Non-contact sensor for control of flow rate - has float position in test section that is detected by non-contact sensors used to control flow valve
An automatic system is used to maintain a constant flow velocity through a flow line. Flow from a supply line (1) to an output line (2) is regulated by a control valve (4) that is regulated by signals from sensing stages (7,8). The flow sensor consists of a float (6) that changes the height in a tap...

| Zusammenfassung: | An automatic system is used to maintain a constant flow velocity through a flow line. Flow from a supply line (1) to an output line (2) is regulated by a control valve (4) that is regulated by signals from sensing stages (7,8). The flow sensor consists of a float (6) that changes the height in a tapered section (3) dependent upon the flow rate. The sensing stages, which can be either optical or magnetic, are set to provide signals that relate to switch on and switch-off conditions for the valve. |
