Digital Handheld Ultrasonic Flow Meter

The FDT-25 handheld ultrasonic flowmeter is designed to work with clamp-on transducers to enable the flow of a liquid within a closed pipe to be measured accurately without needing to insert any mechanical parts through the pipe wall or protrude into the flow system.

Using ultrasonic transit time techniques, the FDT-25 is controlled by a micro-processor system which contains a wide range of data that enables it to be used with pipes with an outside diameter ranging from 15mm up to 6000mm (depending on model) and constructed of almost any material. The instrument will also operate over a wide range of fluid temperatures.

Flow Meter comes complete with:
1 ea. Handheld Ultrasonic Flow Meter
2 ea. Standard Clamp on Transducers for Medium size
2 ea. Transducer Chains
2 ea. Transducer Clamps
1 ea. 3M Ruler
1 ea. Acoustic gel for Standard Transducers
1 ea. RS232 Computer Cable
Transducers for larger pipe sizes and extended temperature ranges are available in the Accessories Section for an additional charge.
