APPLICATION
The FloXact™-L is used to measure air velocity / air volume in HVAC systems. The design is suitable for easy installation in new and renovated VAV terminals. The FloXact™-L works according to the pitot tube principle and measures the total and static pressure components of the air flow. The sensor determines the average air velocity, measured over 2×6, 2×8, 2×10 or 2×12 measuring points, depending on the size. The unique shape of the measuring profile provides a linear gain of at least 2.5x Pdyn, allowing accurate measurements from an air velocity of 1.0 m/s. The FloXact™-L is available from ø200 to ø1500, but other diameters are also available on request.
FEATURES AND BENEFITS
- FloXacts™ are available in metric and imperial
- Suitable for all makes of VAV controllers with a built-in pressure transducer
- Easy installation in existing air ducts or VAV units
- 2% accuracy
- Hole distribution according to Log-Tchebycheff method.
- Average measurement over 2×6 measuring points.
- Amplification of measurement signal by at least 2.5x.
- Accurate measurement from 1.0m/s air velocity
- Rounded measuring ports make the FloXact™ insensitive to oblique or turbulent flow up to 30º in all directions relative to the profile axis.
- Extruded aluminum measuring profile
- Brass connection grommets as standard for hose internal ø4 mm. Grommets for hose internal ø6 mm available on request
- Above a length of 350 mm, the sensors are provided with an additional M6 mounting on the tip through a stable mounting in the air duct.
- The FloXact™ can be supplied with pressure transducer type DPT-FLOW-1000. The advantage of this pressure transducer is that the Kv value can be set so that the air volume can be read directly on the display and the output signal, (0(2)-10V or 0(4)-40mA, is proportional to the air volume.
- The FloXact™ can also be supplied with a pressure transducer type EPD-1000. This pressure transducer has only an output signal, 0-10V or 0-40mA, which is proportional to the pressure.
