Designed for integration in demanding flow control systems, the SLI liquid flow meter series is a high precision solution for low flow rates of liquids based on water or hydrocarbons (alcohols, solvents, oil, fuel, adhesives). Sensirion’s modular approach, which allows the liquid flow meter to be combined with several interface cables, ensures an optimal match and simplifies the integration of a liquid flow meter into a fluidic system.

The short response time and high precision of the SLI liquid flow meter allow accurate monitoring of highly dynamic processes such as fast dosing operations. As with all other Sensirion liquid flow meters, this reliable device works without any moving parts, measuring through the wall of a straight flow path. Ultimate media compatibility of all wetted parts is ensured by the exclusive use of highly inert materials (glass, PEEK and flouropolymer sealing). The robust IP65 protected housing in a compact form makes the SLI flow meter the first choice for the measurement of low flow rates from single-digit microliters to several milliliters per minute in demanding applications in the life sciences and industrial automation.
