Abstract

Liquid flow sensors connected to flow indicating and control means for determining the liquid flow condition of a fluid system and controlling said systems liquid movement, responsive to an alarm stage and having visual and automatic advantages providing the necessary level of communications in the application of fluid handling such as oil, gas, water and other forms of energy.

Claims

1. A liquid flow device for determining the liquid flow condition of a fluid system comprising, a sensor body mounted in liquid communication with said system, a signal responsive element mounted on said sensor body producing a first signal means, a signal control circuit connected to first signal means indicating said condition of said fluid system, a adjustable flow control means connected to said signal responsive element to indicate and control said flow condition.

2. A liquid flow device as set forth in claim 1 wherein said liquid flow condition the qualitative measurement from no flow to maximum flow in a fluid system.

3. A liquid flow control as set forth in claim 1 wherein said liquid flow measures the specific flow of liquids and said flow pressure in said sensor body.

4. A liquid flow device as set forth in claim 1 wherein said liquid flow system is connected to said signal responsive element providing a warning and alarm means connected by said signal control circuit to first sensing means and to alarm and warning means.

5. A liquid flow control as set forth in claim 1 having indicating gauges wherein said control is used for the combination of measurement and control of fluid systems in cooperation with said indicating gauges and flow control means.

6. A liquid flow control as set forth in claim 1 having flow, pressure and speed gauges wherein said control works in combination with said flow pressure and speed gauges having visual and electronic means of warning when a malfunction occurs.

7. A liquid flow control device as set forth in claim 6 wherein said control comprises having settable flow control levels for minimum required flow, pressure and speed and warning indicator lights, cooperating with said gauges.

8. A liquid flow control device as set forth in claim 6 wherein said rotatable flow control switch is mounted in combination with one or more of said gauges responsive to measurement and control of liquid flow.
