Large-Diameter Electromagnetic Flowmeters – Selection & Troubleshooting

Large-Diameter Flowmeter Guide: Easy Selection & Maintenance

Large electromagnetic flowmeters are used to measure water flow in large pipes (DN200-DN2000). These devices play a key role in:

  • Supplying clean water to cities
  • Treating wastewater at plants
  • Transporting liquids through factories

Simplified Installation

Handling Heavy Equipment

These units weigh 10-50kg. Always use proper lifting equipment and have at least two people to help with installation.

Selecting Durable Materials

For durability, choose 316L steel models. Ceramic liners provide extra protection against wear.

Reducing Vibration

Install supports every 2 meters to reduce vibration. Shock-absorbing mounts help protect the equipment.

Note: High-quality units weigh more due to thicker, stronger materials.

Easy Maintenance Steps

Checking Electrode Health

Test for buildup that could affect accuracy. Healthy electrodes should read under 20kΩ.

Quick 3-Step Test:

  1. Turn off the power
  2. Measure resistance in the liquid
  3. Compare both electrodes

Testing Voltage Levels

Check for contamination by measuring voltage levels. Properly working units maintain voltage differences below 300mV.

Simple Measurement:

  1. Set to DC 2V setting
  2. Test each electrode
  3. Confirm voltage differences are minimal
