Features


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.

Does this model FDT-25W work on ductile iron pipe (18.75mm thick) having inner lining of cement mortar (12.5 mm thick)?

Asked by: Anonymous
Thank you for your inquiry about the ultrasonic flow meter. Unfortunately, it will not work as a result of the liner indicated.

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.

I'm looking for a flow meter that I can move around my plant to check process water flow at different locations. I would need one that can operate on Steel and PVC piping ranging from 2" to 10". Would this be a good meter for my application?

Asked by: Racecar64
Thank you for your inquiry about an ultrasonic flow meter. There is a more convenient hand held version, FDT-25, which is portable and will have a transducer that will range from 3/4 to 4 inch and will need to purchase a 2nd transducer for larger pipes, STD-HM.

We would like to test mount the transducers on multiple locations along the pipe before selecting the final measurement location. Is enough acoustic gel provided to remount the transducers 3-4 times?

Asked by: Brandon B
Thank you for your inquiry! In this case it would be recommended to purchase additional gel as having a sufficient amount is very important in obtaining accurate readings. Extra gel can be found with the part number STDGEL under the accessories tab.

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.

Asked by: Alex N
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.

what is the thermistor type that is used for monitoring the temperature? on page 12 of the manual is says connect PT100. is this in parallel to the thermistor?

Asked by: Winnipeg Customer
Thank you for your inquiry! The FDT-25W can accept a 3 wire 100 ohm RTD input. This temperature sensor is optional and will not be included with the unit.

FDT-25W Is it Suitable for "Bitumen" ?

Asked by: Sameh
Thank you for your inquiry about the ultrasonic flow meter. Unfortunately, the FDT-25W sensor will not be suitable to measure Bitumen. The FHG-1000 series positive displacement flow meter would be more suitable a high viscous liquid.
