/15 | OPTIMA-S-FM Measurement The air flow transmitter measures the flow velocity dependent dynamic pressure on the measurement probe. For both OEM/Communication types, BM and SA 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.
