The SLI, SLS, SLQ, and SLG liquid flow meters all feature a robust IPxx protected housing and the same 4-pin M8 connector. In combination with the SCC1-USB, RS485, or analog sensor cables, they provide a modular solution that covers a wide range of flow rates from single-digit nanoliters per minute up to several hundred milliliters per minute, and a suitable electrical interface for almost any environment:
The SLx liquid flow meters are the first choice for standalone applications in industrial automation systems, laboratory set-ups, bench-top testing, and technology evaluation. The robust housing (IP53 or higher) protects them from dust or accidental spills.
The SLG liquid flow meters are the perfect solution for dynamic liquid flow monitoring in cutting edge Ultra-High-Pressure Liquid Chromatography (UHPLC) and other applications requiring precise measurement of ultra-low flow rates.
A highly sensitive CMOSens® microchip detects the mass flow through the wall of the fused silica flow channel. The flow channel withstands pressures up to 1200 bar / 17500 psi. At the same time the response time for measurements is 40 ms only. The combination of these properties enables the high-end devices of the SLG series to be especially suited for monitoring dynamic flow rates in cutting-edge chromatography systems. Great repeatability for analyses - the most important criterion in HPLC and microfluidic systems - is ensured. The maximum flow rate of the SLG-0075 is 5 µl/min in precision mode and 20 µl/min in extended mode. The SLG-0025 provides reliable liquid flow measurements down to 70 nl/min and even below. The SLG-0150 completes the SLG series with a slightly higher flow range than the SLG-0075, at a reduced pressure drop. It is the first choice for laboratory setups and leakage detection at moderate pressures up to 500 bar.
The SLG liquid flow meters in combination with one of the SCC1 sensor cables offers a modular solution with a suitable electrical interface for almost any environment:

The SFM3300 mass flow meter is a sensor for proximal flow measurement in respiratory applications such as ventilation or anesthesia. There are two versions available: the SFM3300-AW is autoclavable and washable and the SFM3300-D is single-use.
The SFM3300 features outstanding measuring accuracy and robustness as well as a short signal processing time. The digital flow sensor measures bidirectional flow volumes of up to 250 slm and is fully calibrated for air, N2 and O2 gases. The special design of the flow channel results in a low dead space volume and the slightly greater pressure drop ensures more stability compared to variable inlet conditions. The sensor also features medical cones for pneumatic connection to the respiratory cycle and has a mechanical interface for a user-friendly electrical connection. Thanks to its performance characteristics, the SFM3300 mass flow meter is ideally suited for single-use proximal flow measurements in medical ventilation, hospital applications, residential care applications and emergency situations.
Like all Sensirion sensors, the SFM3300 is based on the innovative CMOSens® Technology, which combines the sensor element and processing electronics on a single, tiny CMOS microchip. The CMOSens® mass flow sensor offers durably stable and interference-free measurement and enables a very fast and highly precise sensor signal.
