Development of a liquid level measurement device based on laser interferometer
Some existing liquid level measurement devices have subjective visual errors during the meas-urement process,which cannot conveniently,quickly,stably,and accurately measure the liquid level height.This article develops a liquid level measurement instrument based on laser interferometry,which can directly obtain the absolute or relative liquid level changes by using the principle of laser interferometry dis-tance measurement.This device has a simple structure,high integration level,and simple operation.The measurement accuracy can reach±0.1 mm,and it has good applicability,economy,and controllability.
