Mass flow rate detector of electrostatic type |
摘要 |
A flow rate detector of the type comprising a corona discharge circuit to cause partial ionization of a fluid at a section of a fluid passage and a probe positioned downstream for detecting the amount of ions carried by the fluid as an indication of the fluid flow velocity. To achieve direct detection of mass flow rate even when the fluid exhibits fluctuation in its density, the detector includes a control circuit which serves the function of maintaining the intensity of a discharge current flowing through the corona discharge circuit constant.
