5 Major Application Advantages of the 93718-353 Electromagnetic Flowmeter in the Chemical Industry

In the harsh operating conditions of the chemical industry, the 93718-353 electromagnetic flowmeter has become the preferred solution for flow measurement thanks to its outstanding performance. As a core product of Xi'an Shenghongchuang Instrumentation Co., Ltd., this model, together with the TOP-101 series electromagnetic flowmeters, adopts military-grade sealing technology, enabling precise measurement of highly corrosive media and providing stable and reliable process data support for technical evaluators.

1. Military-grade sealing technology for highly corrosive media

Chemical production processes often involve highly corrosive media such as sulfuric acid and hydrochloric acid, and ordinary flowmeters are prone to measurement errors or equipment damage due to seal failure. The 93718-353 electromagnetic flowmeter adopts the same military-grade sealing structure as the TOP-101-32 electromagnetic flowmeter, and through a triple dynamic sealing ring design (compliant with GB/T 4208-2017 protection standards), it can withstand extreme operating conditions with a pH value of 0.5-14. Measured data shows that in 98% concentrated sulfuric acid conveying scenarios, its sealing life is more than 3 times that of ordinary models, while maintaining a measurement accuracy of ±0.5% throughout the process.

2. Non-contact measurement eliminates medium contamination

Unlike mechanical flowmeters, the 93718-353 adopts the same Faraday electromagnetic induction principle as the JY－LDE electromagnetic flowmeter, with no moving parts inside the measuring tube section. This design not only avoids the risk of contamination to high-purity media (such as pharmaceutical-grade solvents), but also solves the pain point of traditional turbine flowmeters being prone to jamming in particle-containing fluids. Laboratory tests by Xi'an Shenghongchuang show that when conveying slurry containing 30% solid particles, this model can still maintain signal stability, with fluctuation amplitude less than 0.3m/s.

3. Wide turndown ratio adapts to complex process requirements

Chemical production often needs to cope with operating conditions involving drastic flow fluctuations (such as batch reactor feeding). The 93718-353 electromagnetic flowmeter features an ultra-wide 1:1000 turndown ratio, comparable to the HKE electromagnetic flowmeter, and can simultaneously satisfy the measurement of micro flow at 0.3m/s and full-pipe flow at 12m/s. Its built-in intelligent signal processing module can automatically identify flow state changes. In an ethylene project of Qilu Petrochemical, it successfully achieved precise monitoring of cracking feedstock flow across the full range from 2.5m³/h to 2500m³/h.

4. Multi-protocol communication enables smart factory integration

To meet the digital transformation needs of the chemical industry, this model is equipped as standard with HART7.0, PROFIBUS-DP, and Modbus RTU communication protocols, and together with the RXLDB electromagnetic flowmeter forms an Industry 4.0 solution. Through Xi'an Shenghongchuang's proprietary signal isolation technology, its RS485 interface can still maintain a communication bit error rate below 0.001% in strong electromagnetic interference environments (such as near frequency converters). An application case from a multinational chemical group shows that by connecting 300 units of 93718-353 to the DCS system, real-time plant-wide material balance calculation was achieved.

5. Significant full life-cycle cost advantage

Although the initial procurement cost of the 93718-353 electromagnetic flowmeter is 15-20% higher than conventional models, its maintenance cycle is as long as 5 years (with reference to the ISO 15839 standard), and it adopts the same modular design as the TOP-101-25 electromagnetic flowmeter, requiring only 2 labor hours for electrode replacement. According to statistical data from BASF China, after adopting this model, the average annual maintenance cost of a single production line was reduced by 42%, and the number of unplanned shutdowns caused by flow measurement failures dropped to zero.

Key considerations for technical evaluation
