The liquid level sensor sensitivity refers to the ratio of the output quantity change Δy to the input quantity change Δx of the liquid level sensor under steady state operation. It is the slope of the output-input characteristic curve. Sensitivity S is a constant if there is a linear relationship between the output of the level sensor and the input. Otherwise, it will change as the amount of input changes. The dimension of sensitivity is the ratio of the dimensions of the output and the input. For example, for a displacement level sensor, when the displacement changes by 1 mm and the output voltage changes to 200 mV, the sensitivity should be expressed as 200 mV/mm. When the output of the liquid level sensor and the dimension of the input amount are the same, the sensitivity can be understood as a magnification. Increased sensitivity for higher measurement accuracy. However, the higher the sensitivity, the narrower the measurement range and the worse the stability.

The resolution of the level sensor is the ability of the level sensor to sense the measured small changes. That is, if the input varies slowly from some non-zero value. When the input change value does not exceed a certain value, the output of the liquid level sensor does not change, that is, the change of the input level of the liquid level sensor is not distinguishable. The output will only change when the input changes more than the resolution. Usually, the resolution of the liquid level sensor at each point in the full-scale range is not the same. Therefore, the large change value in the input amount that can make a step change in the output in the full-scale range is used as an index for measuring the resolution.
