Insertion Electromagnetic Flowmeter CLD-8028

Henan Zhongce Sensor Manufacturing Co., Ltd. has launched the CLD‑8028 insertion-type electromagnetic flowmeter, specifically designed for flow measurement in large‑diameter pipelines. It is widely applicable in water supply networks, raw water transmission and distribution, circulating water systems, district metering, and hydraulic engineering projects. While ensuring measurement accuracy, this product significantly reduces the overall cost of large‑diameter flowmeters and supports online installation without interrupting water service, offering a convenient solution for pipeline upgrades and the addition of metering nodes.

Wide measurable caliber range

The CLD-8028 is suitable for pipe diameters ranging from DN100 to DN3000, covering the vast majority of applications—from small and medium‑size branch lines to large main pipelines. The sensor features an insertion‑type design: the probe is inserted into the pipeline via a ball valve or a dedicated mounting base. Installation is typically positioned near the point of average flow velocity in the pipe cross‑section, with total flow rate calculated using the velocity‑area integration method.

Nylon probe

The probe body is made of nylon (polyamide) and possesses the following characteristics:

Excellent insulation performance effectively shields against external electromagnetic interference, ensuring the faithful transmission of weak flow signals.

Excellent corrosion resistance, suitable for neutral water, raw water, tap water, and mildly acidic or alkaline environments.

The material has a low density and a light overall weight, facilitating on-site installation and reducing the load on the mounting brackets.

The surface is resistant to scale and biofilm formation, and with regular maintenance, it can maintain signal stability over long-term operation.

Non-stop water supply, online pressurized installation

The CLD-8028 enables installation to be carried out while the pipeline remains in normal operation, eliminating the need to shut off water, relieve pressure, or drain the pipeline. During installation, a mounting base is first welded onto the outer wall of the pipe and fitted with a ball valve; then, using a dedicated hole‑making tool, an opening is created under pressure. Finally, the probe is inserted into the pipeline through the ball valve and securely sealed and locked in place. This installation method minimizes disruption to production operations and residential water supply, making it well suited for scenarios requiring on‑line construction, such as metering upgrades of existing networks and densification of district‑level metering nodes.

The Economical Choice for Metering Large-Diameter Pipelines

Compared with in-line electromagnetic flowmeters of the same nominal diameter, insertion-type designs reduce material consumption, manufacturing costs, and transportation and installation expenses to varying degrees; the larger the pipe diameter, the more pronounced the economic advantages. For large-diameter water‑transmission pipelines with a nominal size of DN800 or greater, the CLD‑8028 represents an optimal solution for balancing measurement requirements with project budgets.

Converter Function Configuration

The accompanying converter features a 4–20 mA analog output, a pulse output, and an RS‑485 communication interface, and supports the Modbus protocol.

Installation and Usage Highlights

The installation location should be selected in a straight pipe section with sufficient length, avoiding flow‑disturbing components such as bends, valves, and tees. The probe insertion depth shall be determined based on the pipe’s inner diameter and the velocity‑field distribution, ensuring that the electrodes are positioned at a location representative of the average flow velocity. For large‑diameter pipelines, it is advisable to perform an on‑site flow‑field calibration prior to installation or to apply corrections using a theoretical velocity‑distribution model.

Henan Zhongce Sensor Manufacturing Co., Ltd. offers comprehensive factory calibration and testing. Each CLD‑8028 insertion-type electromagnetic flowmeter undergoes flow‑rate calibration and insulation‑performance testing before leaving the factory. We can provide probe insertion‑depth calculations, installation‑scheme recommendations, and on‑site commissioning support tailored to your pipeline parameters, process conditions, and installation environment.
