Sherwin-Williams has introduced a fast drying, low viscosity polyurea primer for steel and concrete that can be applied in temperatures as low as 0° F. Envirolastic® LT Primer is a reliable year-round product, ideal for low temperature applications or whenever a fast dry/fast recoat primer is required. At 77° F, surfaces can be recoated after one hour; at 40° F, surfaces can be recoated after five hours. When properly applied, the fast-drying primer reduces the likelihood of pinholes or holidays in the coating film caused by outgassing from the concrete substrate.

Water analysis system
The new FlowCAM® -XPL Birefringence Imaging and Analysis System from Fluid Imaging Technologies automatically detects and documents the presence or confirms the absence of invasive mussels in a water sample. Ideal for the early detection of zebra mussels, quagga mussels and other aquatic invasive species, the instrumentation features cross-polarizing filters that reveal individual mussel cells at the larval veliger stage when they measure a mere 50-250 um to permit treatment before their growth and entrenchment makes eradication virtually impossible.

Wide area network
Aclara has introduced a mesh-based wide-area network for utilities. The Aclara Smart Communications Network is a high-bandwidth, standards-based, broadband solution that will bring together existing utility assets and applications into a single network. The network is designed for use by water, gas or electric utilities and employs TCP/IP communications protocols as well as IEEE 802.11 standards for wireless communications. It allows utilities to replace multiple, low-to-medium bandwidth systems that now communicate data to utilities. The system provides an interface to utility and IT resources and back-office applications for SCADA control and monitoring systems, advanced metering infrastructure (AMI), home-area networks, and mobile-workforce applications.

Graphite Metallizing Corp. has developed several bronze Graphalloy® grades that do not contain lead. These essentially lead-free formulations are used in bearings and bushings where the potential for lead contamination is unacceptable. Applications include deep-well and potable water pumps. The no-lead bronze has been accepted by the FDA as suitable for many food-grade applications. The bushings and bearings are non-galling and are dimensionally stable even when submerged, under load or experiencing wide temperature swings. Because the bushings and bearings are self-lubricating, they are suitable for applications where maintenance operations are infrequent or difficult.

Power management software
Schneider Electric has announced the release of major enhancements to PowerLogic™ ION Enterprise™ Software, its power management software package. The product offers metering and protection, with extensive capabilities via a new Web Reporter module, making it easy for the user to create, customize and schedule reports. The software tracks real-time power conditions, analyzes power quality and reliability, and responds quickly to alarms to avoid critical situations. A vital part of this application is the data gathering network, which recently expanded to include the Sepam series of protective relays. The software delivers energy usage and power quality information exactly when, where and how the user needs it. New reporting functions include period-over-period or by-shift comparisons, trending and tables, alarm and events history, and system configuration.

Interface level measurement
Hawk "ORCA" Sonar Bed Level Transmitters can be used to control compact bed level and maximize the performance of thickeners and clarifiers. By monitoring two independent interface densities the transmitters are able to provide reliable process feedback for the control of the underflow pump to optimize the underflow density. It removes operators from manually controlling underflow pumps based on rake torque and bed pressure which are greatly affected by density change. It also allows operations to run thickeners at manufacturer's optimum design levels with less risk of rake overload.
