Abstract

A tank monitor control device is disclosed which comprises a monitoring device for insertion into a day tank to monitor a level of fluid stored in the day tank, a shutoff valve connected between a main storage tank and a diaphragm pump, a solenoid valve connected between an air supply and the diaphragm pump, and a control device connected to the monitoring device for receiving a signal indicative of the level of fluid in the day tank, the control device connected to the shutoff valve and the solenoid valve.

Claims

1. A tank monitor control device comprising:

a monitoring device for insertion into a day tank to monitor a level of fluid stored in the day tank;

a shutoff valve connected between a main storage tank and a diaphragm pump;

a solenoid valve connected between an air supply and the diaphragm pump; and

a control device connected to the monitoring device for receiving a signal indicative of the level of fluid in the day tank, the control device connected to the shutoff valve and the solenoid valve.

2. The tank monitor control device of claim 1 wherein the control device comprises a housing having a front face plate.

3. The tank monitor control device of claim 1 wherein control device comprises a housing having a control board having a terminal block for electrically connecting the control device to the shutoff valve and the solenoid valve.

4. The tank monitor control device of claim 1 wherein the control device comprises a housing having a front face plate having an on off toggle switch, a manual fill push button, a test push button, an overflow indicator, a pump indicator, a level within range indicator, a power indicator, and an audible alarm.

5. The tank monitor control device of claim 1 wherein the monitoring device comprises a tube and three reed switches disposed along the tube.

6. The tank monitor control device of claim 5 wherein the first reed switch detects a low level of fluid in the day tank, the second reed switch detects a high level of fluid in the day tank, and the third reed switch detects an overflow level in the day tank.

7. The tank monitor control device of claim 1 wherein the control device provides power to the solenoid valve.

20. The tank monitor control device of claim 1 wherein the control device provides power to the solenoid valve.

8. A tank monitor control device comprising:

a monitoring device for insertion into a day tank to monitor a level of fluid stored in the day tank;

a shutoff valve connected between a main storage tank and a diaphragm pump;

a solenoid valve connected between an air supply and the diaphragm pump; and

a control device positioned at a location remote from the monitoring device, the control device electrically connected to the monitoring device for receiving a signal indicative of the level of waste oil in the day tank, the control device connected to the shutoff valve and the solenoid valve.

9. The tank monitor control device of claim 8 wherein the control device comprises a housing having a front face plate.

10. The tank monitor control device of claim 8 wherein control device comprises a housing having a control board having a terminal block for electrically connecting the control device to the shutoff valve and the solenoid valve.

11. The tank monitor control device of claim 8 wherein the control device comprises a housing having a front face plate having an on off toggle switch, a manual fill push button, a test push button, an overflow indicator, a pump indicator, a level within range indicator, a power indicator, and an audible alarm.

12. The tank monitor control device of claim 8 wherein the monitoring device comprises a tube and three reed switches disposed along the tube.

13. The tank monitor control device of claim 12 wherein the first reed switch detects a low level of fluid in the day tank, the second reed switch detects a high level of fluid in the day tank, and the third reed switch detects an overflow level in the day tank.

14. The tank monitor control device of claim 8 wherein the control device provides power to the solenoid valve.

15. A tank monitor control device comprising:

a monitoring device for insertion into a day tank to monitor a low level of waste oil stored in the day tank to produce a low level signal, a high level of fluid stored in the day tank to produce a high level signal, and an overflow level of fluid stored in the day tank to produce an overflow level signal;

a shutoff valve connected between a main storage tank and a diaphragm pump;

a solenoid valve connected between an air supply and the diaphragm pump; and

a control device connected to the monitoring device for receiving the low level signal, the high level signal, and the overflow level signal, the control device connected to the shutoff valve and the solenoid valve.

16. The tank monitor control device of claim 15 wherein the control device comprises a housing having a front face plate.

17. The tank monitor control device of claim 15 wherein control device comprises a housing having a control board having a terminal block for electrically connecting the control device to the shutoff valve and the solenoid valve.

18. The tank monitor control device of claim 15 wherein the control device comprises a housing having a front face plate having an on off toggle switch, a manual fill push button, a test push button, an overflow indicator, a pump indicator, a level within range indicator, a power indicator, and an audible alarm.

19. The tank monitor control device of claim 15 wherein the monitoring device comprises a tube and three reed switches disposed along the tube.
