Description

Technical field: [0001] The invention belongs to the field of liquid level measurement, and relates to an input pressure liquid level gauge, in particular to a self-calibrating high-precision input pressure liquid level gauge. Background technique: [0002] The principle of the drop-in pressure liquid level gauge is to put the pressure sensing element directly into the liquid and place it at the bottom of the liquid, and divide the measured liquid pressure value by the density of the liquid and the acceleration of gravity to calculate the liquid level height. That is, the liquid level height h=P / (ρg), wherein, P is the measured pressure, ρ is the density of the liquid, and g is the acceleration of gravity. The submersible pressure level gauge is extremely low in cost because of its very simple structure. The unit price of other various liquid level gauges is about 5,000 to 50,000 yuan. The cost of the input pressure level gauge is only a few hundred yuan. However, since i...
