Accurately measuring flow rate is paramount to keeping a water treatment plant running normal. While electronic measurement devices come in many different forms, the ability to measure flow rates from outside the pipe provides ease and efficiency. The TTFM 6.1 transit time flowmeter from Greyline Instruments is designed specifically for that.
The flowmeter can be used to accurately measure the flow rate of relatively clean, nonaerated 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. The flow rate is
