Description

Wireless electronic water meter calibration device

Technical Field

The utility model mainly relates to a water gauge technical field especially relates to a wireless electronic type water gauge school table device.

Background

Water meters, as a kind of measuring device, are commonly used in daily life, and can be divided into mechanical water meters, mechanical water meters with electronic devices and electronic water meters, and the current market demand is gradually replaced by electronic intelligent water meters. The traditional meter calibration mode of the water meter is single meter calibration, and the error coefficient correction of the electronic water meter is gradually developed from the adjustment of a single meter mechanical flow regulating valve of a mechanical meter, but the single meter is generally used for error calibration. The current mechanical water meter and the electronic water meter with the electronic device have certain intelligent functions, but the general meter calibration mode is performed through handheld equipment or a wired device is used for butt joint communication meter calibration. The handheld equipment generally corrects errors one by one, a wired device is adopted to correct the meter one by one, meanwhile, a wire harness is dragged, the work on a meter correcting station is troublesome, the production efficiency is low, and misoperation and repeated operation are easy to occur, so that the meter is corrected repeatedly.

In summary, the conventional meter calibrating device has the following defects:

wired communication, and connection from internal wiring, or reservation of internal socket,

and then the external communication lines are butted. The sealing protection performance of the water meter is easily damaged, so that the water meter is protected to cause a water leakage hidden trouble;

secondly, when the meter is calibrated in a wired mode, the efficiency of a single meter is low, the operation is complex, wire harnesses are messy in the multi-meter application process, the wiring is complex, the efficiency is low, each meter cannot be operated by adopting a command in broadcasting, the water meter address is set in the meter calibrating process every time, the multi-meter can be operated simultaneously, and once the address is omitted at a certain time, the meter calibrating is greatly influenced. Or because the error cannot be corrected due to the fact that the individual water meter is calibrated, the error is within the maximum allowable error range, at this time, the address needs to be changed, the table with the address needs to cancel the operations such as address and the like again, and a series of operations performed before can be wasted.

Secondly, the meter is calibrated by adopting movable equipment, such as a palm machine, and general errors need to be corrected manually

Input and even manual calculation are low in efficiency, and misoperation is easy to occur.

And fourthly, in the process of meter calibration, the meter calibrator needs to continuously operate the water meter and the meter calibration equipment, so that the work is more than half, and the efficiency is general.
