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.
The device uses sound waves to measure water levels
Imagine turning on your faucet only to find there is no water flowing. Your well has run dry, and you have to pay tens of thousands of dollars to fix it. That is the scary scenario for communities grappling with drought, and it is a potential danger for the 43 million Americans nationwide (15% of the population) on well water.
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.
MJ-SDC multi-jet water meters are available for ¾- to 2-in. pipe sizes. They are dry dial-type totalizing water meters, offered with pulse switch outputs of one pulse per 0.1, 1, 10 or 100 gal. A 59-in. length of two-conductor wire, 3.5-mm diameter, is standard. The main casing is made of ECO brass, and the maximum operating temperature and pressure are 122°F and 150 psi, respectively. The meters comply with NSF/ANSI standards 61 and 372, and conform with lead-free plumbing regulations.
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.
ITS will give away one eXact iDip smart photometer system every Friday until Sept. 19
Industrial Test Systems Inc. (ITS) announced its 2014 eXact iDip Summer Giveaway. Beginning June 20, the company will give away one eXact iDip smart photometer system to a lucky participant every Friday until Sept. 19. This new smart photometer system is waterproof and features two-way wireless communication with a smart device. The app comes with four tests installed and more than 30 additional tests available for download.
The eXact Micro 20 dual-wavelength photometer uses narrow-band wavelength filters for enhanced, accurate results. It features stable LED light sources and a built-in cell that uses a simple patented system for colorimetric analysis. All tests are designed to use an identical 20-second procedure to increase ease of use.
The YSI Pro1030 handheld meter measures pH or ORP, plus temperature, conductivity, specific conductance, salinity and TDS. It has user-replaceable pH and ORP sensors, cables and a convenient calibration. Its ruggedness is backed up by military-spec connectors, IP67 waterproof and rubber over-molded case, and 1-meter drop tests. A four-electrode conductivity cell is built into the cable and requires minimal maintenance.
The Q-16 flow switch uses a patented elastomeric sealing system that resists the metal fatigue and corrosion associated with metal bellows. It can be used in pipes 1 in. or larger, with set points from 4 to 500 gpm. It uses a 15 A micro switch that can control a 0.5-hp motor.
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.
