FLOW METER The SITRANS FUH1010 precision volume clamp-on non-intrusive ultrasonic flowmeter is ideal for numerous hydrocarbon applications carrying crude oil, refined petroleum or liquefied gas. It offers automatic “Reynolds Number” compensation for changes in liquid viscosity and temperature, making it a perfect match for measuring liquids with a wide viscosity range. In addition, automatic gross volume compensation is also provided. The meter comes in single, dual and optional four path configurations. The multichannel version provides higher accuracy, especially in applications with limited straight run or a poor flow profile. There are three enclosures to choose from: wall mount, wall mount explosionproof and compact explosionproof. Application examples include precision volume measurement in leak detection systems, scraper and pig detection, and chemical processing.
