Device for Measuring Two-phase Flow Phase Concentration, System and Method for Measuring Flow Parameters of Two-phase Flow

摘要

invention is two-phase flow of the flow parameter sensor for detecting a capacitor, two-phase flow the concentration detecting device, 2 relates to the flow upstream of the detection system and method perm liter. In the capacitive sensor forms a spiral at least one pair of electrodes is twisted 180 in accordance with the same manner, between the adjacent edges of the electrode in the same manner as the twisted edges of the strip-like protective electrode is formed. By the above structure, when the detection resolution of the sensitivity distribution is most uniform and soft to not issue the developer (soft field effect), and the problem effectively, reliably and it is possible to detect the concentration of the two-phase flow accurately. The two-phase flow of the flow parameter detection system outputs an analog signal with a current of 4 ~ 20mA to the PLC system, or via the RS485 bus CANBUS or an industrial process control computer and the communication of the electrical room, or the central control room via the TCP / IP protocol, The progress of the remote control of computer systems and communications.
