Greyline - Model TTFM 6.1 - Transit Time Flow Meter
Accurately measure the flow rate of relatively clean, non-aerated liquids. Ultrasonic transducers mount on the outside of a pipe without shutting down flow. Flow rate is displayed on the large, back-lit display, along with total volume, signal strength, relay status, and other diagnostic values. Use the built-in control relays as flow alarms or volume totalisation. Connect the isolated 4-20mA output to PLC's or controllers. A 128MB data logger is standard, capable of capturing up to 26 million data points. Optional MODBUS RTU via RS-485 available for connection to automation systems. The TTFM 6.1 works on a wide range of pipe sizes and materials including carbon steel, stainless steel, ductile iron, concrete lined ductile iron, cast iron, PVC, PVDF, fiberglass, copper, brass, aluminum and pipes with bonded liners including epoxy, rubber and Teflon.
