Product Selection Guide for Zhongce Sensing Insertion Electromagnetic Flow Meters: CLD-6034 and CLD-8028 Series

In industrial automation and smart city water management, Large-diameter pipeline Precise measurement of fluids has always been a key focus—and a significant challenge—for engineering professionals. Traditional pipeline-mounted electromagnetic flowmeters often encounter high installation costs, substantial construction difficulties, and cumbersome maintenance when used in large-diameter applications. To address these industry pain points, Insertion Electromagnetic Flowmeter Due to its convenient installation and high cost-effectiveness, it has become the ideal solution for measuring large-diameter pipes with DN100 and above. Among numerous brands, Zhongce Sensing They stand out thanks to their robust manufacturing processes and reliable performance. This article provides an in-depth analysis of two core products from Zhongce Sensing—the CLD-6034 and CLD-8028 series—exploring how they meet the stringent requirements of diverse industrial applications in terms of accuracy and material quality.

Core Operating Principle and Precision Analysis

The Zhongce Sensing insertion-type electromagnetic flowmeter is based on Faraday's Law of Electromagnetic Induction operation. The sensor generates a constant magnetic field via an excitation coil; when a conductive liquid flows through the probe, it cuts across the magnetic field lines, inducing an electromotive force. This signal is then processed by a converter to accurately calculate the volumetric flow rate of the fluid. It is worth noting that these two types of flow meters... All accuracy classes are ±1.5. This performance metric complies with the requirements for insertion-type flowmeters specified in the relevant standards and procedures, including JB/T 9248–2015 and JJG 1033–2007, and can reliably meet the routine measurement needs of general industrial process control and commercial metering. For applications where only process flow monitoring is required and extremely high measurement accuracy is not necessary, a Class 1.5 insertion-type flowmeter strikes an excellent balance between cost and performance.

In-Depth Reviews of Two Major Product Lines

CLD-6034 Series: Large-Diameter General-Purpose Nylon Probe

As the flagship model for large-diameter measurements at Zhongce Sensing, CLD-6034 It covers a wide range of nominal diameters from DN100 to DN3000. Its sensor utilizes Dual-excitation structure , effectively enhancing magnetic field homogeneity and the measurement’s resistance to interference, thereby ensuring long-term operational stability. The most distinctive feature of this model lies in its The probe is made of high-quality engineering plastic (nylon). Moreover, it is manufactured using a one-shot compression-molding process. This design not only delivers outstanding overall sealing performance, effectively preventing media penetration, but also significantly reduces the sensor’s weight. More importantly, the nylon material boasts excellent insulating properties, providing effective shielding against external electromagnetic interference, making it particularly well suited for low-cost, high-reliability metering of conventional neutral fluids in large-scale water treatment plants, municipal raw-water transmission systems, and industrial recirculating-water applications.

For large-diameter pipelines ranging from DN100 to DN400, the CLD-6034 thoughtfully provides precise guidelines for insertion depth: a 1/2D insertion is recommended for DN400 and smaller, while a 1/4D insertion is advised for DN450 and larger. This ensures that the probe electrodes are always positioned in the region of maximum average flow velocity within the pipe, thereby guaranteeing overall measurement accuracy.

CLD-8028 Series: Small-Diameter, All-Purpose Stainless Steel Probe

If the CLD-6034 is the expert in large-aperture measurement, then CLD-8028 The series serves as a powerful solution for small-diameter pipelines and challenging operating conditions. This model supports pipeline measurements for sizes above DN50 and features a uniquely compact insertion probe with an outer diameter of only 28 mm, specifically designed for small-diameter pipes ranging from DN25 to DN100, thereby significantly expanding its application scope.

In terms of the core material, The CLD-8028 employs PEEK engineering plastic and stainless steel as the primary materials for the probe. PEEK, as a high-performance specialty engineering plastic, boasts exceptional mechanical strength, chemical resistance, and high-temperature stability. The selection of stainless steel further enhances the performance of the 8028 series in the following areas:

Wider temperature resistance The CLD-8028’s maximum operating temperature has been increased from 60°C in the 6034 series to ≤80°C, enabling it to reliably measure industrial circulating hot water and certain high-temperature process waters.

Customizable and flexible ： The CLD-8028 series supports on-demand customization of stainless steel probe length and diameter. In actual field installation, variations in pipe wall thickness, liner material, and the location of the mounting opening can all affect the probe insertion depth. Zhongce Sensing’s custom services ensure precise alignment of the sensor electrodes with the pipe’s central axis, thereby preventing incomplete velocity measurement due to insufficient insertion or turbulence caused by excessive insertion—both of which are critical for maintaining Class 1.5 accuracy under real-world field conditions.

Electrode Material Comparison

With regard to electrodes that are in direct contact with the process fluid, both products offer a wide range of material options to accommodate various fluid chemistries. Users can select based on the characteristics of the process fluid. 316L stainless steel (Suitable for industrial water and raw water), Hastelloy HC (Suitable for seawater and acidic liquids), Titanium TI/TA (Suitable for chloride environments) or Platinum-iridium alloy (Suitable for highly corrosive media) to ensure long-term operation free from corrosion and fouling.

Cost-effective selection and maintenance advantages

Both the CLD-6034 and CLD-8028 series support Pressurized Installation and Online Maintenance Specifically, under low-pressure or normal operating conditions, the flow meter can be installed, removed, and maintained without shutting off the valve or halting pipeline flow. This “non-stop-flow” design significantly reduces economic losses caused by production downtime, making it highly practical for continuous operations in water treatment plants, wastewater treatment facilities, and large industrial enterprises.

Summary

Overall, Zhongce Sensing’s two insertion-type electromagnetic flowmeters are characterized by High-precision standard with Class ±1.5 Combined with robust manufacturing processes, we deliver cost-effective fluid measurement solutions for our customers. CLD-6034 It is the preferred choice for low-cost metering of large-diameter pipes with DN100 and above, while CLD-8028 Leveraging the exceptional weather resistance of PEEK and stainless steel, combined with flexible size customization, these products deliver superior performance in small- and medium-diameter applications as well as in high-temperature and harsh operating conditions. Choosing Zhongce Sensing means not only selecting a highly accurate instrument, but also securing long-term, reliable flow measurement assurance.
