1.Problem
In the water and sanitation sector of El Salvador, Company H has long faced challenges in wastewater measurement. Wastewater contains a large amount of impurities, which interfere with traditional flow measurement equipment, resulting in large measurement errors. This leads to deviations in wastewater discharge statistics, environmental monitoring, and cost accounting, affecting work efficiency and making it difficult to meet the data accuracy requirements of environmental protection departments. Meanwhile, wastewater treatment scenarios are diverse, and traditional equipment has poor adaptability, low pipe diameter matching, a narrow flow measurement range, and insufficient stability and durability under harsh working conditions such as temperatures from -20°C to 120°C and pressures of 4.0 MPa, with frequent breakdowns and high maintenance and replacement costs.
2.Requirements
Company H urgently needs flow metering equipment with a measurement accuracy of 0.5% to ensure accurate wastewater metering. The equipment must be compatible with pipeline specifications such as DN50, have a flow range covering 3.5 - 35m³/h, be able to operate stably under working conditions of -20°C - 120°C and 4.0MPa, feature diverse signal outputs such as pulse, 4 - 20mA, and RS485 for easy integration with existing systems. The lining and electrodes need to be corrosion-resistant and wear-resistant, with the main body made of carbon steel to ensure strength, and a split structure for easy installation and maintenance.
3.Product Configuration
Measurement accuracy: 0.5%;
Flow range: 3.5 - 35 m³/h;
Power supply: 220VAC;
Signal Output: Pulse, 4 - 20mA Analog, RS485 Digital Communication;
Lining material: PTFE (Polytetrafluoroethylene);
Electrode material: SS316L stainless steel;
Connection method: flange connection;
Pressure Rating: 4.0 MPa;
Temperature Range: -20°C - 120°C;
Main material: carbon steel;
Structure Type: Split Type.
4.Solution
Jujea has established an efficient communication mechanism with Company H. In response to the compatibility issues of the existing wastewater system in El Salvador, it has made customized adjustments to the Communication Protocol of electromagnetic flow meters and provided detailed installation and commissioning guidance. During production, strict quality inspections and aging tests are conducted on key components to ensure the stable performance of the equipment under conditions of containing impurities, extreme temperature, and pressure. The PTFE lining and SS316L electrodes effectively address the corrosion and wear caused by wastewater impurities.
5.Results
Jujea is a well-known brand manufacturer of flow measurement and control in China, specializing in high-quality instrumentation
products. Since the commissioning of the electromagnetic flowmeter of this brand, its 0.5% accuracy has solved the problem of insufficient accuracy in traditional equipment, making wastewater statistics and environmental protection monitoring more accurate, and improving the work efficiency and environmental protection image of Company H. The equipment is compatible with DN50 pipelines, has a wide flow range coverage, strong temperature and pressure adaptability, fewer failures, and reduces operation and maintenance costs. The diversified signal output enables seamless integration with existing systems, allowing real-time monitoring of wastewater conditions, assisting Company H in scientific management and scheduling, improving the overall level of wastewater management, and laying the foundation for future cooperation between the two parties.
