Product Overview
BBFM-Q500K is a 500 kHz ultrasonic transducer for ultrasonic gas flow meters and gas metering equipment. It can be integrated as a transmitting and receiving acoustic element in gas-flow measurement systems. Its 5° nominal beam angle supports acoustic measurement paths that require a concentrated ultrasonic beam.
The transducer provides IP65 protection and an operating temperature range of -20 to 70 °C. It is suitable for gas flow meters, metering modules, and OEM ultrasonic measurement equipment.
