    Patent number: 5836201
    Abstract: A solvent recovery dryer having a flow sensing device in communication with the output of the solvent recovery dryer. The flow sensing device is in operable communication with a computer and the computer calculates the flow rate of liquid being recovered, and controls the dryer when a certain flow rate is reached. The computer also stores and displays flow rate data. The flow sensing device provides for nearly continuous monitoring of the flow rate, and also provides for accurate monitoring of flow rates at high and low levels of liquid flow.
