Conventional deck runoff, because conventional deck runoff differs smaller compared with the dielectric constant of rainwater, then the first detection means and
The rainwater of two detection means measures and conventional deck runoff dielectric constant irrelevance also very little, the irrelevance numerical value of detection without departing from
Normative reference deck runoff dustiness deviates table.(2) if accident deck runoff：First collection device and the second collection device are received
Collection is rainwater and accident deck runoff, because accident deck runoff differs larger compared with the dielectric constant of rainwater, then first

Sensor, certainly described capacitance sensor also includes circuit board 7 and circuit board housing 8, and this will not be repeated here for prior art.
Further, insulation dielectric has been acted as when the detected fluid pours into gap 4, now capacitance sensor and Qi Nei's is tested
Fluid just forms an electric capacity, different according to the dielectric constant of fluid in cavity, the electric capacity between two electrodes detected
Can be different.Similarly, we can also draw the dielectric constant of tested fluid measured according to the capacitance detected.
In the present embodiment, the interior electrode 2 is cylinder, and external electrode 3 is cylinder barrel shaped；The interior electrode 2 is concentric
It is nested in inside external electrode 3, it is opened with the fixing end of the fastener 1 closing other end.So it is provided with uniform beneficial to detected fluid
