Henan Zhongce Sensing ZT-EMF Series Pipeline Electromagnetic Flowmeters: Class 0.2 accuracy, with support for calibration and verification.

In the field of industrial fluid measurement, electromagnetic flowmeters have become core metering devices in industries such as water treatment, chemical engineering, and metallurgy, thanks to their high measurement accuracy, zero pressure loss, and broad compatibility with various media. Henan Zhongce Sensing Technology Co., Ltd. has launched… ZT-EMF Series Pipeline Electromagnetic Flowmeter It has been systematically designed in terms of accuracy class, environmental adaptability, and compliance with testing requirements, providing users with a stable and reliable flow‑measurement solution.

1. Measurement accuracy can reach Class 0.2, meeting stringent metrological requirements.

The ZT-EMF series electromagnetic flowmeters are based on Faraday’s law of electromagnetic induction. The sensor generates a voltage signal that is linearly proportional to the average fluid velocity, and their measurement accuracy remains unaffected by variations in fluid density, viscosity, temperature, pressure, or electrical conductivity. This series offers multiple accuracy classes for users to choose from, among which… 0.2-class accuracy model It is suitable for applications with stringent requirements for trade settlement or process control, offering a flow measurement range of up to 150:1 while maintaining excellent linearity and repeatability across a wide span.

II. Internal full‑potting encapsulation process, enhancing adaptability to harsh environments.

The ZT-EMF series sensors and transducers internally employ Full potting process The circuit board and critical electronic components are fully encapsulated in epoxy resin, forming a dense protective layer. This process effectively safeguards the internal circuitry against environmental factors such as moisture, condensation, and dust, enabling the entire unit to achieve an IP68 protection rating and operate reliably for extended periods underwater or in high-humidity environments. For applications requiring outdoor installation, pit‑mounted deployment, or operation in damp industrial facilities, the all‑encapsulated design significantly reduces the risk of signal drift or failures caused by degraded insulation.

III. Support for sample submission to testing, ensuring compliance with metrology regulations and regulatory management.

The ZT-EMF series products can be customized to meet user requirements. Submit to a legally authorized metrological verification institution for verification. and issue a certificate of compliance. The verification is conducted in accordance with JJG 1033, the Verification Procedure for Electromagnetic Flow Meters, and is performed by metrological verification institutions authorized by quality and technical supervision authorities at or above the prefectural level. For industries such as municipal water supply, heating, and chemical processing—where mandatory or periodic verification is required by law—the ZT‑EMF series can support both initial verification and subsequent periodic checks, helping users meet metrological compliance requirements and mitigating operational risks arising from measurement disputes.

4. Dedicated high-precision meter head, with comprehensive functions and convenient operation.

ZT-EMF series matching Dedicated high-precision converter meter head It employs a low-power, high-performance microcontroller and surface-mount technology, offering features such as zero-point stability, rapid response, and strong anti-interference capability. The meter’s display unit is equipped with a high‑resolution backlit LCD, supports Chinese‑language menu operation, and can simultaneously show multiple parameters including instantaneous flow rate, cumulative flow, flow velocity, and percentage. In terms of output, it comes standard with 4–20 mA current output, pulse output, and an RS‑485 communication interface; optional communication protocols include Modbus, HART, and Profibus‑DP, facilitating integration with PLCs, DCSs, SCADA systems, and enabling remote monitoring and data management.

V. Robust construction, easy installation and maintenance

The ZT‑EMF series sensors feature no internal obstructions or moving parts, resulting in zero additional pressure loss and a long service life. They require short straight‑pipe runs—5D upstream and 3D downstream—making them well suited to applications with limited installation space. Sensor electrodes and liner materials can be customized to match the characteristics of the process fluid: electrode options include 316L stainless steel, Hastelloy C, titanium, tantalum, and others; liner materials comprise polytetrafluoroethylene (PTFE), chloroprene rubber (CR), polyurethane (PU), and more, suitable for acids, alkalis, saline solutions, as well as wastewater, slurry, and other media. Connection types include flanged, clamp‑on, and collet‑type configurations, with custom‑designed quick‑connect fittings and other specialized interfaces available upon request.
