/12 | OPTIMA-R-FM Measurement The air flow transmitter measures the flow velocity dependent dynamic pressure on the measurement probe. The air flow volume is interpreted by the transmitter in the form of analog signal U in the 0 V ... 10 V or the 2 V ... 10 V mode from the analog output. The air flow volume q can be calculated using this analog voltage value and the nominal air flow volume Vnom of the measurement device. The Vnom values are in the table of dimensions.
