Questions & Answers

Our data collection system has a powered 4-20mA loop, this device also has a powered 4-20mA loop, is there a way to turn off the power to the loop in the FDT-25W and let our DAQ power the loop?

Asked by: Electrical Engineer

Thank you for your inquiry! The FDT-25W can be wired for an active or passive 4-20 loop. If power is supplied by the data acquisition system you will use 23 (AO+) and 25 (LPIN) rather than 23 and 24.

Does the unit come with the red/ blue transducer cables? It does not show up under "whats included" and the model number "TCH" is not under the accessories page.

Asked by: dwilson01

Thank you for your inquiry. The transducer is included for pipe diameters from 3/4 to 4 inch which is found in the Accessories Tab.

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.

Good afternoon. When there is no liquid circulation in the pipe and the meter also indicates a instant value of flow, how to solve this? How can I reset it or put a minimum cut on it? BR

Will this flow meter work with a refrigerant as the liquid?

Asked by: Exergy Engineer

Thank you for your inquiry! This flow meter will work with nearly all clean liquids. Menu 20 in the programming can be used to select standard fluid types like water or oil. For non standard fluids not listed in menu 20 the fluid parameters can be entered in menus 21-23 to accurately represent the process media.

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.
