The TTFM 6.1 transit-time flow meter from Greyline Instruments has been introduced with what are said to be powerful new digital signal processing and advanced algorithms that provide easy and accurate flow measurement of clean and relatively clean fluids (water, oil, chemicals).
Benefits include: clamp-on technology that does not require pipe penetration, cutting, or welding; installation typically in less than 30 minutes; accuracy of ±1% of reading with 25:1 turndown; and, built-in 5-key calibrator, intuitive menu and backlit LCD display.
At a glance, the company says, view flow rate, flow direction, totalizer, relay status, and important diagnostic information on display.
Units are isolated 4 to 20 mA output for flow rate, and two relays provide pulse output or alarms and 26-million-point data logger.
The meter monitors flow rate, volume total, run hours, and diagnostic information through two wires with the optional MODBUS RTU serial communication option.
