APPLICATION
FloXacts™ are used in air conditioning and ventilation systems to measure air flow. The VAV unit is controlled by a thermostat or DDC controller and varies the air volume based on cooling and/or ventilation requirements. This results in significant savings in fan energy because, when there is little or no cooling demand, the valve can be partially or even completely closed. The VAV unit can also be used for air quality control. Depending on the CO2 concentration, more or less fresh air is supplied. The units are available in single- and double-walled versions.
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.
