Product Description

Accurately measure the flow rate of relatively clean, non-aerated liquids like potable water, raw water, cooling water, de-ionized or reverse-osmosis water, oils and chemicals in full pipes. Ultrasonic transducers mount on the outside of a pipe without shutting down flow. Flow rate is displayed on the large, backlit display, along with total volume, signal strength, relay status, and other diagnostic values. Use the built-in control relays as flow alarms or volume totalization. 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.The TTFM 6.1 Transit Time Flow Meter operates by measuring the “transit time” or “time of flight” for ultrasonic sound pulses transmitted from one transducer to another. Depending on the mounting configuration, the signal may cross the pipe once, twice or four times. To measure flow the transit time is compared between ultrasonic signals travelling upstream and downstream.TTFM 6.1 Standard Features Include:
- One pair of SE16B ultrasonic transducers – clamp-on for 2” to 48” (50 mm to 1200 mm) pipes
