In the field of industrial flow measurement, the TC-DCZHQ electromagnetic flowmeter is reshaping traditional installation methods with its innovative insertion design and fluororubber lining technology. This article provides an in-depth analysis of how this product, through its no pipe-cutting installation feature, saved 90% of construction costs for a large water treatment project while maintaining measurement accuracy.

I. Industry Pain Points and Solutions

Traditional pipeline flowmeter installation requires pipe cutting and flange welding, which not only extends the construction period to 3-5 days, but also incurs high downtime costs. The TC-DCZHQ series developed by Xi'an Shenghongchuang adopts a military-grade insertion structure, requiring only a Φ25mm hole to be opened on the pipeline to complete installation. In an actual renovation project at a wastewater treatment plant, the original installation cost of 120,000 yuan was reduced to 12,000 yuan. Its patented fluororubber lining technology (compliant with GB/T18660-2018 standard) can withstand strong acid and alkali media, while measurement accuracy remains at the industry-leading level of ±0.5%R.

II. Analysis of Core Technical Parameters

This model of electromagnetic flowmeter adopts unique dual-frequency excitation technology, effectively solving the measurement challenge of low-conductivity liquids (≥5μS/cm). Key parameters include: full bore coverage from DN50-DN2000, a flow velocity range of 0.1-10m/s, and an operating temperature of -30℃~+180℃. Compared with similar HYLD electromagnetic flowmeters, its adjustable insertion depth design (±10mm) can adapt to different pipe diameter requirements, and the matching TC-ZNDC signal converter supports 4-20mA/HART dual output modes.

III. Application Verification in the Chemical Industry

In the renovation of a concentrated hydrochloric acid transport pipeline at a chlor-alkali chemical plant in Shaanxi, the TC-DCZHQ electromagnetic flowmeter demonstrated three major advantages: 1) the electrode assembly with fluororubber lining perfectly resists corrosion from hydrochloric acid at a concentration of 40%; 2) through the GPRS remote calibration function, non-stop production maintenance is achieved; 3) the matching TC-GYDC explosion-proof model has passed NEPSI certification and meets ExdⅡCT6 explosion-proof requirements. Feedback from the chief project engineer indicated that, compared with the original TC-FFDC split-type solution, the new equipment reduced annual maintenance costs by 67%.

IV. Selection Guide and Common Misunderstandings

Technical evaluators should note: 1) although the insertion design saves costs, it requires an upstream straight pipe section of ≥10D (the TC-CDC model can be shortened to 5D); 2) when measuring pure water with conductivity <20μS/cm, it is recommended to select the TC-WSDC high-frequency version; 3) media containing solid particles require the TC-QSDC wear-resistant electrode. Xi'an Shenghongchuang provides free pipeline compatibility analysis services and can customize installation components according to the ASME B16.5 standard.
