Pennwell web 200 160

The Model ML04 Water Specialties Propeller Flow Meter™ from McCrometer is available with an optional transmitter that provides a 4-20 mA output, which indicates either flow rate or totalized flow volume in support of Supervisory Control and Data Acquisition (SCADA) Systems. The steel flanged-end tube meter has an indicator-totalizer. It features measurement accuracy of ±2 percent, and can be used to measure liquid flow from 40 to 35,000 gpm, depending on line size. The meter is suitable for service in line sizes from 2” to 48” and is designed for temperatures up to 140°F. McCrometer, Hemet, CA, 800-220-2279, www.mccrometer.com

The GF90 Mass Flow Meter from Fluid Components International offers improved performance in gas measurement applications, such as chlorinated water disinfection systems, with less maintenance, and lower installation and operating costs. The mass gas flow meter is inserted in chlorine gas process piping, and its 4-20 mA output wired to the input/output (I/O) modules in an automation system. The automation system then continuously measures and controls the amount of chlorine to be dispensed for optimum water purity.
