GF 3-2819-S1 Signet Conductivity Sensor compact PTFE Diaphragm Petrochem

Product Specification

​1. Product Overview: GF 3-2819-S1 Compact Flow Sensor

​
The GF 3-2819-S1 is a precision-engineered flow sensor designed for real-time monitoring and control of liquid media in industrial automation systems. Manufactured by GF Piping Systems, this compact sensor utilizes advanced ultrasonic or electromagnetic measurement technology to deliver accurate flow rate data for water, chemicals, and other non-aggressive fluids. Housed in a corrosion-resistant polymer or stainless steel casing (IP65/IP67-rated), it withstands harsh environments, including exposure to humidity, temperature fluctuations (-20°C to +80°C), and mild chemical vapors. The sensor’s modular design allows easy integration into pipelines, HVAC systems, and process control networks, making it ideal for water treatment, food and beverage production, and pharmaceutical manufacturing.

​2. Key Technical Specifications​

• ​Measurement Range: 0.1–50 L/min (adjustable based on pipe diameter).
• ​Accuracy: ±1% of reading (±0.5% with calibration).
• ​Output Signals: 4–20 mA analog, pulse, or Modbus RTU.
• ​Pressure Rating: Up to 16 bar (232 psi).
• ​Operating Temperature: -20°C to +80°C.
• ​Material Compatibility: PP, PVDF, or 316L stainless steel.
• ​Power Supply: 12–30V DC (low power consumption ≤5 W).
• ​Certifications: CE, RoHS, ISO 9001.
• ​Response Time: ≤1 second.

​3. Industrial Applications and Use Cases

​
The 3-2819-S1 is widely used in water treatment plants to monitor filtration and dosing processes, ensuring optimal chemical injection rates. In HVAC systems, it tracks coolant flow to maintain energy efficiency and prevent pump cavitation. 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. Additionally, it supports leak detection in irrigation systems and flow verification in fire suppression networks. Its chemical-resistant materials make it suitable for corrosive media in chemical processing and semiconductor manufacturing.

​4. Competitive Advantages and Unique Features​

• ​High Accuracy: Calibrated to ISO standards for repeatable measurements.
• ​Durability: Corrosion-resistant materials ensure longevity in aggressive environments.
• ​Versatile Outputs: Supports analog, digital, and bus communication for flexible integration.
• ​Low Maintenance: Non-intrusive design eliminates wear from moving parts.
• ​Easy Installation: Compact size and standardized fittings (e.g., G¾, NPT) reduce setup time.

​5. Functional Capabilities and Operational Benefits

​
The 3-2819-S1 provides real-time flow data to PLCs or SCADA systems, enabling automated adjustments to pumps and valves for process optimization. Its fast response time detects sudden flow changes, triggering alarms for leaks or blockages. The sensor’s low power consumption and rugged design minimize downtime and operational costs. By ensuring precise flow control, it enhances product quality in batch processes and reduces waste in water-intensive industries. Compliance with CE and RoHS standards guarantees safety and environmental compliance, making it a sustainable choice for modern industrial automation.
