1. Flow Transmitter: The Intelligent Data Processing Center

To convert raw sensor data into real operational actions, the sensor must be connected to a central controller, typically the AM-2250 series.

The AM-2250 display functions as an intelligent control hub. It not only shows real-time values with high resolution, but also allows operators to configure advanced set-points. When the flow rate moves outside the safe range, the controller instantly processes the data and sends a 4–20mA analog signal to the dosing pump for immediate dosage adjustment. This combination creates a closed-loop control system, ensuring that flow is always maintained at the ideal level—preventing underdosing that may lead to contamination, or overdosing that causes waste and equipment corrosion.

2. Compatible Sensors and Operating Efficiency

To achieve the highest measurement accuracy, sensor selection should be based on the physical and chemical properties of the liquid as well as the actual installation conditions.

A. Paddlewheel Sensors – Series 515 and 2536

This is the most common solution for clean liquids or liquids containing only a small amount of debris.

• Technical specifications: Manufactured from high-quality plastic materials (CPVC, PVDF, PP) or stainless steel. Measuring range from 0.1 m/s to 6 m/s.
• Efficiency: High durability, low cost, and easy maintenance thanks to the retractable design, which does not require cutting the pipeline.

B. Magnetic Flow Sensors (Magmeters) – Series 2551 and 2552

An optimal solution for conductive liquids, wastewater, or highly corrosive chemicals.

• Technical specifications: Operates based on the principle of electromagnetic induction, with no moving parts. Wide measuring range from 0.05 m/s to 10 m/s.
• Efficiency: Eliminates pressure loss in the pipeline and minimizes maintenance costs due to the absence of mechanical friction.

C. Variable Area Sensors

Suitable for applications that require direct visual monitoring without the need for electrical power.

• Mechanism: Flow is observed visually through the position of the float inside a transparent plastic tube.
• Efficiency: Can be equipped with a magnetic switch to send high/low alarm signals to the controller.

D. Ultrasonic Sensors

 

A non-intrusive measurement solution, ideal for system upgrades where pipe cutting is not desired.

• Specifications: Clamp-on type, compatible with many pipe materials.
• Efficiency: Fully hygienic for pharmaceutical and food applications because it does not come into direct contact with the liquid.

3. Outstanding Benefits of a Synchronized Solution

Investing in a dedicated flow measurement system brings long-term operational and economic value:

• Perfect compatibility: Using devices within the GF+ ecosystem eliminates signal mismatch errors between the sensor and the display unit.
• Superior chemical resistance: Polymer-based measuring devices perform reliably in acidic and highly alkaline environments, where metal devices are often prone to oxidation.
• Cost optimization: Accurate flow control improves pump regulation and prevents unnecessary consumption of raw materials.

4. Practical Applications

GF+ flow measurement solutions are widely used across many key industries:

• Water & wastewater treatment: Monitoring total inflow and outflow.
• Chemical manufacturing: Accurate measurement of highly corrosive media in production lines.
• Food & Beverage (F&B): Ensuring hygiene and precision in filling and dosing processes.
• HVAC systems: Monitoring chilled water flow to optimize energy performance.

Conclusion

The combination of GF+ flow transmitters and flow sensors delivers not only high measurement accuracy, but also helps businesses optimize processes and reduce long-term operating costs.
