ELECTRICAL SERVICE WATER METER WIHT A SUBMERGENCE SENSOR}

The present invention relates to an electronic water meter equipped with a immersion sensor. More specifically, the present invention relates to a water meter which is equipped with an inundation detecting device and reports whether the water meter is inundated by determining whether the water meter is inundated.

Conventionally, a water meter is a method of mechanically measuring the flow of water and converting it to a meter scale and displaying it. Such a mechanical meter has to be made by individual meter readers, and to compensate for this, an electronic meter having a means for delivering a meter reading to a manager has been developed.

In the case of an electronic water meter, the problem of excessive manpower operation due to individual meter reading can be solved. However, since the metering manpower is not directly read, the water meter can lose the advantage of regularly checking the situation of the water meter. For this reason, there has been a continuous demand for a system or method for allowing a manager to grasp not only the meter reading of the remote water meter but also the surrounding situation. In the case of the electronic water meter, a plan for remote managers to recognize the flooding situation in real time was required because there is a risk of damage to the device and electric shock due to leakage when the electronic water meter is flooded.

Separately, systems have been developed to determine whether remote locations are flooded.

The Republic of Korea Utility Model Registration Publication No. 20-0179900 discloses a system that can determine the flooding situation of the lower part of the ship in the ship cockpit.

Korean Patent Laid-Open Publication No. 10-2003-0078048 discloses a cargo hold, ballast tank, and cargo hold forward block flooding detection device of a bulk carrier ship. This apparatus discloses a flooding detection device that detects the inflow of water during the flooding of one side wall of the cargo hold formed on the vessel and outputs a flood signal.

In Korean Utility Model Publication No. 97-20018, a sensor is installed to detect flooding of a vehicle due to heavy rain. The sensor signal is inputted from the microcomputer of the vehicle, the car is operated, and then transmitted to a wireless pager of the vehicle owner. A device is disclosed to immediately notify a vehicle owner of a flooded state of a vehicle.

There has been a continuing demand for an electronic water meter equipped with a immersion detection sensor that can identify whether the electronic water meter opened in a remote location and send it to the manager.

It is an object of the present invention to provide an electronic water meter with a submersion sensor.

In one aspect, the present invention is to provide an electronic water meter equipped with a system that can detect the presence of water and report it to a remote administrator.

In another aspect, the present invention relates to an electronic water meter equipped with a system that can detect the external and internal flooding of the water meter, respectively, and report it to a remote administrator.

Other objects and features of the present invention will be clearly understood through the preferred embodiments described below.

Preferably, the sensor of the sensor detection unit is mounted on the bottom of the meter, it can report the inundation situation due to natural or artificial causes.

Preferably, the sensor sensor may detect whether or not the sensor is flooded from one or more sensors. In one aspect of the invention the sensor can be installed on the outside of the meter to detect the flooding of the meter, on the other side of the invention the sensor can be mounted on the inside of the meter, and can be installed inside and outside, respectively have. The sensor detecting unit may detect the inside and the outside of the water by distinguishing and transmitting it to the main processor. When the immersion sensor is installed in the meter, it is preferable to be mounted at the lower end to protect the electric device installed in the meter.

Preferably, the immersion sensor may use a conventional immersion detection sensor. Direct contact and non-contact can be used to determine whether the water is immersed by being directly immersed in water, and the direct contact can be a float, electrode, optical fiber, etc. The non-contact is ultrasonic or air Knowledge can be used

Preferably, the meter according to the present invention may further include a cutoff unit capable of cutting off power when the meter is flooded in addition to the power supply unit. It is also referred to as a power supply / disconnection. The power interruption unit is preferably controlled by the main processor. Preferably the power cut off may operate according to the degree of flooding. In one embodiment of the invention, if the meter ensures a certain level of waterproofness, the external block may not be operated when the intrusion, it may be configured to operate only the internal immersion.
