Product Details

LG01-2000A Liquid Flow Switch & Bubble Detectors

The LG01-2000A family of liquid flow switches from Sensirion are able to detect liquid flow by millilitres per minute (ml/min). It also provides bubble detection.
When the flow rate is more than the desired flow switch point, the output signal is 5 V. If the flow rate is lower than this point the output signal is 0 V. This is also the case for when air/bubbles are sensed within the sensor’s flow channel.
This non-invasive liquid flow switch has a straight glass capillary flow path. This also enables chemical resistance and bio-compatibility.
An additional Connectivity Kit can be purchased separately for the LG01 liquid flow switches.
