TTFM 6.1 Transit Time Flow Meter
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.
