Operating Principle of Dwyer PFT-HAN-B611-S Paddlewheel Flow Sensor

The Dwyer PFT-HAN-B611-S operates using a paddlewheel mechanism, where a small rotor rotates within the water flow. The rotation generates a pulse signal proportional to flow velocity, which can be sent to PLCs, HVAC controllers, or BMS systems for monitoring and control.

The sensor’s non-contact electrical design and corrosion-resistant wetted materials allow reliable operation in clean water, treated water, or wastewater systems. Its high sensitivity ensures detection of very low flow velocities, providing accurate monitoring for both protection and process control.

Practical Applications Across Industries

In commercial HVAC systems, the Dwyer PFT-HAN-B611-S Paddlewheel Flow Sensor monitors water velocity in chilled and hot water loops to ensure pumps operate at optimal conditions. Integrated with BMS, it prevents pump overrun or dry running, protecting equipment and improving energy efficiency.

In water treatment and wastewater facilities, the sensor provides real-time flow velocity monitoring in pipelines. Operators can use the data to adjust valves, pumps, and flow splitting for efficient system operation.

In food and pharmaceutical processing, controlling water velocity is critical for cooling and transporting liquids. The Dwyer PFT-HAN-B611-S Paddlewheel Flow Sensor delivers precise pulse signals for automation systems, ensuring consistent product quality.

In industrial machinery and equipment cooling systems, the sensor monitors flow velocity to prevent overheating. When flow falls below a set threshold, alerts or automatic shutdown can be triggered to protect equipment.

Benefits of Using Dwyer PFT-HAN-B611-S Paddlewheel Flow Sensor

The Dwyer PFT-HAN-B611-S Paddlewheel Flow Sensor offers several practical benefits. Its paddlewheel design ensures stable operation, high accuracy, and low maintenance. Wetted parts are made from corrosion-resistant engineering plastics, suitable for clean or treated water.

The pulse output, proportional to flow velocity, can be integrated directly with PLC, HVAC/BMS controllers, or SCADA systems, enabling efficient monitoring and control. The sensor’s ABS/PVC housing withstands moisture and environmental exposure, allowing both indoor and field installation.

Key Technical Specifications

Selecting the Right Model

When choosing the Dwyer PFT-HAN-B611-S Paddlewheel Flow Sensor, consider pipe diameter, flow velocity range, and output signal type. The sensor can be installed inline without disrupting flow, providing accurate monitoring.

For applications requiring continuous analog flow measurement, a pulse-to-analog converter can be used. However, for flow velocity monitoring and equipment protection, the PFT-HAN-B611-S is a reliable and easy-to-integrate solution.
