Chem-Feed C-1500N diaphragm metering injector pumps have a permanently lubricated gear motor for smooth, quiet performance. The valve body and fittings are constructed of chemical resistant PVDF. Valves have FKM static seals and TFE/P ball seat O-rings. The diaphragm is made of PTFE-coated EP. The design allows for a minimum stroke length of 5%. Time is adjustable from 5% to 100% of the repeating 5-second time interval, which results in precise, high-frequency injections. The pump is NSF, ETL, CSA and CE listed.
FCL Series sensors use amperometric measurement technology to provide accurate monitoring of free chlorine in process applications. The sensors are compliant with U.S. EPA method 334.0 for measuring drinking water. Models are available to cover 0- to 2-ppm, 0- to 5-ppm and 0- to 10-ppm ranges. The sensors’ membrane design features a mesh reinforcement clamp for stability and durability. The integral 4-20 mA isolated signal output is enhanced to eliminate ground loop errors, reduce noise and block high-voltage transient surges.
The Halo refillable glass pH probe comes with Bluetooth technology, allowing it to transmit measurement data directly to an iPad with its accompanying Hanna Lab App. This free application turns an iPad into a full-featured pH meter when paired with the wireless probe.
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.
