Technology Features & Specifications
Flow measurement is often challenging due to its dynamic quality and also dependence on sensor location and integration method. As such, proxy measurements with expensive pumps, hall-effect sensors or drift-prone pressure measurements are often used instead.
This company's sensor is built around a patented combination of materials, processes and design, offering improved thermal interaction with a fluid for high sensing performance. It has no moving parts, is highly robust, and ideally suited for cost-effective high-volume production. The flow sensing chips use a temperature-adjustable, tungsten hotwire micro-heater, which is fully embedded within a stress-compensated membrane. A temperature sensor is integrated alongside for ambient temperature measurement. They use a DFN package, are reflow solderable and shipped in tape and reel for automated pick and place assembly.
This company’s approach is to offer not just a high performance, flow sensing component but a complete digital flow sensing solution designed for easy integration. Customers can customize it to their unique needs to deliver the ideal balance of performance versus cost. It comes with a proprietary firmware (including sensor control, sensor reading, temperature compensation and other algorithms) designed and structured for easy integration. To help customers overcome the mechanical and fluidic challenges of integrating a flow sensor into their application, the company has used its fluidics and engineering knowhow to develop a flow sensor for bypass systems to cover flow rates in excess of 500 slm.
