Product Overview
The SUP-FVX260 vortex flowmeter is designed for flow measurement of liquids in industrial pipelines. It uses the Karman vortex street principle to detect vortices generated downstream of a shedder bar and converts the vortex frequency into the corresponding fluid flow rate.
Designed for conventional industrial applications, the FVX260 combines a streamlined structure with reliable flow measurement performance. It supports a two-wire 4-20 mA output, operates from a 24 VDC power supply, and is available in nominal diameters from DN15 to DN200.

Working Principle
The FVX260 operates according to the Karman vortex street principle. When liquid flows through the meter body and passes the shedder bar, alternating vortices are generated on both sides of the bluff body.
The vortex shedding frequency is directly proportional to the fluid velocity. The flow sensor detects the vortex frequency, from which the fluid velocity is calculated. Combined with the flowmeter diameter and calibrated instrument coefficient, the meter determines the instantaneous volumetric flow rate.

Frequently Asked Questions
Q: What medium can the SUP-FVX260 measure?
The FVX260 is specified for liquid flow measurement.
Q: What pipe sizes are available for the FVX260?
The FVX260 is available for nominal pipe sizes from DN15 to DN200.
Q: What is the maximum range ratio?
The specified range ratio is from 1:1 up to 20:1.
Q: What output signal does the FVX260 provide?
The FVX260 uses a two-wire 4-20 mA current output.
Q: What power supply does the FVX260 require?
The meter operates with a 24 VDC ±10% power supply.
Q: Is the FVX260 suitable for liquid-cooling systems?
Yes. Its compact size and lightweight design make it suitable for space-constrained installations, including densely arranged pipelines and integrated liquid-cooling equipment.
Q: How should I select the correct FVX260 size?
The meter should be selected according to the actual operating flow range rather than pipeline diameter alone. For better measurement performance, the normal operating flow should preferably fall within the middle portion of the selected measuring range.
