The low-cost and complete digital flow sensor is suitable for use in high-volume consumer and industrial markets

Flow measurement is often seen as a difficult and time-consuming function that requires specialist engineering expertise and knowhow. Most flow sensors available in the market follow a ‘one-size-fits-all’ rule, which limits customisation and have their own integrated processing circuitry to implement functions and algorithms – virtually inaccessible to users.

With the new FLS110 flow sensor, flow measurement can now be incorporated into virtually any product or system. Its small size makes it perfect to be fit into any product and be positioned where measurements matter.

The FLS110 flow sensor measures a flow rate across a wide measurement range of 0.001 to over 500 standard litres per minute (slm). It delivers a fully temperature-compensated and reliable flow signal that is optimised for fast scale-up and cost-effective mass production.

Target applications include: 

• Active filter monitoring in vacuum cleaners, air-conditioning units and other consumer appliances
• Pipe blockage detection in industrial and domestic gas-detection products and systems
• Air pump monitoring and control in both consumer and industrial applications
• Portable healthcare equipment such as smart inhalers and fitness monitoring masks.

Additionally, the FLS110 flow sensing solution allows seamless integration of hardware and software with mechanical and fluidic components. A full package of electronic, mechanical and fluidic engineering support comprising of: flow sensing firmware, configurable software, different customisable FLS110 operating modes depending on the application requirements, design guides and time-reducing application engineering support, helps customers decide the ideal balance of performance versus cost.

FLS110 is integrated into a 6-pin DFN package, having a footprint of just 3.5 x 3.5 mm, is reflow solderable and shipped in tape and reel for automated product assembly.

Samples are available now and are being supplied within a product evaluation kit. Volume production of the new sensor will start in the first half of 2021.
