The LG01 Liquid Flow Switch enables detection of flow of liquid in the range of ml/min. The output signal is 5V when
the flow rate is higher than the specified Flow Switch Limit and 0V below this limit or when air or bubbles are found
inside the sensors flow channel instead of liquid.
Excellent chemical resistance and bio-compatibility are ensured: The flow path
formed by a simple, straight

2.1 Operation with other Liquids than Water
Due to the measurement principle the LG01 flow switch characteristics is changing with the thermal properties of the
liquid. For aqueous solutions the data above is a good approximation.
For hydrocarbon liquids such as oil, fuel, solvents and so on the Flow Switch Limit is increased by the factors below.
