The Digiflow CTF878 clamp-on gas flow meter utilizes a new technology called correlation tag (patented) to determine gas flow rate. This technique is very different from traditional ultrasonic transit-time measurement and is well-suited for gas applications. The Digiflow CTF878 can measure a wide range of velocities in small to large pipes up to 150 ft/s (46 m/s), giving it broad applicability in gas flow measurement. It is used on plastic and metal pipes from 6 to 30 in (150 to 750 mm)in diameter. Accuracy is excellent—better than ±2 percent of reading—with repeatability of ±0.6 percent of reading. The turndown ratio is 43-to-1
