Water calculator

Growing Blue has launched the Water Impact Index (WIIX) Calculator, a new web-based tool designed to measure and reduce the impact of human activity on local water resources. Available online at the group's website, the new calculator was designed by Growing Blue founding partner Veolia Water. The calculator expands upon current volume-based water calculators by also taking into account water resource stress factors and water quality. Paired with a traditional cost analysis to identify the ideal return on investment, the calculator represents a truer measurement of impact on a local water resource. It also offers insight into reducing that impact and can lead to potential cost savings. One of the goals of the calculator is to foster greater collaboration and continued dialogue around water and carbon measurement, and the calculator can complement a carbon footprint analysis.

PVC ball valve

Assured Automation has extended its Ball Valve Line with the addition of the P2 Series full port PVC true union ball valve. A data sheet and tech specs on the series is available on the company's website. Available in ½" to 4" the series offers a variety of advanced features such as a high quality stem and ball support system and a multifunctional locking handle. In addition, the series' Dual Block® system locks the union nuts preventing back-off due to vibration or thermal cycling. Deep grooves, thick o-rings and cushioned PFA seats contribute to strong seals at pressures up to 232 PSI while an integral mounting flange and support bracketing combine for a simple adaptation for actuation and anchoring.

Flow, level products

Greyline's flow and level product brochure features non-contacting instruments for closed pipe flow. Both portable and permanently installed Doppler flow meters or flow switches measure flow from outside a pipe. They are ideal for raw sewage, sludge, treated effluent, slurries and viscous liquids. The company's open channel flow systems can be calibrated to any flume or weir. The OCF 5.0 Open Channel Flow Meter monitors, displays, transmits and data logs wastewater flow. Non-contacting level systems include the new SLT 5.0 Level & Flow Monitor to monitor, transmit and control level in sumps, lift stations, chemical storage tanks, or for open channel flow applications.

Bearing fault frequencies

Ludeca has created normalized bearing information that contains approximated bearing fault frequencies without the need to know the manufacturer and other difficult to obtain bearing information. The data is available for download at This information allows the analyst to correlate vibration data to specific components in the equipment that may be in some stage of failure. Correctly addressing these failure conditions will increase equipment reliability resulting in greater uptime, increased capacity, improved product quality, better safety, lower costs, and reduced risks.
