Capacitive sensor, system, and method for measuring parameters of a two-phase flow |
摘要 |
A capacitive sensor for measuring flow parameters of a two-phase flow, a device for measuring phase concentration of a two-phase flow, and a system and method for measuring flow parameters of a two-phase flow is disclosed. In the capacitive sensor, at least one pair of electrodes is twisted by 180° in a common direction into a spiral shape. Edge guard electrodes are twisted in the common direction and are formed between adjacent electrode edges. Problems of non-homogeneous sensitivity distribution of a measuring field and soft field effect can be effectively addressed, thereby allowing reliable and accurate measurement of phase concentration of a two-phase flow. The system for measuring flow parameters of the two-phase flow can output signals with a current of 4˜20 mA to a PLC system or communicate with an industrial process control computer or with a remote control computer system in a operating room. |
