Description
本発明は、上記従来の問題点に鑑み、流量計測に超音波センサを用いてガス圧力が脈動している状態を検出できるガス保安装置を提供することを目的としている。
2 ガス流路
3 超音波センサ駆動回路
4 制御回路
5 時間計測手段
6 脈動記憶手段
Claims (1)
- ガスが流れるとともに遮断手段が配設されたガス流路と、ガス流路の対極する位置に配設され超音波の発信部と受信部からなる超音波センサと、超音波センサを駆動する超音波センサ駆動回路と、超音波センサ駆動回路及び遮断手段を制御する制御回路とを備え、
前記制御回路は、下流から上流方向に超音波が進む場合の送信から受信までの時間差t1から上流から下流方向に超音波が進む場合の送信から受信までの時間差t2を引いた結果が負の値と正の値を含む場合にガスの脈動が発生していると認識する手段と、前記負の値と正の値が交互に出力されるときの前記負の値と正の値の1回の出力を1周期として何周期出力されたかを記憶する脈動記憶手段を有し、
前記脈動記憶手段によりガス脈動の発生情報を検知するようにしたガス保安装置。
