Aiming at the problem that large influence of environmental factors

poor reliability

and large differences between the measurement range of standard parts and engineering requirements in the process of liquid flow measurement in aviation field

technical research on turbine flow measurement characteristics is carried out.Using micro-signal processing technology

micro-programmed control unit（MCU） technology

magnetic shielding technology

data fusion technology

and transient simulation technology

a small-volume

a highly reliable liquid turbine flow sensor is designed

which realizes stable and reliable measurement of small volume

wide range liquid flow.The simulation and measurement results show that the sensor is small in size

light in weight

it has good repeatability

low starting flow（1.677 L/min）

strong anti-electromagnetic interference ability

measurement precision can reach 0.91 %FS

it is stable and reliable for long-term operation

and meets the（0～30）L/min measurement requirements of application engineering.
