The FDT-25W ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation. The FDT-25W transit-time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This selection of the mounting method depends on pipe and liquid characteristics. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe. The FDT-25W can be used for metallic, plastic and rubber tubes. Applications include Running Water, HAVC, Water Conservation, Metallurgy, Chemical Industry, Machinery, Energy.

FDT25W comes complete with:
1 ea. Wall Mounted Ultrasonic Flow Meter
2 ea. Standard Clamp on Transducers for Pipe Sizes 3/4" to 4"
1 ea. Hexagonal Wrench
2 ea. Steel clamps
1 ea. Acoustic gel for Standard Transducers
Transducers for larger pipe sizes and extended temperature ranges are available in the Accessories Section for an additional charge.

We are using a doppler flow meter but the clenliness of the water varies quite a bit and when it is too clean we don't get accurate readings. How dirty can the water get and still be read accuratly with transit time?

Asked by: Chuck B
Thank you for your inquiry about the Transit Time ultrasonic flow meter. Transit Time works best when the liquid is clean or below 100 microns in particle size AND less than 100 ppm in concentration. In the event there is some suspended particles, it will not detect it since it is very small.

Is the FDT-25W qualified to any Electromagnetic standards (CISPR 22/32, EN61326-1, FCC Part 15, etc.)? I have some sensitive equipment near where this might go. My gut is that it won't create a problem, but it would be nice to know.

Thank you for your inquiry on the ultrasonic flow meter. Unfortunately, there is no documentation or rating for Electromagnetic standards available for this flow meter.

FDT-25W is this a totalizer as well as a flow meter?

Asked by: Chuck B
Thank you for your inquiry about the ultrasonic flow meter. Yes, it does have a line to display the total volume as well as velocity.

I can always read thru a 250 mil beaker of solution even at its dirtiest. Will transit time work?
