The new Ashcroft® XmitrTM combines advantages of the PowerFlexTM pressure gauge with transducer technology to create a single, convenient, dual-function instrument. With half the number of instruments to install, it saves instrumentation and installation costs, time, and space. It provides traditional transducer features including 4-20mA and voltage outputs, CE ratings and 1% BFSL accuracy with electronic temperature compensation from -20°C to 85°C.

The new-generation Regal SmartValveTM is a flow pacing valve that uses advanced electronics − including a bright, easy-to-read Polymer LED display. These units can feed chlorine, sulfur dioxide or ammonia gas. The valve can be configured to operate in either flow proportional or step-rate control modes. And it can be operated in the field four ways - fully automatic, electric/manual, and two methods of manual. Chlorinators Inc., Stuart, FL, 800-327-9761,

Flow transmitter

SonicSolutions®, which uses resonance of the ultrasonic waves to kill algae, offers an environmentally safe way to control algae. It’s safe for fish, plants and other aquatic life and uses just 20-45 watts of power. Floating just below the surface, the system operates 24-hours a day providing coverage for up to 3 acres depending on conditions. EPA-registered, it uses no toxic chemicals and requires minimal maintenance. It’s proven effective in ponds, lakes, reservoirs and tanks, and is currently used at water and wastewater plants, power plants, golf courses, botanical gardens, and in irrigation systems.

Liqui-Flux® ultrafiltration modules incorporate a hydrophilic polyethersulfone (PES) hollow fiber membrane with an inner diameter of 0.8 mm and a MWCO of 80 kDa. The distinctive three-layer membrane combines critical tasks of sustained mechanical strength and excellent flux rate with high removal efficiencies. When tested side-by-side with three competitive filtration devices, these UF modules used less than half the energy to deliver the same performance. With an outer surface and inner support layer, Membrana’s Performance Enhancing Technology (P.E.T.®) provides further strength and consistent membrane distribution by intertwining additional filaments around the hollow fibers within the bundles - offering 657 sq ft of effective filtration area.

Added to Hach’s growing family of compatible digital sensors, the sc100 Controller accepts any two sensors - in mix-or-match arrangement - from Hach digital sensors now available, including for pH, ORP, conductivity, dissolved oxygen and turbidity - to best target measurement at aeration tanks, nitrification and denitrification tanks, anaerobic digesters, aerobic digesters and treatment discharge. Each sensor is designed for simple ‘plug and play,’ ready for deployment without special cabling, configuration or software. The Hach Company, Loveland, CO, 800-227-4224,

Tablet degreaser

Using Cellinite BioTabsTM can help reduce costs and odors associated with grease control and grease trap maintenance in food processing facilities. Cellinite Technologies’ tablet wastewater treatment system cuts grease solids and eliminates grease caps that can form in grease traps and collection systems. The tablet uses its density to sink to the bottom of the wastewater where a patented oxygen-delivery system to super-oxygenates the wastewater. pH buffers, nutrients and aerobic bacterial spores are distributed through out the tank by an oxygen plume from the effervescing tablet - creating an ideal environment for the aerobic bacteria to start degrading the grease solids, grease cap and other sediments. Cellinite Technologies, Needham, MA, 781-453-2233,
