Clever pumping: making water industry’s pumps intelligent

  Climate change, increasing water demands due to global urbanisation, and the legal obligations of the EU’s Water Framework Directive are all making the water sector an attractive arena for technologies that can help reduce costs and contribute to reducing the effects of climate change. It is against this backdrop that the demand for intelligent […]

Measuring the transverse sensitivity of vibration transducers

  The National Metrology Institute of South Africa (NMISA) has implemented a system to measure the transverse sensitivity of vibration transducers. As a mechanical device, the principle sensing axis of an accelerometer is not 100% perpendicular to the mounting axis. This gives rise to the effect that the accelerometer will produce an electrical output even […]

Understanding the benefits of solar power

  Using solar energy would be a logical route for us to follow in an effort to alleviate the energy shortage. But we don’t. There are several good reasons why South Africans are reticent, amongst them being the cost of installation, lack of a clear understanding about what is available and, the fact that feeding […]

Testing the limits of IEEE 802.11ac wireless networking standard

  The evolving wide-bandwidth IEEE 802.11ac communications standard brings new benefits to users but new challenges to those tasked with testing products based on this standard. As the IEEE 802.11ac wireless standard evolves, it continues to breed new challenges for those tasked with testing and measuring these wireless systems. As products based on the IEEE […]
