Gas safety meter with multifunction indication device

摘要

The present invention determines the current state of the gas facility by the microcontrol unit through a signal input from the sensors of the plurality of input means and a signal controlled by an external user, and operates the solenoid valve according to the result to operate the gas. The present invention relates to a gas safety meter having a multi-function display device which supplies or cuts off and displays the operation information or abnormal state of the gas facility differently through letters and numbers.;The constitution of the present invention comprises: input means for inputting a signal sensed by operation of a sensor or switch such as pressure, flow rate, vibration, carbon monoxide, gas detection, container exchange, test input, gas open input, and the like; External connection means for connecting with the external input / output means; Control means for determining an operating state of a gas facility by a signal input from the input means and an external connection means, and outputting a control signal according thereto; Drive means for supplying and blocking gas by operating a solenoid valve in response to a signal output from the control means; Characterized by the signal output from the control means characterized in that it comprises a display unit for displaying the current state of the gas facility through the letters and numbers differently the risk information.
