We are leaders in the market for providing best range of Air and Gas Velocity Transmitter and Ultrasonic Level Indicator
| The FF86 series air velocity transmitters were developed to obtain accurate measuring results over a wide range of velocities and temperature. High-quality hot film sensor elements based on cutting-edge thin film technology ensure maximum sensitivity, even at lowest mass flows. At the same time, the innovative probe design produces reliable measuring results at high flow velocities of up to 40m/s (8000ft/min). The integrated temperature compensation minimizes the temperature cross-sensitivity of the FF86 series which, combined with the robust mechanical design, allows it to be used at process temperatures between-40 to 120C (-40 to 248f). In addition to air velocity & temperature values, the transmitter calculates the volumetric flow rate in m3/min or ft3/min. the cross section of the duct needs to be determined for this purpose and the volumetric flow rate can displayed and directed to one of the analogue outputs. The configuration software included in the scope of supply allows choosing the appropriate output parameter and freely scaling the display range & signal level of the two analogue outputs. In addition user-friendly calibration of the air velocity & temperature and the adjustment of key parameters (e.g. response time of the velocity measurement, low flow cut off points, etc.) are supported as well. | ||
| An optional illuminated display with two control buttons integrated in the cover is available. In addition, this enables changes of the configuration to be made directly on the unit. The FF86 series can be used to measure the velocity of other gasses as well, although a correction has to be applied to the unit at the factory.
