Gill Instruments has improved the sonic temperature performance of the company’s 3-axis anemometer range to an accuracy of greater than ±1% in readings between -18°C and +30°C. The improvement has been achieved by using the US National Physical Laboratory’s advanced sound profiling facility as well as research using in-house computational fluid dynamics - CFD modelling - to examine transducer production.
Anemometers are used throughout the meteorological research and industrial industries. They simultane
US and European asphalt paving needs are different, but some firms are bridging that gap, reports Mike Woof. With a clear differentiation between the US and European asphalt paving markets, manufacturers from the latter are now developing machines aimed at the former. The US and European markets for paving machines have developed along very different lines. North American pavers are designed for high throughputs and high paving rates, having been designed to meet a need to build roads over long distances wi
