In municipal drainage, wastewater treatment, agricultural irrigation and other fields, large fluctuations in pipeline liquid levels and complex non-full flow conditions have long been an industry pain point for flow metering. Recently, the non-full pipe electromagnetic flowmeter launched by Felix Henan Instrumentation Co., Ltd. addresses these scenarios with accurate and stable flow measurement solutions, supporting the digital and intelligent upgrade of the water and environmental protection industry.
Traditional electromagnetic flowmeters have strict requirements for full pipe conditions. Once the liquid level is insufficient or fluctuates, measurement failure and increased errors often occur, making them unable to adapt to common non-full flow conditions such as municipal sewage networks, rainwater discharge channels, and farmland irrigation culverts. Felix’s new non-full pipe electromagnetic flowmeter completely breaks this limitation through technological innovation. It combines electromagnetic flow velocity measurement with high-precision liquid level monitoring technology, equipped with an intelligent microprocessor and adaptive digital signal processing algorithm. The meter can identify the liquid level in the pipeline in real time and dynamically correct the measurement model, realizing full-condition accurate metering from low liquid level to full pipe status. It achieves industry-leading measurement accuracy, with liquid level identification error controlled within a minimal range, and stable operation even when the pipeline filling rate is only 10%.
In addition to overcoming liquid level limitations, the product offers multiple advantages:
- Anti-clogging and durable, suitable for complex media: Designed without mechanical obstructions and equipped with self-cleaning electrodes, it effectively resists interference from solid particles and fibrous impurities in sewage, avoids clogging problems, significantly reduces maintenance costs, and is perfectly suitable for complex media such as impurity-containing sewage and industrial wastewater.
- Split design for easy installation and maintenance: The sensor and converter are installed separately. The converter can remotely display multi-dimensional data such as liquid level, flow rate, velocity, and cumulative flow, supporting multiple signal outputs including 4-20mA and RS485. It can easily connect to smart water platforms to realize remote data transmission and online monitoring.
- Stable and reliable for harsh environments: The fully sealed anti-corrosion structure is IP68 certified, adapting to humid and corrosive outdoor and underground pipe gallery environments. It has a long service life and minimizes the impact of working conditions on instrument performance.
Currently, this non-full pipe electromagnetic flowmeter has been applied in multiple scenarios including municipal drainage network renovation, industrial park sewage discharge monitoring, sponge city rainwater metering, and agricultural water-saving irrigation. In municipal sewage network projects, it solves the problem of inaccurate flow statistics under non-full flow conditions in old pipelines, helping management departments accurately grasp sewage discharge volume and providing reliable data support for pipeline network operation and maintenance as well as environmental supervision. In agricultural irrigation scenarios, it realizes real-time flow monitoring of open culverts, supporting the rational allocation of water resources and promoting the development of water-saving agriculture.
As a professional manufacturer in the domestic flow instrument industry, Felix Henan Instrumentation has always focused on industry pain points and insisted on technological innovation. The launch of this non-full pipe electromagnetic flowmeter is the result of the company’s years of technical expertise in the water and environmental protection sector. It fills the gap in domestic instruments for metering under complex non-full flow conditions, breaks the technical monopoly of foreign 同类 products, and provides cost-effective high-quality options for domestic users.
Moving forward, Felix will continue to be guided by market demand, increase R&D investment, and launch more intelligent instrument products tailored to industry needs. The company aims to help China’s water environmental protection, water conservancy and irrigation industries achieve efficient and accurate flow management, contributing to green development and smart water conservancy construction.
