Honeywell HAF Series Digital Airflow Sensor for Air, Gas, 0 l/min Min, 100 L/min Max

This Zephyr digital airflow sensor from Honeywell is designed with cutting edge technology to accurately measure the flow of air and other non-corrosive gases. It features a choice of installation options, including a 22mm tapered male fitting, a G 3/8 threaded female port and manifold mounting. This makes it a flexible component that can suit a variety of standard fixtures. To add to its reliability, this sensor has a linear output that ensures reduced output noise in operation. It also has high sensitivity at a flow rate of 100SLPM (standard litres per minute), resulting in a fast response time of 1ms. This feature makes it appropriate for medical and industrial applications.

• Wide supply voltage range of 3V to 10V DC allows for flexibility of use in different applications
• ASIC-based (application-specific integrated circuit) digital output makes integration to the PCB (printed circuit board) easy
• High 12-bit resolution enhances sensitivity to small changes in airflow

• Process-control gas monitoring
• Ventricular assist devices
• Spirometers

This depends on a number of factors, including the application itself. You can check out Honeywell's TEB (Total Error Band) information, which will provide you with real data to help with your decision.
