Ultrasonic Volumetric FlowmeterThe System 1010PV ultrasonic volumetric flowmeter automatically compensates for product viscosity changes, making it suitable for pipelines carrying crude oil, refined petroleum or liquified gas, or for custody transfer and checkmetering applications. It displays volumetric flow and outputs in RS232, pulse rate, 0Ā10 V and 4Ā20 mADC formats. Communication protocols can be provided for various networks.Controlotron:Ā 800-275-8479; www.controlotron.com
