Hệ thống đo lưu lượng bằng siêu âm DF868

Mô tả sản phẩm

DF868 ultrasonic liquid flowmeter is a fixed-installation meter based on our award-winning TransPort PT868 portable ultrasonic liquid flowmeter. The DF868 is available with two built-in measuring modes. Using clamp-on flow transducers, the DF868 flowmeter measures flow rate through metal, plastic or even concrete-lined pipes without penetrating the pipe wall.

Transit-Time mode, with advanced signal coding and correlation detection methods, provides drift-free flow measurements in ultraclean to dirty liquids. This mode handles 80 percent of multiphase liquids-including fluids with gas bubbles, liquid droplets and entrained solids-that previously required Doppler-type meters because conventional transit-time meters failed. Using advanced technology available only from GE Panametrics, an innovative TransFlection mode expands the DF868 flowmeter’s measuring capabilities to include applications previously handled only by Doppler meters, such as raw sewage, sludge, slurries and other extremely attenuating multiphase fluids. An optional dual-channel/dual-path model can be configured for a variety of uses including flow measurement in two different pipes, leak detection by measuring at two different locations on the same pipe and dual-path measurement at one location for maximum accuracy.
