Reduced lead times of our liquid flow sensors

We are reducing our lead times for our liquid flow sensor products, effective immediately.

No alternate text provided — Reduced lead times

Our evaluation kits are available within 4 weeks and the liquid flow sensors within 8 to 12 weeks. Of course, our products can still be ordered via distribution and will be delivered overnight for first tests and evaluations.

Are you working on a device or application in the field of analytical instruments, life sciences, medical technology, or industrial automation where a sensor is needed? Order your sensor today.

Single-Use liquid flow sensor for biomedical applications

Safe, precise, and reliable measurement of low flow rates in medical environment has never been so easy: The single-use liquid flow sensors of the LD20 series measure the liquid flow rate directly and at the point of interest for a more effective patient treatment and improved safety. Nowadays, keywords and trends such as point-of-care, patient compliance, complex drug administering, and wearable designs demand the development of smart medical devices. The LD20 series combines Sensirion’s proven liquid flow sensing technology with a single-use, cost-optimized design for high volume applications in the medical, life-science or food industry. The sensor provides a bidirectional measurement of flow rates from 1000 ml/h down to single-digit ml/h, while it as well reliably detects common failure modes such as occlusion, free flow, or air bubbles with unprecedented speed and sensitivity. The LD20 series optimizes costs by reducing the flow sensor to its bare minimum while still ensuring easy fluidic, electrical and mechanical connections. Barbed or luer lock fittings guarantee secure and straight-forward integration into the fluidic line: for example, into a catheter or an infusion set. Inert wetted materials provide outstanding chemical resistance and excellent media compatibility. When using a sensor of the LD20 series, drug delivery can be measured precisely and in real time. Consequentially, drug therapies become more effective, as they become easier to monitor and control. The LD20 liquid flow sensor series enables medical device manufacturers to enhance the safety, performance, and reliability of their products for the benefit of patients and care givers.

LG01

Combined liquid flow switch and bubble detector

The LG01 liquid flow switch detects ultra-low liquid flow rates or the presence of air in fluidic systems. It therefore makes them more reliable. The detection of liquid flows is possible within the range of a few ml/min and less. The sensor's output signal of either 0 or 5 Volts indicates if the current flow rate is above or below the specified flow switch threshold. At flow rates above the threshold, air bubbles can be identified by generating a low (0V) output. The measurement principle of the LG01 liquid flow switch allows detecting the current state of fluid through the wall of its internal glass capillary. Thus, the sensor provides highest compatibility with biological processes and an excellent chemical resistance. Measurements of the liquid flow switch are performed with a response time of less than 100 ms.

LG16

For compact integration into instruments and other closed systems

The LG16 liquid flow meters offer Sensirion’s CMOSens® microsensors in a compact and stripped-down housing for integration into instruments and other closed systems. With five different flow ranges, calibration options for different media (H₂O and/or hydrocarbons), and digital I²C interface, the LG16 liquid flow meters offer a comprehensive solution for measuring low and ultra-low flow rates. All subtypes feature the strengths of Sensirion’s liquid flow meters: fully calibrated digital flow sensing, inert wetted materials (glass, PEEK, fluoropolymer), fast response times (down to 40 ms and below), and low power consumption. They offer the ideal solution for measuring highly dynamic fluidic processes, closed-loop control of microfluidic systems, bead and droplet count, or bubble detection. The 5 subtypes cover maximum flow rates from 1.5 µl/min by the smallest version (LG16-0025) up to 10 ml/min (LG16-2000) for water and aqueous solutions. With hydrocarbon liquids such as oils, organic solvents, fuel, or lubricants, flow rates up to 80 ml/min can be measured (see LG16-2000HC-D). The LG16 liquid flow meters have their 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 SLx liquid flow meters with their robust interface for plug-and-play operation.

Where size matters: planar microfluidic glass package

With a tiny footprint of only 10x10 mm², Sensirion’s LPG10 liquid flow sensor series provides outstanding performance and speed in measuring liquid flow in a planar microfluidic glass substrate with down-mount fluidic ports for a highly compact integration into any fluidic manifold system. It is thus ideal for high-volume applications with strict space limitations. Two core technologies are combined at this point: microfluidics chips and digital microsensor chips. This unique approach enables measurement of liquid flow inside a cost-efficient planar glass substrate. The digital microsensor chip provides the full signal processing functionality for a fully calibrated, temperature compensated, and linearized digital output. The LPG10 series is a smart sensor solution offering flow rates from the low microliter per minute range up to 1 ml/min. Glass as the only wetted material ensures optimum compatibility with biological and pharmaceutical processes. Due to its small thermal mass, response times below 30 ms can be reached. This means that even highly dynamic changes in the flow rate (e.g. produced by pulsating micropumps) can be monitored with this sensor. One step further: the sensor’s signal can be used for a closed-loop control to reach continuous flows even with pulsating pump mechanisms. The small form factor literally allows direct and highly accurate measurements of the flow at any point of interest in a fluidic system. In addition, real time detection of failures such as clogging, air bubbles or leaks comes along for free.
