3 Overview
The electronic level is composed of a tilt sensor and a digital display and other auxiliary parts, which is a sensor
An angle measuring instrument for measuring the inclination or inclination of the liquid level potential. It has absolute angle measurement, relative angle
Measurement, angle display, angle lock, angle storage and many other functions. The shape of the electronic level is shown in Figure 1.
