| description | PROBLEM TO BE SOLVED: To provide a gas shut-off device capable of effectively avoiding a risk of erroneously determining that a change in gas types is generation of condensation.SOLUTION: A gas shut-off device includes: amplification means 7 for adjusting an amplification degree of a reception signal and amplifying the reception signal so that a received ultrasonic signal has amplitude within a prescribed range at ultrasonic transceivers 2 and 3 set as a reception side; propagation time measuring means 11 for measuring a propagation time of an ultrasonic wave; flow rate computation means 12 for computing a gas flow rate from the propagation time; and condensation determination means 13 for determining condensation is occurring in a measuring channel 1 if the amplification degree adjusted by the amplification means 7 changes exceeding a determination value set according to the propagation time.SELECTED DRAWING: Figure 1
【課題】 ガス種の変更を結露の発生と誤判定するおそれを有効に回避することができるガス遮断装置を提供する。【解決手段】 ガス遮断装置は、受信側に設定された超音波送受信器２，３において、受信した超音波信号が所定範囲の振幅になるように、受信信号の増幅度を調整して増幅する増幅手段７と、超音波の伝搬時間を計測する伝搬時間計測手段１１と、伝搬時間からガス流量を算出する流量演算手段１２と、増幅手段７で調整された増幅度が、伝搬時間に応じて設定される判定値を超えて変化した場合に、計測流路１内に結露が発生していると判定する、結露判定手段１３と、を備えている。【選択図】 図１ |
