Ensure System Safety and Reliability with NNT's NPF3W7 Water Flow Meter

In cooling systems, medical equipment, and water treatment applications, consistent and reliable fluid flow is critical. A sudden loss of flow can lead to equipment overheating, process failure, or severe damage. The NNT NPF3W7 Water Flow meter is your essential safeguard, providing immediate detection of flow presence or absence to protect valuable assets.

• Accurate & Reliable Detection: The sensitive paddle mechanism instantly responds to water flow, sending a clear electrical signal to your PLC or alarm system to trigger corrective actions.

• Robust & Durable Construction: Featuring a brass body and IP65 protection rating, the meter is built to withstand humid, demanding industrial environments, ensuring long-term performance.

• Easy Installation & Adjustment: With simple in-line installation and an adjustable sensitivity setting (for specific models), the NPF3W7 can be finely tuned to match your system's required flow rate threshold.

• Clear Visual Status: A built-in LED indicator provides immediate local visual confirmation of the flow status (flow/no-flow), simplifying maintenance and troubleshooting.

• Cooling & HVAC Systems: Protect chillers, laser cutters, and injection molding machines from dry running due to pump failure or clogged filters.

• Medical & Laboratory Equipment: Ensure safe operation of autoclaves, analyzers, and other devices dependent on coolant or process water flow.

• Water Treatment & Pumps: Monitor pump performance and activate alarms for low-flow conditions in filtration or circulation systems.

• Industrial Machinery: Provide flow confirmation in lubrication, cooling, or washing processes across manufacturing lines.
