Abstract
A catalyst alarm system for resin/catalyst spray applications, the system having a first flow sensor that monitors whether a catalyst from a manifold is flowing for supply to a spay gun or other applicator at a specified minimum rate; a second flow sensor that detects if the catalyst is flowing out of a bypass conduit of the manifold, which indicates the catalyst is not being mixed with the resin; a third flow sensor that detects if the catalyst is flowing out of an over-pressure conduit of the manifold, which indicates that only a partial amount of the required catalyst is being mixed with the resin; and monitoring circuitry for providing alarm and/or control features based on activation combinations of the three flow sensors.
Claims4
A flow monitoring system, comprising:
- a source of pressurized liquid capable of providing a feed flow of the liquid, or a recirculating flow of a liquid, or an overpressure flow of the liquid, or combinations thereof;
- a first flow sensor for receiving the feed flow of the liquid and sensing flow characteristics associated with the feed flow of the liquid;
- a second flow sensor for receiving the recirculating flow of the liquid and sensing recirculating characteristics associated with the recirculating flow of the liquid;
- a third flow sensor for receiving the overpressure flow of the liquid and sensing flow characteristics associated with the overpressure flow of the liquid;
- and
- an electronic circuit including:
- a first alarm that is activated if the first flow sensor detects that the feed flow is below a predetermined minimum flow rate;
- a second alarm that is activated if the second flow sensor detects the recirculating flow;
- and
- a third alarm that is activated if the third flow sensor detects the overpressure flow.
