Description
12、13、16 直管路
14、15 超音波送受波器
Claims (4)
- 流路用管体にそれぞれ取り付けた1対の超音波送受波器により交互に前記流路用管体に超音波パルスを送信し、相手側の前記超音波送受波器からの超音波パルスを受信し、前記流路用管体内を流れる流体を伝播する超音波の伝播時間の変化を基に流量を測定する伝播時間差方式の流量計であって、前記流路用管体は曲管路の両側に2つの直管路を配し、前記2つの直管路に前記超音波送受波器をそれぞれ設置し、一方の前記超音波送受波器から送信した超音波を前記曲管路の少なくとも2個所の管壁で反射させて他方の前記超音波送受波器で受信し、前記2つの超音波送受波器の前記2つの直管路に対する超音波の送受信角度θ1を、前記曲管路における反射角度θ2よりも小さくしたことを特徴とする超音波流量計。
- 前記2つの直管路は軸線同士を同一としたことを特徴とする請求項1に記載の超音波流量計。
- 前記2つの直管路は軸線同士をずらせたことを特徴とする請求項1に記載の超音波流量計。
- 前記曲管路中に他の直管路を挿入したことを特徴とする請求項1〜3の何れか1つの請求項に記載の超音波流量計。
