​1. Product Overview: GF d32 Compact Flow Sensor

​
The GF d32 is a precision-engineered flow sensor designed for accurate liquid flow measurement in industrial automation and process control systems. Part of GF Piping Systems' renowned product line, this sensor employs ultrasonic or electromagnetic technology to monitor flow rates in real time, ensuring optimal performance in water treatment, chemical processing, and HVAC applications. Constructed with a robust PVC-U or stainless steel housing (IP65/IP67-rated), it resists corrosion, high pressures (up to 16 bar), and temperature extremes (-20°C to +60°C). The GF d32 features modular connectivity, supporting analog (4–20 mA) and digital (Modbus RTU) outputs for seamless integration into PLCs and SCADA systems, making it ideal for industries demanding reliability and precision.

​2. Key Technical Specifications​

• ​Response Time: ≤1 second.

​3. Industrial Applications and Use Cases

​
The GF d32 is widely used in water treatment plants to monitor filtration efficiency and chemical dosing processes. In HVAC systems, it ensures balanced coolant distribution to prevent energy waste and equipment damage. Food and beverage manufacturers deploy it for hygienic flow control in CIP (Clean-in-Place) systems, while pharmaceutical facilities rely on its accuracy for batch processing of sensitive liquids. Chemical plants use the stainless steel variant to handle corrosive fluids like acids and solvents. Additionally, it supports leak detection in irrigation systems and flow verification in fire suppression networks, offering versatility across multiple sectors.

​4. Competitive Advantages and Unique Features​

• ​High Precision: Calibrated to ISO standards for repeatable, reliable measurements.
• ​Corrosion Resistance: Suitable for aggressive media, extending service life in harsh environments.
• ​Flexible Connectivity: Dual analog and digital outputs enable compatibility with legacy and modern control systems.
• ​Low Maintenance: Non-intrusive design eliminates wear from moving parts.
• ​Easy Installation: Standardized G¾ or NPT fittings simplify retrofitting into existing pipelines.

​5. Functional Capabilities and Operational Benefits

​
The GF d32 delivers real-time flow data to automate pump and valve adjustments, optimizing process efficiency and reducing energy consumption. Its rapid response time detects sudden flow changes, triggering alarms for leaks or blockages to prevent downtime. The sensor’s low power design and IP67 rating ensure reliable operation in remote or hazardous locations. Compliance with WRAS and CE standards guarantees safe use in potable water systems, while Modbus RTU connectivity supports Industry 4.0 initiatives for predictive maintenance. By minimizing waste and enhancing process control, the GF d32 lowers operational costs and supports sustainable industrial practices.
