Who invented water level indicator

Another disadvantage is that the accurate water level is not ascertainable. Yet another disadvantage is that construction of the conventional device is very complicated and the maintenance thereof is very costly and difficult. Still another disadvantage is that the conventional device is not operable by a single person.

Objects of the Invention - Therefore the main object of the present invention is to provide a novel water level indicator which obviates the disadvantages associated with the prior art. The following description contains many specifics, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof.

Many other variations are possible. Accordingly, the scope of the invention should not be limited to the emodiment illustrated, and the alterations and variations may be treated within the spirit and scope of this invention. Summary of the Invention A water level indicator comprising a sensor adapted to be connected one of its end to a cable wound on a rotatable wheel mounted on a stand, the other end of said cable connected to an audio and video signal means provided for indicating water level, said signal means being connected to the power supply means, a handle being provided with said wheel for facilitating winding and unwinding of said cable thereon.

In accordance with this invention of underground water level indicator comprises a sensor connected one of its end to a cable which is wound on a rotatable wheel fixed on a stand. The other end of said cable is connected to a circuit having means for audio and video signals for indicating water level.

These said signal means being connected to power supply means fixed on said wheel. Handle being provided to facilitate winding and unwinding the wheel, which Is connected to the stand through a central axis using bearings. Brief Description of Accompanying Drawings An underground water level indicator to a preferred embodiment is herein described and illustrated in the accompanying drawing wherein; Fig 1 shows isometric view of the underground water level indicator.

Fig 2 shows the sectional view of the sensor and Fig 3 shows the preferred embodiment of the arrangement of audiovisual circuit. Referring to the drawing, Fig 1, a water level indicator comprises a sensor 1 adapted to be connected one of its end to a calibrated cable 2 wound on a rotatable wheel 3 mounted on a stand 4 having means for audio 5 and video 6 signals being provided for indicating water level. The audio video means are preferably a buzzer and LED and which is being connected to the power supply through a switch 8 Handle 7 is being provided to wind and unwind the cable 2.

The best sensor to use in a water level indicator is stainless steel probe sensors. Stainless steel sensors prevent rusting, fouling, and deteriorating due to poor water quality. For example, we only use stainless steel sensors in all of our water level sensors. Water level indicators are important for many different industries.

For example, cooling towers use water level indicators to monitor water levels in a tank and make corrective actions based on the level of water.

Without water level indicators in a water tank, you would have to manually check whether enough water is in the tank, and should your tank ever go empty, it could mean your chiller overheating. Water level indicators allow you to remotely monitor water levels and make corrective actions automatically so you can focus on more important issues. Water level indicators are usually sold as a 2-part system, the control panel, and water level indicator probe sensors.

Some water level indicator systems allow up to 6 sensing probes, while others only allow 2 depending on the configuration you need. Read more about water level indicator systems.
