Water Quality Meters Monitor Water Resources
These compact water quality test meters measure and monitor factors essential to sustaining vibrant ecosystems, preserving public safety, and responsibly managing water resources. The suite includes the EC210 conductivity/TDS (total-dissolved-solids) meter, the PH210 pH/ORP/temperature (oxidation-reduction potential) meter, and the DO210 dissolved oxygen (DO) meter. The instruments feature a large dual-reading display that indicates the relevant reading and the water temperature. Because water temperature affects many water quality factors, automatic temperature compensation (ATC) adjusts the reading relative to the temperature. The EC210 helps to determine water purity using conductivity to identify the presence of dissolved solids, which can help predict changes in a water system. In addition to pH, the PH210 provides ORP measurements, which help to quantify the ability of water to break down contaminants. Because high DO levels can accelerate corrosion, the DO210 monitors DO to ensure the integrity of water pipes and boilers.

Software Utility Reduces Brittle Fracture Risk
Rapid depressurizing and gas expansion can create very low temperatures that put equipment at risk of brittle fracture. Understanding depressurizing behavior in blowdown systems is critical to the functionality as well as the safety of a facility and its employees. The Design Blowdown Utility is an enhancement to the UniSim design and simulation software that assists in designing systems for safe depressurization of equipment. It offers companies a more-accurate method for selecting construction materials and blowdown system sizes to help manage capital costs. For new equipment, an accurate estimate of the minimum vessel wall temperature during blowdown is critical for selecting construction material and avoiding overdesign that unnecessarily increases project costs. For an existing facility, a blowdown study can guide changes to operating procedures, equipment materials, or capacities to reduce brittle fracture risk.
