超音波流量計は、超音波が流体内の 2 点間を伝わるのにかかる時間を測定する原理に基づいて動作します。超音波流量計には、通過時間型とドップラー型の 2 つの主なタイプがあります。通過時間流量計は、超音波がパイプ内を上流と下流に伝わるのにかかる時間を測定します。一方、ドップラー流量計は、流体内の粒子や気泡から反射された超音波の周波数シフトを測定します。
重要な要素の 1 つ超音波流量計の利点は、その非侵入性です。パイプへの切断やプローブの挿入が必要な従来の流量計とは異なり、超音波流量計は外部に設置できるため、漏れや汚染のリスクが軽減されます。このため、流体の完全性を維持することが重要な用途に最適です。
超音波流量計のもう 1 つの利点は、広範囲の流量と流体の種類を測定できることです。浄水中の低流量を測定する場合でも、腐食性化学物質中の高流量を測定する場合でも、超音波流量計は正確で信頼性の高い測定を提供します。さらに、超音波流量計は温度、圧力、粘度の変化の影響を受けないため、多用途でさまざまな動作条件に適応できます。
精度の点では、超音波流量計は高精度であることで知られています。技術の進歩により、最新の超音波流量計は測定値の最大 0.5 パーセントの精度を達成できます。このレベルの精度は、プロセス制御と最適化のために正確な流量測定を必要とする業界にとって不可欠です。
超音波流量計を選択する場合は、配管サイズ、流量範囲、流体の種類、設置要件などの要素を考慮することが重要です。流量測定の専門家に相談することは、企業が特定の用途に最適な超音波流量計を決定するのに役立ちます。
結論として、超音波流量計は、幅広い業界で流量を測定するための信頼性が高く正確な技術です。非侵入的な性質、多用途性、精度、メンテナンスの手間がかからないため、流量測定機能の向上を目指す企業にとって人気の選択肢となっています。超音波流量計の仕組みとその利点を理解することで、企業は自社の運用に流量測定テクノロジーを選択する際に情報に基づいた意思決定を行うことができます。
