The present invention relates to a pneumatic tamponage device for a water level meter, and more particularly, to a method for calibrating a water level measuring instrument, in which air supplied from an existing air pipe is supplied to an impregnation tank, And the water level is easily grasped by performing the function of appending and correcting, thereby improving workability and efficiency.

In general, the pressure and flow measurement of the process control system are performed by measuring the physical quantity by contacting the media of the system with the measuring instrument through a pipe tube or tube.

Normally, the concept of pressure is defined as the "force acting per unit area" defined by Pascal's law. The pressure sensor of the actual instrument adds the force of the water head corresponding to the pressure of the process system and the reference height of the pressure tube, It is detected by the amount of pressure.

For example, in a conventional pressure level meter, the wet leg type indicates the water level using the pressure difference between the low pressure side pressure reference and the high pressure side pressure gauge. In this calibration method, high pressure side high pressure side pressure pipes corresponding to high and low pressure values are generated to generate differential pressure with the low pressure side pressure pipe, and the output (output) of the level transmitter is converted into a tester After confirming, it is calibrated by the loader.
