Tadiran Batteries has introduced an improved version of its PulsesPlusTM battery that allows for an indication at end-of-life, allowing end users to maximize the service life of the battery. In some cases, batteries are replaced prematurely based on estimates of remaining battery life. Tadiran offers a 3.6v system with a 5% end-of-life indication (when the battery uses up 95% of its capacity, a remote indicator can advise the end users that 5% of operating life remains.)

Metering management

The Tantalus Utility Network - TUNet - is a two-way, real-time data communications network designed for water, electric and gas utilities. The end-to-end system supports multiple commodities, applications, and OEM metering products. A common network for all commodities helps utilities contain costs and mitigate risk. Utilities share the infrastructure, but can deploy the network and applications to as few or as many consumers as they desire, and in whatever order best fits the business plan.

The Fluoride Safety Sentinel 21 is the first fully automated Modular Fluoridation System manufactured to safely and efficiently inject fluorosilicic acid into the Public Water Supply. Designed as a closed-loop system, the need for operating personnel to estimate daily flow rates, coupled with the possibility of human error, is eliminated. The standalone system instantaneously adjusts chemical feed rates with each change in supply flow rate or fluorosilicic acid concentrations.

US EPA amended the Code of Federal Regulations (40 CFR Part 136) on March 12 to provide full approval for a new method: “Digestion and Distillation of Total Cyanide in Drinking and Wastewaters using MICRODIST® and Determination of Cyanide by Flow Injection Analysis,” also referred to as QuikChem® Method number 10-204-00-1-X by Lachat Instruments. The MICRODIST system quantitatively scales down the sample and reagent volumes like those required by macro-distillation in EPA methods. The batch micro-distillation system uses sample volumes of less than 10 mL.

The Larox Flowsys new 3" LPP produces the highest flow per compression of any hose pump. In almost all cases a one size smaller pump can be used compared to a shoe design or double compression design peristaltic pump. The company has developed the first significant design change in industrial peristaltic pumps in many years. The LPP family of pumps has a 360 degree elliptical rolling design which creates virtually no heat, has lower hose stress, and offers lower energy consumption and longer hose life.
