4. セットアップとインストール

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. シーラントを塗布する: 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. 漏れがないか確認する: 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. 操作

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.

• 電源オン: The display is powered by two field-replaceable lithium batteries. It will automatically activate when flow is detected or when a button is pressed.
• 表示モード： 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.
• 較正： 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. メンテナンス

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

• バッテリー交換: 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.
• クリーニング： Periodically inspect the meter for external debris. Clean the display and housing with a damp 布で拭いてください。研磨剤や溶剤は使用しないでください。
• 内部部品： The internal parts are designed for simple replacement, facilitating ease of maintenance. If internal components require service, contact FLOMEC support or a qualified technician.
• 濡れた材料： 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。 トラブルシューティング

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

• ディスプレイなし/バッテリー残量が少ない: Check the battery indicator. If low, replace the batteries. Ensure proper battery orientation.
• 不正確な読み取り: Verify the flow direction is correct. Check for air bubbles or debris in the fluid stream. Consider performing a field calibration if necessary.
• フロー読み取りなし: 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).
• リーク: Re-check all threaded connections for proper sealant and tightness.

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