Greyline Instruments’ TTFM 6.1 transit-time flowmeter has powerful, new digital signal processing and advanced algorithms and provides easy and accurate flow measurement of clean and relatively clean fluids, including water, oil, and chemicals. The clamp-on technology does not require pipe penetration, cutting or welding. It installs in typically less than 30 minutes and a high accuracy with 25-1 turndown. It offers isolated 4-20mA output for flow rate, two relays for pulse output or alarms, and a 26 million-point data logger for greater flexibility of data monitoring and control. 315-788-9500; www.greyline.com.
