Flow, Level, Temperature Switch
The FlexSwitch® FLT93S flow–level–temperature switch performs monitoring, controlling, and alarming of flow rates or levels of critical fluids. The switch is a dual-function insertion-style instrument that offers either flow–temperature sensing or level–temperature sensing. With a thermal dispersion mass flow sensor, the system features built-in temperature compensation for operation in extreme environments. The FLT Switch operates over a setpoint range in water from 0.003 to 0.9 m/s (0.01 to 3.0 ft/s). The standard FLT93S withstands operating temperatures from –40°C to 177°C (–40°F to 350°F).

Software
The VUEWorks® 2009 scalable suite of software modules for managing work processes, capturing citizen concerns, and executing preventive maintenance enables companies and organizations to track the condition, minimize the risk of failure, prioritize expenditures, and manage service delivery of their physical assets. It enables organizations to retrieve key asset data, apply work-management practices, and develop strategic asset management programs for any infrastructure physical asset. A new Facilities Module provides flexible tracking of any asset that is typically not identified as part of the geographical information system (GIS) data. Facilities can be linked to GIS assets for easy selection from the map. Individual assets — such as pumps, motors, valves, switches, and controls — can include values for condition, valuation, and work history. Users also can create multiyear budget scenarios based on deterioration curves and automatically trigger different types of repair options, based on where the segment falls on the deterioration curve. VUEWorks Inc. (Concord, N.H.).

Designed to work with RS Technical Omni III, NovaSTAR, and TrakSTAR cameras, it provides inspection capability in sanitary or storm lines 6 to 30 in. in diameter and up to 3000 ft in length. The TranStar can turn on its own axis and travel up to 60 ft/min with three forward speeds, reverse, and freewheel. RS Technical Services Inc. (Petaluma Calif.).

Imaging Sonar
The Gemini 720i multibeam imaging sonar is designed to combine the benefits of long-range detection with high-definition imaging techniques. With a lightweight, compact design, the sonar can be deployed on most Remotely Operated Vehicle and Autonomous Underwater Vehicle platforms. Weighing 1.2 kg in water, Gemini is supplied with Ethernet and very-high-bit-rate digital subscriber line communication modes, which offer the option to communicate either through fiber-optic cables or long-distance twisted-pair channels, depending on the configuration of the umbilical. The introduction of a curved transmit transducer array ensures that acoustic energy power is evenly transferred across a wide-swath imaging sector, speeding up search and navigation operations. To sharpen up the acoustic range resolution, an innovative sound-velocity sensor has been integrated into the design to monitor the local velocity of sound conditions. Tritech International Ltd. (Aberdeen, Scotland).

Piston Pumps
The H25 and H38 Advanced™ series metal piston pumps have been designed for use in applications with low volumes and high discharge pressures. The H25 pump utilizes a simplex-action piston to create approximately a 13:1 pressure ratio of discharge fluid to inlet air supply to generate up to 110.3 bar (1600 psig). The H38 model uses a double-action piston to create a 26:1 pressure ratio of discharge fluid pressure to inlet air supply to generate up to 220.6 bar (3200 psig). The pumps are designed for applications that require discharge pressures greater than the 1:1 pressure ratio. The maximum flow rate for the H25 is 4.1 L/min (1.1 gal/min) and the maximum flow rate for the H38 is 7.6 L/min (2 gal/min), with a maximum inlet air pressure of 8.6 bar (125 psig).
