Specifications

Setup and Installation

Proper installation is crucial for the accurate and reliable operation of the GOWE LUGB vortex street flow meter. It is recommended that installation be performed by qualified personnel.

1. Site Selection: Choose a location with stable temperature and minimal vibration. Ensure sufficient straight pipe lengths upstream and downstream as per industry standards (typically 10-20D upstream and 5D downstream, where D is the nominal diameter).
2. Mounting Orientation: Install the flow meter in a horizontal or vertical pipeline, ensuring the flow direction arrow on the meter body aligns with the actual fluid flow.
3. Flange Connection: Use appropriate gaskets and tighten bolts evenly to prevent leaks. Ensure the meter is properly aligned with the pipeline.
4. Electrical Connections: Connect the power supply (12-36 VDC) and output signals (4-20mA, pulse) according to the wiring diagram provided with the product. Ensure proper grounding to prevent electrical interference.
5. Pressure and Temperature Compensation Lines: If applicable, connect the pressure and temperature compensation lines to the appropriate points on the pipeline and the meter's compensation unit.
6. Initial Power-Up: After installation, apply power and observe the display. Verify basic functionality before introducing process fluid.

Note: Refer to the detailed wiring diagrams and specific installation guidelines included in the product packaging for precise instructions.

Operating Instructions

Once installed and powered, the GOWE LUGB vortex street flow meter is designed for continuous operation. The integrated display provides real-time data.

1. Display Navigation: Use the buttons on the display unit (if present) to cycle through different readings such as instantaneous flow, totalized flow, and percentage flow.
2. Parameter Configuration: Access the configuration menu (refer to the product's specific manual for access method) to set parameters such as fluid type, pipe diameter, and output scaling.
3. Monitoring Output: Monitor the 4-20mA current output or pulse output at your control system to integrate the flow data into your process control.
4. Data Logging: If connected to a data logging system, ensure data is being recorded correctly.

Always ensure the process fluid is within the specified temperature and pressure limits of the flow meter.

Maintenance

Regular maintenance ensures the longevity and accuracy of your flow meter.

• Routine Inspection: Periodically inspect the meter for any signs of leakage, corrosion, or physical damage. Check electrical connections for tightness.
• Cleaning: Keep the exterior of the meter clean. Avoid using abrasive cleaners.
• Sensor Check: While the vortex sensor is generally robust, ensure there are no obstructions or build-up within the flow path that could affect accuracy. This may require temporary removal from the pipeline.
• Recalibration: Depending on application and regulatory requirements, periodic recalibration may be necessary to maintain accuracy. Consult a qualified technician for recalibration services.
• Gasket Replacement: If the meter is removed from the pipeline for any reason, always replace the gaskets before reinstallation.

Before performing any maintenance, ensure the process fluid flow is stopped, the pipeline is depressurized, and the meter's power supply is disconnected.
