Kind Tips

 

To ensure optimal accuracy and longevity of yourelectromagnetic flow meter, please adhere to the following guidelines during installation, operation, and maintenance.

 

1. Installation & Commissioning

·Ensure Full Pipe Flow: For precise measurement, always install the meter in a location that guarantees the pipeline is completely full. Avoid mounting at the highest point of a pipeline where air can accumulate.

·Correct Electrode Orientation: Mount the sensor with the electrode axis horizontal to prevent air bubbles from becoming trapped on the electrodes, which can cause measurement errors.

 

2. Calibrate for Accuracy: Perform a zero-point calibration after initial installation or whenever the measured medium is changed to eliminate any residual offset from the empty pipe.

 

3. Routine Maintenance

·Check the electrode condition regularly and clean any scaling or contamination.

·When using in low-temperature environments, be careful to prevent the medium from freezing and damaging the sensor.

 

4. Extended Shutdown & Troubleshooting

·If the system is to be shut down for an extended period, drain the liquid from the flow meter and the adjacent piping. Store the unit in a dry environment to prevent internal corrosion.

·If you experience unstable or inaccurate flow readings, please check the power, grounding, and signal connections. If you have persistent problems with your electromagnetic flow meter, please contact our technical team and we will resolve the issue for you.

 

FAQ

Q: What are the key advantages of an Electromagnetic Flow Meter over other types of flow meters?

A: Electromagnetic flow meters excel at measuring conductive liquids, require no moving parts, eliminate pressure loss, and minimize maintenance, and are virtually unaffected by changes in fluid density, viscosity, temperature, or pressure.

Q: How do I handle zero-point calibration, and when is it necessary?

A: Zero calibration should be performed after installation, after any maintenance, or when switching between vastly different media. The process is done with the pipe filled with a stationary liquid. Our devices feature a simple, guided zero-calibration function to ensure accuracy is easily maintained.

Q: Can electromagnetic flow meters measure fluids containing solid particles or slurries?

A: Absolutely. Since the measurement is based on conductivity and there are no obstructions in the flow path, our flow meters are ideal for measuring abrasive slurries, sewage, pulp and other fluids containing solid particles.

Q: Can you customize the sensor for specific applications?

A: Definitely. We offer extensive OEM and customization services. This includes custom cable lengths, connector types, housing materials, specific thread sizes, output signals, and even branding with your logo to meet your specific needs.

Q: What is your typical lead time for standard and custom products?

A: For standard products, we strive to ship within 2-4 weeks. Lead times for custom orders vary based on the complexity but typically range from 12-weeks. We will always provide a firm timeline upon receipt of your inquiry.
