In the demanding fluid measurement environment of the chemical industry, the AKT-LD electromagnetic flowmeter has become a benchmark solution thanks to its high accuracy and corrosion resistance. This article analyzes through practical application cases how the AKT-LD electromagnetic flowmeter overcomes the challenges of measuring strong acid and strong alkali media, providing reliable equipment selection reference for business evaluation personnel.

Core Challenges of Flow Measurement in the Chemical Industry

Chemical production processes often involve strong acids, strong alkalis, high-viscosity media, or media containing particulate matter, and traditional mechanical flowmeters are prone to wear, scaling, and corrosion. According to 2022 data from the China Petroleum and Chemical Industry Federation, process accidents caused by flow measurement failure accounted for 17% of unplanned shutdowns in the industry. The AKT-LD electromagnetic flowmeter developed by Xi'an Shenghongchuang Instrumentation Co., Ltd. adopts a special fluororubber lining material combined with an insertion-type design, can withstand extreme working conditions with a pH value of 0-14, and delivers measurement accuracy up to ±0.5%, making it the preferred solution for chlor-alkali, pesticides, dyes, and other segmented fields.

Analysis of the Technical Features of the AKT-LD Electromagnetic Flowmeter

This product addresses industry pain points through the following innovative designs: first, the patented electrode structure uses titanium alloy coated platinum material, combined with the homologous technology of the HD-LDE series, ensuring stable signal output even in 98% concentrated sulfuric acid; second, the modular design supports the rapid maintenance function of the DEC-LD electromagnetic flowmeter, reducing average maintenance time by 60%; third, the double-shielded cable compliant with the ISO9104 standard can effectively suppress frequency converter interference—in one application case at a large chemical fiber enterprise, this reduced the data fluctuation rate from 3.2% to 0.8%. The main product parameters are shown in the table below:

Typical Application Scenarios and Comparison of Economic Benefits

In a 32% caustic soda transportation project of a multinational chemical group, the ZY-LDE electromagnetic flowmeter and the AKT-LD electromagnetic flowmeter underwent an 18-month parallel test. The results showed that, due to its insertion-type fluororubber lining structure, the latter extended the maintenance cycle from 3 months to 24 months when dealing with alkali crystallization issues, saving 470,000 yuan in annual maintenance costs for a single production line. More importantly, its ±0.3% batch proportioning accuracy increased the product qualification rate by 2.1 percentage points, directly creating annual benefits of over 3 million yuan.

Five Key Dimensions for Selection Decision-Making

Business evaluation personnel should focus on: 1) medium conductivity requirements（recommended >5μS/cm）; 2) straight pipe section conditions（5D upstream and 3D downstream are optimal）; 3) explosion-proof certification（such as ATEX or IECEx if required）; 4) output signal compatibility（4-20mA/HART protocol）; 5) life cycle cost. It is worth noting that Xi'an Shenghongchuang's DEC-LD electromagnetic flowmeter has passed SIL2 functional safety certification, giving it unique advantages in scenarios involving interlock protection.
