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:
- Turn off the power
- Measure resistance in the liquid
- Compare both electrodes
Testing Voltage Levels
Check for contamination by measuring voltage levels. Properly working units maintain voltage differences below 300mV.
Simple Measurement:
- Set to DC 2V setting
- Test each electrode
- Confirm voltage differences are minimal
