Flow-electrostatic coupled field modeling; simulation and calculation of a capacitive level sensor with lubricant oil tank are carried out
based on a numerical simulation tool. The model describes liquid surface change caused by attitude movement of lubricant oil tank
further cause liquid level change and working capacitance change of sensor. According to computation result
effect of working capacitance change of sensor is significant caused by attitude of lubricant tank and the percentage can reach 15. 86 %. Compared with measured value of the level measurement test platform
the simulation value shows great anastomosis
and the deviation is low. The simulation and modeling based on flow-electro-static coupled field is verified feasible and effective.
