3、 Structure:
1
The length of the water box and the displacement of the water box can be adjusted by the moving length of the water box and the moving part of the screw plate
The moving length of the water box can be adjusted by the moving length of the water box and the moving part of the screw plate, which can be connected with the moving length of the water box

2
Leveling observation part: a water collimator is installed in the observation cylinder to observe the change of liquid level in the cylinder after being pressurized by the dynamic pressure pipe

3
Reflector part: a reflector is fixed on the mirror shell
The reflector reflects the contact between the water collimation head in the observation cylinder and the liquid level, so that the tip of the leveling head is connected with the shadow tip of its reflection
The reading of the micro voltmeter is adjusted & ldquo; Base point & rdquo;

4
Shell part: the long screw is supported by the shell and cross arm
The shell rod is equipped with leveling bubble and adjusting screw to adjust the verticality of the screw and dynamic pressure pipe of the micro manometer
