 14.02.2012 Компания Omega Engineering inc., мировой производитель измерительной техники, сообщила о выпуске нового ультразвукового измерителя скорости потока FDT-21.
FDT-21 ultrasonic flowmeter is designed to measure the fluid velocity of liquid in a full/closed pipe. It is a handheld measurement system which is both easy to install and use. The FDT-21 operates according to the difference in the transit time of flight measured, and determines the flow velocity by measuring the travel time of a pulse from one transducer to the next. Flow in the same direction takes less time to travel to the second transducer than does flow in the opposite direction. Electroacoustic transducers receive and emit brief ultrasonic pulses through the liquid of the pipe.
