This research aims to develop an innovative array capacitance hydrostatic level measurement,which combines capacitive digital caliper with hydrostatic level measurement,and is expected to substitute for the widely used optical level. The paper illustrates the system of array capacitance hydrostatic level measurement,its mechanical structural design and its design solution of hardware circuit. Compared with the traditional optical level,one of the biggest marks of hydrostatic level measurement is low power consumption with rechargeable batteries and automatically recorded data. It can not only reduce expenditure on labor costs,but also improve the reliability of system. Practice has proven that this project is feasible and has good results.
