Wallace & Tiernan NPXB-143 Industrial Flow Meter

Description:

The Wallace & Tiernan NPXB-143 Flow Meter is an industrial variable-area flow meter designed for measuring and monitoring low-flow water applications in water treatment, chemical dosing, chlorination, filtration, and process control systems. Commonly installed in municipal water facilities, wastewater treatment plants, chemical feed skids, and industrial process systems. Maintenance technicians, plant operators, and process engineers use this flow meter to verify flow rates, maintain dosing accuracy, and ensure reliable operation of treatment and process equipment.

Applications:

The Wallace & Tiernan NPXB-143 flow meter is designed for low-flow liquid monitoring applications requiring accurate measurement, dependable operation, and long-term reliability. It is frequently utilized in potable water treatment plants, wastewater processing facilities, chlorine feed systems, chemical injection equipment, industrial process water applications, and automation control environments where precise flow regulation, process efficiency, and regulatory compliance are critical. The low-capacity design makes it particularly suitable for metering chemical additives, treatment solutions, and water flow in process control loops.
