Generally, medical equipment has relatively high requirements for liquid level detection accuracy. 

The liquid level detectors on the market are all uneven in liquid level accuracy. But in general, the accuracy of the photoelectric type Water Level Gauge is relatively high, it can be controlled within ±1mm. The accuracy of the float type sensor is relatively poor, about ±5mm.

If the equipment requires a high-precision Water Level Gauge , you can consult EPT. EPT has been focusing on the liquid level detection industry for more than 18 years, so it has a wealth of experience.
