Emerson Process Management has introduced a family of more than 50 Device Dashboards for its AMS®
Weigh batch eductor
A new Bulk Bag Weigh Batch Eductor System from Flexicon loosens bulk solid material that has solidified during storage and shipment, discharges the material by weight, and blends it into a liquid stream. The skid-mounted system incorporates two Bulk Bag Unloading Frames, each with an integral Bulk Bag Conditioner comprised of a hydraulic pump and two rams with contoured end plates that press opposing sides of bulk bags.

The Hydrovar Variable Speed Controller from ITT Goulds Pumps can improve the energy efficiency of centrifugal pumps. The controller is an update to the Aquavar motor-mount drive series with a new modular design and more intuitive programming for setup and troubleshooting. When mounted on inline or end-suction centrifugal pumps, it maintains proper system pressures and flows by controlling the speed of the pump, producing energy savings of up to 70 percent compared to fixed-speed pumps.

Mass flow meter
The new Model ST51 Mass Flow Meter from Fluid Components International is designed as an application-specific solution for monitoring digester gas, biogas and other methane composition biofuel gases as well as natural gas. The company calibrates the meters in its NIST-traceable flow lab to match the gas composition and specific flow conditions of the user’s digester system, which results in an instrument that is matched precisely to the facility’s actual operating environment.

The AquaExcel® Batch Reactor process is an ideal application for municipalities and industries which are sensitive to odor considerations. While such systems can produce a light, musty scent, it is normally not considered objectionable and is typically limited to the direct vicinity of the water surface. The system can easily be covered, if desired, with the exhaust gas available for venting, or further treatment if preferred. The batch reactor incorporates benefits of the AquaSBR® system with advanced decanting and process monitoring and control.

Kaeser’s new HSD system features two independently operating compressors in a single enclosure. These new packages are available from 500-650 hp, and deliver flows from 1632-3002 cfm and pressures from 100-217 psig. The system incorporates two individual compressor units including a motor, Sigma Profile airend, separator aftercooler, draintrap and filtration. Because each module is a complete compressor – and not just two airends stacked together – the HSD provides maximum part-load efficiency, built-in redundancy, and reduced installation costs. The compressor units are started one after another to reduce inrush current and protect against network overload. Kaeser Compressors, 800-777-7873, www.kaeser.com/sigma
Ashcroft® A-Series pressure switches are designed for tough OEM and industrial applications requiring a miniature switch. Available with explosion-proof and watertight enclosures, the stainless steel A-Series pressure switch features a refined piston actuator that can be ranged up to 2000 psi while enduring a working pressure of 5000 psi. Small dimensions, a choice of connections and a field adjustable set point make the pressure switch easy to configure and install in nearly any alarm, shutdown or control application.
