The weight filler is first connected to the supply source (hopper), after connecting, the user can open a valve to allow the product to flow towards the weight filler. 

The user will select the desired filling weight from the indicator and place an empty bottle on the load cell. Using the bottle guide to ensure the bottle opening is seated below the filling nozzle and the sensor will detect if there is a bottle or not. In the absence of a bottle, the filling process is unable to start.

The indicator will automatically zero the bottle weight prior to any filling, achieving the desired net weight of the product after the filling is done.

Filling is done in 2 stages; 1st stage at high speed and the 2nd stage at a slower speed to ensure accuracy. The filling nozzle will shut close after filling to prevent dripping. Once completed, simply remove the filled bottle and put an empty one in.
