Series DFX Ultrasonic Doppler Flow Meters measure flow of liquids that contain useful sonic reflectors¹ suspended within the liquid. The DFX flow meter operates by transmitting an ultrasonic sound from its transmitting transducer through the pipe wall into the flowing liquid. The sound will be reflected by the the reflectors and recorded by the receiving transducer. (read more)

Series TFXL is an ultrasonic flow meter that clamps on to the outside of a pipe. It is designed to replace mechanical flow meters in applications where liquid conditions tend to damage or impede mechanical flow meter operation. Installation of the TFXL is cost effective and the meter requires no maintenance. The unit may be ordered with or without a local display. (read more)

Series TFXP Portable Transit Time Flow Meters feature the world's most advanced non-invasive flow measurement technology – providing a measuring system with unsurpassed accuracy, ease of installation and dependability. (read more)

Series UFX Doppler Flow Meters provide accurate and reliable flow velocity assessments in closed pipe, liquid systems. UFX requires that the liquid be either solids-bearing or aerated at a minimum of 100 ppm. The product utilizes a single, hand-held transducer which is placed on the outside of metal or plastic pipe.

FLEXIM's WaveInjector® has been specially engineered for high-temperature flow measurement applications. Using patented technology, the WaveInjector thermally separates the ultrasonic transducers from the hot pipe, allowing measurement at temperatures up to 400°. The ultrasonic transducers are simply clamped to the outer surface of the pipe, using coupling plates for acoustic contact. (read more)

CSLFB Ultrasonic Flow Transmitters are ideal for measuring flow in most clean liquids and many liquids with entrained solids. Applications include monitoring flow rates of chilled or heated water as part of a green technology program and in municipal, process, and industrial systems. There is no need to calibrate the transmitter to fluid temperature, viscosity, or density. (read more)

This new model OCF 4.0 Open Channel Flow Monitor uses a non-contacting ultrasonic sensor to measure wastewater flow through flumes or weirs. (read more)

DFM 5.0 Doppler Flow Meter

Measure flow from outside a pipe. The Greyline DFM 5.0 is designed for "difficult liquids" that would damage regular flow meters - wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. There is no obstruction to flow and no pressure drop. The standard, strap-on ultrasonic sensor fits any pipe 1/2" (12.5 mm) Inside Diameter or larger. (read more)
