Controlotron's Ultrasonic Flowmeter
Nonintrusive System 1010PV ultrasonic flowmeter automatically compensates for product viscosity changes, making it suitable for pipelines carrying crude oil, refined petroleum or liquefied gas, and for custody transfer and checkmeter applications. Volumetric flow is displayed and output in RS232, pulse rate, 0-10 V, and 4-20 mA formats. If mass flow measurement or interface detection is required, it can be supplied with density and API outputs.
