Air flow Digital vane anemometer FVAD 15-H for special applications, with ALMEMO® D6 plug Technical data and functions • The precision measuring heads and the sensor shaft are made of aluminum or stainless steel. • The flow velocity is measured with high accuracy. • Each vane anemometer is individually adjusted. The Multipoint adjustment is stored in the ALMEMO® D6 connector. • In practice, measurements in air and gases are unaffected by environmental variables such as pressure, temperature, or humidity. The low dependence of the measured value on density of the gas can be compensated for. The density can be programmed in the ALMEMO® D6 sensor menu in the ALMEMO® V7 device. Technical data Nominal conditions 22 °C ±2 K, 1013 mbar Connecting cable permanently fitted cable, with Lemo plug ALMEMO® adapter cable Lemo coupling cable, with ALMEMO® D6 plug Frequency measurement resolution 0.01 Hz • Several measuring heads can be used for measurements in water. • Some variants detect the direction of flows and display the measured value with an algebraic sign. • The robust type of construction is suitable for mobile measuring operations as well as for stationary measuring operations. • The ALMEMO® D6 plug measures the frequency signal of the rotating vane with high resolution. • 1 measuring channel is preprogrammed (ex works): Flow velocity (m/s, v). Multi-point adjustment sensor specific, saved within the ALMEMO® D6 plug of the adapter cable Refresh rate 0.5 seconds for all channels Averaging period 2 seconds, programmable from 2 General features for the ALMEMO® D6 sensors: see chapter ALMEMO® Measuring instruments Digital vane anemometer for water FVAD 11/2025 • We reserve the right to make technical changes.
