Ultrasonic meter
Heat Meter Accuracy Testing, published by the Department for Business, Energy & Industrial Strategy in November 2016, suggests that:
Ultrasonic flow measurement using the transit-time differential method is now one of the most universally applied flow metering processes. Flow is generally measured using the bidirectional ultrasonic technique based on the transit time method, with proven long-term stability and accuracy. Two ultrasonic transducers are used to send the sound signal both against and with the flow direction. The ultrasonic signal travelling with the flow direction reaches the opposite transducer first. The time difference between the two signals can be converted to a flow velocity and thus a volume. Ultrasonic meters are non-invasive and have no moving parts. Long unimpeded inlet runs are needed for accurate measurement. |
