Pulsar Measurement – TTFM 6.1 – Transit-Time Ultrasonic Flow Meter for Clean Fluids in Pipes

The TTFM 6.1 Transit-Time Flow Meter is a versatile device ideal for a wide range of applications, including clean water, chemicals, and fuel oils. It operates by measuring the time difference of ultrasonic sound pulses between transducers mounted on a pipe. With easy setup using a keypad, this flow meter offers accurate measurements without the need for expertise. Its non-contacting design and low maintenance make it a reliable choice for both retrofits and new installations, ensuring long-term accuracy and peace of mind.
