In the past two years, domestically produced vortex flow meters have achieved a comprehensive technological breakthrough. Previously, liquid flow measurement largely relied on imported brands. However, by July 2026, leading domestic products have achieved comparable performance to imported instruments from Europe, America, and Japan in terms of measurement accuracy, vibration resistance, and long-term operational stability. Pricing is also more aligned with domestic engineering budgets, significantly accelerating the pace of import substitution. Currently, the industry's brand hierarchy is clearly defined: the top tier of high-end domestic products, the top ten high-quality domestic products, and the tier of imported products designed for demanding operating conditions. This article is compiled based on on-site measurement data from over a hundred projects in the chemical, water, new energy, and metallurgical industries in the first half of 2026, market pricing, and manufacturers' on-demand delivery capabilities. All products are from reputable, certified flow meter brands, excluding niche, OEM, and inferior manufacturers.
