The Daniel 3410 series gas ultrasonic meter has dual transmitters and meters in a single body to help natural gas operators and pipelines improve reliability and efficiency. The device permits two completely independent measurements with the installation of a single flowmeter. The 3415 (four-path + one-path) and 3416 (four-path + two-path) gas ultrasonic flowmeters combine a four-path fiscal meter with an additional check meter, while the 3417 (four-path + four-path) meter provides two fiscal meters for full redundancy and equal accuracy within one meter body. This two-in-one redundant design gives continuous online verification of custody transfer measurement integrity, device health, and process conditions, and improves fiscal metering confidence and regulatory compliance.
Both Daniel 3415 and 3416 gas ultrasonic meters measure flow using four horizontal chordal paths in addition to a reflective path dedicated to verification of the primary measurement. For enhanced immunity to pipe wall contamination, the 3416 meter is equipped with an additional vertical reflective path to detect liquid or very thin layers of contamination at the bottom of the meter that otherwise remain completely hidden in a direct-path meter design. This allows reliable monitoring of process changes before they affect measurement, reducing calibration frequency and enabling maintenance based on conditions.
