DOWNSTREAM PROPAGATIONとは 意味・読み方・使い方

To solve a problem in finding the propagation time of an ultrasonic wave that a difference arises between a waveform received on the upstream side and one on the downstream side in a portion where a received amplitude is comparatively large and that the difference is to be detected as an error in propagation time.例文帳に追加

超音波の伝搬時間を求める際、比較的受信振幅の大きい部分では、上流側と下流側とで受信する波形に差が発生し、伝播時間の誤差として検知されることになる。 - 特許庁

To solve the problem, wherein a difference arises in a received waveform between the upstream side and the downstream side, in a portion where a reception amplitude is relatively large and the difference is detected as error in the propagation time of ultrasonic waves, at the determination of the propagation time.例文帳に追加

To solve the problem wherein when determining propagation time of ultrasonic waves, a difference is generated between the reception waveforms on the upstream side and the downstream side, in a part where reception amplitude is relatively large and detected as an error of the propagation time, so that it is difficult to achieve flow measurement with high accuracy.例文帳に追加

Ultrasonic waves are transmitted from an upstream ultrasonic converter 3 and from a downstream ultrasonic converter 4 substantially at the same time, and received by the downstream and upstream ultrasonic converters, respectively, and the ultrasonic propagation time is determined from the time difference between the both.例文帳に追加

上流側の超音波変換器３と下流側の超音波変換器４とから超音波をほぼ同時に送信し、それぞれ下流側と上流側の超音波変換器で受信し、その時間差から、超音波伝搬時間を判定する。 - 特許庁

Because this time t0 is not affected by a temperature of a fluid, propagation time of an ultrasonic beam from upstream to downstream is calculated based on the time t0 and so is the same from downstream to upstream, and then the flow rate is calculated.例文帳に追加

この時間ｔ０は流体の温度に影響されない時間であるから、この時間ｔ０を基に超音波ビームの上流から下流、下流から上流への伝播時間を求め、流量を算出する。 - 特許庁

A propagation time difference between a forwarding time of the ultrasonic wave beam B from an upstream side to a downstream side and a returning time of the ultrasonic wave beam B from the downstream side to the upstream side is calculated to obtain the flow rate.例文帳に追加

超音波ビームＢが上流側から下流側への往き時間と、下流側から上流側への戻り時間との伝播時間差を求めて流速を求める。 - 特許庁

Ultrasonic transmitter-receivers 8, 9 located upstream and downstream of a measuring passage 6 where a measured fluid flows, are arranged in open holes 11, 12, and a propagation path flow regulating body 43 having a regulating part 44 exposed into the flow is provided along the ultrasonic propagation path 13 between the upstream and downstream ultrasonic transmitter-receivers 8, 9.例文帳に追加

被測定流体が流れる計測流路６の上流側および下流側に位置する超音波送受信器８，９を開口穴１１，１２に配置し、さらに、これら上、下流側の超音波送受信器８，９間の超音波伝搬路１３に沿うとともに、流れの中に露出する規制部４４を有する伝搬路流れ規制体４３を設けたものである。 - 特許庁

Based on the measurement of the propagation time, whether the substitution liquid is delivered upstream (predilution) or downstream (postdilution) of the dialyzer is confirmed.例文帳に追加
