ABSTRACT:
A mobile fill station for filling propane cylinders by weight and volume. There can be up to three cabinets in the system wherein any one of the cabinets can have a beam scale with a hydraulic automatic stop device to stop filling automatically as the total weight of the cylinder reaches a pre-set scale limit. Any one of the cabinets can also include a flow meter to stop filling when an operator monitors an amount on the meter and manually stops propane flow. The cabinets could also include an electronic scale with a digital indicator where filling stops automatically as the total weight of the cylinder reaches a pre-set computer limit.
