3. Product Overview

The FLOMEC G2B15N09GMB is a G2 Series brass turbine flowmeter designed for accurate measurement of fluid flow. It features a 1.5-inch FNPT inlet/outlet and provides an accuracy of +/-0.75 percent of reading for flow rates ranging from 10 to 100 GPM (38 to 380 LPM). The brass housing ensures compatibility with a wide range of water-based applications, including glucose, juice, and lacquer thinner.

Key features include:

• High Accuracy: Provides precise flow measurement with +/-0.75% accuracy.
• Versatile Application: Compatible with various water applications due to its brass housing and wetted materials.
• Digital Display: Equipped with a 6-digit LCD display showing resettable batch total, non-resettable cumulative total, and rate of flow.
• Modular Design: Allows for integration with output modules, sensors, and remote transmitters.
• Easy Maintenance: Simplified internal parts and field-replaceable batteries contribute to ease of service.

4. Setup and Installation

The FLOMEC G2B15N09GMB flowmeter features a compact design for straightforward installation. Ensure the flowmeter is installed in the correct orientation, aligning the flow direction arrow on the meter body with the direction of fluid flow in the pipe. The meter utilizes 1.5-inch FNPT (Female National Pipe Taper) connections for integration into your piping system.

1. Prepare the Piping: Ensure the piping system is clean and free of debris before installation.
2. Apply Sealant: Use an appropriate thread sealant on the 1.5-inch FNPT connections to prevent leaks.
3. Install Meter: Thread the flowmeter into the pipeline, ensuring the flow arrow on the meter body points in the direction of fluid flow. Tighten connections securely but do not overtighten.
4. Check for Leaks: After installation, slowly introduce fluid into the system and check all connections for leaks.
5. Modular Integration: If using optional output modules, sensors, or remote transmitters, refer to their respective manuals for connection instructions.

5. Operation

The FLOMEC G2B15N09GMB flowmeter is equipped with a 6-digit LCD display that provides real-time flow data. The display shows a resettable batch total, a non-resettable cumulative total, and the current rate of flow. The meter is factory calibrated in gallons but allows for field calibration if required.

• Power On: The display is powered by two field-replaceable lithium batteries. It will automatically activate when flow is detected or when a button is pressed.
• Display Modes: Use the 'DISPLAY' button to cycle through the different display modes: Rate of Flow, Resettable Batch Total, and Non-Resettable Cumulative Total.
• Resetting Batch Total: To reset the batch total, navigate to the batch total display mode and press and hold the 'CALIBRATE' button until the total resets.
• Calibration: For field calibration, refer to the detailed calibration procedure in the full product manual. The 'CALIBRATE' button is used in conjunction with specific flow rates to adjust accuracy.

6. Maintenance

Regular maintenance ensures the continued accuracy and reliability of your FLOMEC G2B15N09GMB flowmeter.

• Battery Replacement: The meter is powered by two lithium batteries with an approximate 5-year life. When the battery indicator appears, replace the batteries promptly. Non-volatile totals protect meter data during battery replacement.
• Cleaning: Periodically inspect the meter for external debris. Clean the display and housing with a damp cloth. Do not use abrasive cleaners or solvents.
• Internal Parts: The internal parts are designed for simple replacement, facilitating ease of maintenance. If internal components require service, contact FLOMEC support or a qualified technician.
• Wetted Materials: The wetted materials include 316 Stainless Steel, brass, Ceramic, PVDF, and Tungsten Carbide, chosen for compatibility with various fluids. Ensure the fluid being measured is compatible with these materials to prevent corrosion or damage.

7. Troubleshooting

If you encounter issues with your FLOMEC G2B15N09GMB flowmeter, consider the following basic troubleshooting steps:

• No Display/Low Battery: Check the battery indicator. If low, replace the batteries. Ensure proper battery orientation.
• Inaccurate Readings: Verify the flow direction is correct. Check for air bubbles or debris in the fluid stream. Consider performing a field calibration if necessary.
• No Flow Reading: Ensure there is actual fluid flow through the meter. Check for blockages in the pipeline. Verify the turbine is rotating freely (if accessible and safe to inspect).
• Leaks: Re-check all threaded connections for proper sealant and tightness.

For persistent issues or complex problems, contact FLOMEC technical support.
