The latest PFM Tester Series from 2565 Flo-tech now features an internal safety pressure relief disc.

The proven PFM products have a long track record for measuring flow, pressure, temperature and power on mobile hydraulic equipment. However this improved version now features and internal burst disc designed to ensure that in the event of over-pressurisation, fluid is safely allowed to bypass the load valve and remain within the hydraulic system. The feature means that no fluids will escape from the tester, reducing maintenance costs and preventing the need for environmental clean-up from spills. The internal burst disc is also field-replaceable, should an over- pressurisation occur. The PFM Tester uses a turbine rotor and a magnetic pick-up to monitor the frequency pulse output from the rotor and measure flow. Volumetric flow rate is displayed on an LCD or sent through a digital output to a PC. The PFM Series units are said to provide reliable readings with an accuracy of 1% of full scale and a repeatability of 0.2%. Temperature is measured with an internal sensor, and pressure is measured by analogue gauge or high-sensitivity digital sensor. For ease of use and safety, all testers have loading valves with fingertip control and pressure surge protection.

    Integrated construction software offers an effective planning solution - *Mark Nichols writes. In a world where resources are limited, 20 year designing and building in a sustainable way is more critical than ever. By employing today's software tools it is possible to reduce the total cost of construction of a new highway, while reducing operating costs and environmental impacts. The path to achieving the greatest gains is to take a holistic approach to the plan, design, construct and operate process from t
  • Advances in US paving machines and material feeders

    Paving machines vary considerably in North America compared with those units used elsewhere. On a worldwide basis, pavers with tamper bar screeds are popular having been developed in Europe and also favoured by Japanese and Chinese firms. But in the US the length of highways to be constructed resulted in a focus on high production pavers, which still continues today. North America and Latin America are key markets for these machines, with Australia being one of the few territories to employ both European an
