Sensirion offers the compact and chemical-resistant liquid flow meter LS32-1500 for integration into instruments and other closed systems with low flow rates of up to 40 ml/min.

With a compact form factor of just 18x18x59 mm³, the LS32-1500 liquid flow meter is mechanically extremely robust. Its fast response time of 20 ms, excellent repeatability and outstanding chemical resistance make the sensor ideal for use in biomedical applications. The sensor is highly versatile and can be used in fuel cells, for example, as well as a wide range of applications in dosage control and industrial automation monitoring.

The use of high-performance stainless steel, PTFE, and PEEK ensures outstanding media-compatibility and exceptional chemical resistance. Customized solutions (e.g. downmount version for manifold systems) based on the design of the LS32-1500 are also feasible.

The LS32-1500 liquid flow meter offers a cost-efficient, compact, and reliable sensor solution for the measurement of low flow rates and is an excellent addition to the range of high quality products from Sensirion.

The LS32-1500 liquid flow meter has its largest benefit when integrated into an instrument or a closed system. For standalone applications, laboratory setups or bench-top testing, please have a look at our SLS-1500 liquid flow meter, which offers a robust interface for plug-and-play operations.
