Chemical Injection for Water Treatment
Direct mass flow measurement with Coriolis meters reduces cost to meet water quality requirements
Control of high-cost additives optimizes chemical usage
Water treatment facilities require multiple steps to receive, disinfect, and ultimately convert raw water to a final product. The treatment process starts with chemicals being applied to raw water as a clumping agent to pull dirt and particulates into filters. Later in the process there are additional dosing applications including chemicals such as pre- and post-caustic, polymer, and polyphosphate, and gases such as chlorine and ammonia. These additives can be expensive and/or highly corrosive, so having precise measurement and control of quantity and quality throughout the process is critical. Too much additive can be costly, but too little introduces the risk of inaccurate dosing or undesired reaction, causing issues throughout the remaining water treatment cycle. The highly accurate and direct mass flow and density measurements provided by Micro Motion ELITE™ Coriolis Flow Meters ensure chemical dosing is paced accurately to the raw water even when flow rate is constantly changing.

Product Solutions
The 4200 2-wire Coriolis meter lowers capital expenditures and provides a faster commissioning time with the ability to share power and signal over the same pair of wires reducing installation, engineering, and planning costs. The 2-wire Coriolis meter does not require any straight runs or flow conditioning providing a robust, repeatable, and reliable solution with no moving parts, and wide turndown, improving product quality leading to less rework and waste.
- Available with a wide range of Coriolis mass flow sensors with up to +/-0.10% mass flow accuracy and +/0.0005 g/cc density accuracy for liquids and slurries or +/-0.25% mass flow accuracy for gases.
- The integrated real-time clock time stamps process data, alerts, Smart Meter Verification reports and audit logs. Data Historian on board offers a complete audit trail to determine process issues.
- Graphic display that supports 8 languages and can be rotated using the integrated software rotation without removing the front cover, thereby minimizing downtime due to hot work permit restrictions.
