Deskripsi
Product Advantages:
The core value of the insert-type electromagnetic flowmeter lies in its exceptional cost-effectiveness, ease of installation and maintenance, and economic efficiency for large-diameter measurements.
- Large-diameter measurement with optimized costs: For pipelines larger than DN300, its procurement cost is only one-third to one-half that of full-bore electromagnetic flowmeters. The larger the pipe diameter, the more pronounced the economic advantage, delivering an extremely high return on investment.
- Installation and Maintenance Without Production Halt: Utilizing specialized ball valves and drilling tools, installation and maintenance can be completed under pressure without production interruption. This significantly reduces installation costs and production downtime losses, making it particularly suitable for retrofit projects.
- Minimal Pressure Loss, Energy-Efficient and Eco-Friendly: Only a small probe is inserted into the pipeline, resulting in negligible pressure loss. Long-term operation saves substantial pumping energy consumption, delivering significant energy-saving benefits.
- Easy Maintenance, Low Cost: Sensor probes can be inserted or removed online via ball valves without draining pipelines or halting production. For future replacements or repairs, only the low-cost probe needs replacement, not the entire meter body.
- High Reliability, Strong Interference Resistance: Leveraging electromagnetic principles, measurements remain unaffected by changes in fluid temperature, pressure, density, or viscosity. Output signals are stable with robust interference resistance.
- Wide Applicability: Measures various conductive liquids including water, slurries, acids, and alkalis (conductivity >5μS/cm). Offers multiple electrode and lining materials (e.g., 316L, Hastelloy, PTFE) for corrosive media.
Core Application Areas:
- Water and Wastewater Treatment: Flow monitoring for main inflow/outflow pipelines (DN300+) at raw water/wastewater treatment plants, and stormwater discharge monitoring.
- Municipal Water Management and Irrigation: Flow measurement for large diversion channels, water supply networks, and agricultural irrigation canals (requires metering wells).
- Industrial Circulating Water Systems: Water volume assessment and energy management for factory cooling circuits, fire protection water, and main inlet/return pipelines.Power and
- Metallurgy Industries: Monitoring of circulating cooling water, ash-washing water, and slurry flow in large pipelines.
- Chemical and Pulp & Paper Industries: Process monitoring and total volume measurement of conductive liquids in large-diameter pipelines.
