Abstract
An active fluid static elimination system installed in a fluid transportation pipeline includes a solenoid valve, an electrostatic measuring device, a fluid destaticizer, and a controller. The solenoid valve is connected to a connecting port of the fluid transportation pipeline, and the electrostatic measuring device is used to measure an electrostatic value of a fluid in the fluid transportation pipeline. The fluid destaticizer is connected to the solenoid valve, and the controller is connected to the electrostatic measuring device and the solenoid valve. The solenoid valve is opened to allow the fluid passing through the fluid destaticizer to eliminate the electrostatic charge of the fluid when the controller determines that the electrostatic value measured by the electrostatic measuring device is greater than a predetermined value.
