LG16 Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – Compact Liquid Flow Meter for OEM Applications

LG16 Liquid Flow Meter Series
Compact Liquid Flow Meter for OEM Applications
 Liquid flow rates up to 5000 µl/min
 Resolutions down to sub nl/min
 Totally non-invasive, pressures up to 200 bar
 Digital I²C interface or analog out 0-5 V
Product Summary
The LG16 Liquid Flow Meter series enables fast, non-
invasive measurements of very low liquid flow rates
below 5 ml/min. This product line is especially suited
for OEM volume applications requiring small sized
components with high performance at low cost.
Excellent chemical resistance and bio-compatibility
are ensured: The flow path of the LG16 Liquid Flow
Sensor is formed by a straight-thru glass capillary
and end fittings. There are no obstacles in the flow
path
Interface Options
Digital
- I2C-Bus
Analog
- Voltage Output (0-5 V)
