Mobile mapping – the future of surveying

Information from VI Instruments The world of data collection for surveying and GIS has changed. Where traditionally single points were selected and measured, today’s technologies allow the registering of massive amounts of points with unprecedented detail. Mobile mapping takes this to the extreme: complete information along hundreds of kilometres of road can be collected in […]

Trouble-free pipe manufacturing

It is said that it is still common practice to cut open a pipe coupling lengthwise, trace its contour on paper and measure its angle manually with an angle gauge. It is practically impossible to avoid measurement errors, and the whole process is very time-consuming. In practice, complex pipe components are only measured at a […]

Energy- and cost-efficient battery cabinet

Heat is the number one killer of batteries. A seemingly mere 10°C increase from the ideal operating temperature of 20°C halves the life of a battery. So at 40°C, a battery that should last ten years may last only 2,5 years. This drives up replacement costs and severely increases the impact on the environment. SiteStar […]

Insertion type flow sensors

Sperosens supplies the Weber Captor range of flow sensors for the detection of flow, paste, liquid or gaseous substances. The Captor range offers calorimetric flow sensors, using heat energy to produce an electric signal which is proportional with the actual flow rate. The sensors provide high accuracy measurement of flow including very low flow rates. […]
