DPU1809-GF200-A1

RYD DPU1809-GF200-A1 is a Ø18x9mm 200kHz ultrasonic transducer designed for gas flow measurement. As a dedicated gas flow transducer it works with ambient pressure below 0.3MPa and shows resistance to natural gas and weak acid and alkali, with IP65 protection and 0.2mm PTFE wire termination for reliable connection in meter assemblies. The element delivers integrated sensitivity above 3V with 40dB gain for a clean flow signal, weighs about 3.5g, and operates from -20℃ to +70℃, fitting gas metering designs where stable transit-time performance is the basis of measurement accuracy. Manufactured under RYD ISO9001 quality system. Customization available: cable specification and signal interface, protective treatment and beam tuning can be configured per your meter design; new designs can be developed for volume projects. Target scenarios: gas flow metering, industrial equipment, automotive systems and smart home gas appliances.
