Natural Gas Metering With Ultrasound - A New Dimension of Metering

Introductory concepts for the measurement of natural gas using the principle of pulse transit time measurement are discussed. Diagnostics typical to multipath transit time meters using ultrasonic pulses are described and guidance provided regarding their interpretation. Multipath arrangements and transducer types are also addressed. Guidance is provided on the proper application and on-going operation of ultrasonic meters to assure continued measurement integrity.
