Ultrasonic flow sensor with pipe for development with EVM430-FR6047 & EVM430-FR6043


The Audiowell ultrasonic flow sensors are designed to work with with brass or poylmer plastic pipes of sizes DN15, DN20 & DN25 to aid in the development process when working with evaluation modules for our MSP430FR600x Ultrasonic Sensing MSP430™ Microcontrollers, specifically the EVM430-FR6047 and EVM430-FR6043 which are available for development of water flow meters. These Audiowell ultrasonic flow sensors are designed to be used in conjuction with the water flow meter software, found in the Ultrasonic design center. Using these tools together allow you to quickly develop water flow meters that support a wide range of flow rates.
