Explosionproof mobile filling system

For the main part the mobile filling system consists of an intrinsically safe flow meter, an electro-pneumatic valve and an intrinsically safe batch controller that is built into the controls

(Ex eb db mb ia [ib] IIC T4 Gb). The piping of the Coriolis flow meter for mobile applications is made of 1.4435 stainless steel. When used in the automatic mode, the filling process stops before the quantity that is preset at the batch controller is reached and the valve closes automatically. In the manual mode the batch controller only acts as an indicator displaying the momentary flow rate. With this process the inlet valve is operated manu-ally. Further manual valves are used for emptying the pipeline.
In order to exclude an electrostatic charge when connecting pipes or hoses and filling vessels, the spiral cable for the equipotential bonding must remain connected until the operation has been fully completed.
