AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
Metal-free flowmeters are well suited for ultrapure water, deionized water and highly corrosive applications. The float is guided by polysulfone ridges that are molded into the meter body. Floats are constructed of PTFE, allowing no metal contaminants into the fluid path. Adapters are constructed of polysulfone, PVC or PVDF, depending on model; and O-ring seals are FKM (EP is optional). Optional socket-fusion 63-mm fittings also are offered.
The Sonic-Pro S4 inline ultrasonic flowmeter measures flow using the Transit Time method. The technology has no moving parts and no internal liners. Pipe fittings facilitate installation of the meter, and a special low power mode permits operation with battery for limited functions. Download data logging files directly to a flash drive via USB. The flowmeter is NSF 61 certified and the housing is NEMA 4X/IP 66 for wash-down.
The WM-LF lead-free bronze water meter works under a wide flow range and can tolerate low-quality water. The NPT male connection makes it easy to fit into standard piping. The magnetic drive eliminates potential leak point and the low flow indicator shows flow rates down to almost drop-by-drop. The meter can be used in residential and commercial systems for metering and sub-metering, and in industrial food and beverage, plant process water, cement mixers and pond water feed lines.
Sonic-Pro Hybrid Ultrasonic flowmeters are available with the T-Track mounting system and feature NEMA 4X quick disconnects. They use Doppler or Transit Time for measurement, and work with clean and dirty fluids. Features include custom quality metric algorithms and DSP technology; easy-read display; standard SD card format data logging; isolated 4-20 mA output; and 0- to 1,000-Hz pulse output. Computer connection permits remote access and control of all functions.
Fluidics Hawaii’s device meets NSF and California building code standards
NSF Intl. has certified the first flowmeter for pool, spa and water park applications to the American National Standard for recreational water equipment and the new California regulations. Fluidics Hawaii LLC’s FV-C mechanical flowmeter is the first to earn NSF certification to this standard, demonstrating to pool operators and regulators its ability to effectively and accurately measure water flow. This is critical to disinfection, filtration and maintaining safe water circulation rates.
The Model 1801 pump control is a simple, logical safety device, specifically designed and developed for the water treatment industry. It is used in conjunction with chemical feed pumps to turn on when sufficient water is present. This unit is a pre-wired, self-contained flow switch and feed pump control.
Designed for 1-, 1½- and 2-in. pipe systems, FSI-T00 flow sensors are constructed with a high-density polyethylene impeller, Type 1 PVC sensor housing, tungsten carbide impeller shaft and BUNA-N O-ring. They are suited for water treatment systems, water dispensing, cooling loops, irrigation systems, large-scale aquariums and more. They feature a molded mounting tee that provides improved control of dimensions for consistent measurement and improved performance at low flow rates. For easy servicing, they feature a threaded retaining nut instead of a retaining pin.
