Study on Measuring Model of Glass Tube Variable Area Rotameter Based on Inductance Sensor
摘要
Abstract
To achieve the signal distant transfer of glass tube variable area rotameter, inductance coil was designed by iron core embedded in the glass Cone tube and enameled wire on the outside of the glass tube. Then experimental studies on inductance sensor was made by bell gas flow standard installation. The approximate linear relation between calibration of floater and inductance value was obtained and the functional relation between inductance value and gas flow rate was presented. Finally,the model of measuring gas flow rate based on inductance sensor was verified,the results showed that the measuring accuracy was within 2. 5% .关键词
