

In the gas collection and pressure measurement cylinder, the liquid pressure is converted into an equivalent air pressure, which is then transmitted to the \"lossless pressure transfer diaphragm sealant.\" This sealant in turn transmits the pressure to the sensor diaphragm, and ultimately to the sensor chip. Finally, the pressure of the liquid column is converted into a liquid level value, which is displayed and outputted.......

Gases are compressible; they transmit pressure, resulting in large errors. It’s okay if the precision requirement isn’t high.

The brothers who posted replies above – why doesn’t the system automatically reward them with wealth? . I have set it up. @Cleaner

Conclusions with low accuracy are wrong. Inside the gas collection and pressure measurement tube, there is a zero level for measurement – the liquid-gas equilibrium level; its fluctuation is of about ±2 centimeters... Compared to the typical ranges of 5 meters or 10 meters used in industrial applications, is an uncertainty of 2 centimeters considered large? 2 cm ÷ 5 meters = 0.4% FS; 2 cm ÷ 10 meters = 0.2% FS. Additionally, this ±2 cm uncertainty is related to various factors such as stirring, scaling, boiling, bubbling, changes in the temperature of the liquid, and changes in liquid column pressure, across all operating conditions. For industrial measurement, a level gauge that can operate continuously for a year or even several years without maintenance and without giving false readings under harsh conditions is truly excellent – it’s almost like a miracle device. Especially since it is relatively inexpensive and comes without any additional operating costs. By holding its breath over time, it achieves ideal isolation at low cost; it enhances the performance and credibility of static pressure level gauges, and it significantly broadens the range of applications for such gauges. So I must sing a hymn in its honor....... {:2_42:}

Is the air inside compressed by the medium being tested? Then fed back to the gauge head?

So, is its principle still the pressure formula ρgh?
