Product Description

The 5W4C electromagnetic flowmeter is a high-precision, reliable measuring device belonging to Endress+Hauser’s Proline Promag W400 series, engineered to deliver accurate flow measurement of conductive liquids in a wide range of industrial and municipal applications. Leveraging advanced electromagnetic induction technology, this magmeter eliminates the influence of fluid density, viscosity, temperature, and pressure on measurement results, ensuring consistent and repeatable performance even in harsh working environments.
Equipped with a high-sensitivity sensor and advanced signal processing technology, the 5W4C achieves a measurement accuracy of ±0.5% of the measured value, with a measuring range ratio of up to 1:100, capable of accurately monitoring both low and high flow rates. The sensor features a robust construction, with corrosion-resistant lining (available in PTFE, PFA, or rubber) and high-quality electrodes (stainless steel, Hastelloy, or titanium), effectively resisting abrasion, chemical erosion, and scaling from various conductive fluids, including industrial wastewater, sewage, tap water, chemical solutions, and other corrosive or non-corrosive conductive media.
One of the key advantages of the 5W4C is its flexible power supply and installation options. It supports both battery-powered and AC-powered operation, making it ideal for remote sites, underground pipelines, buried installations, and off-grid locations where external power is unavailable. The compact and lightweight design simplifies installation, requiring no straight pipe sections before or after the meter, which saves space and reduces installation costs. Additionally, the meter is IP68-rated for dust and water resistance, ensuring stable operation in wet, dusty, or harsh outdoor environments.
The 5W4C is designed with user-friendliness in mind, featuring an intuitive operation interface and easy calibration and maintenance. It provides real-time data output, including flow rate, total volume, and operating status, supporting standard signal transmission (4-20mA, HART, or Modbus) for seamless integration with industrial control systems (ICS) and data acquisition systems. This allows for remote monitoring and control, reducing on-site labor costs and improving operational efficiency.
Widely applied in water supply and drainage, sewage treatment, municipal engineering, chemical processing, food and beverage, pharmaceutical, and other industries, the 5W4C electromagnetic flowmeter offers long service life, low energy consumption, and high reliability. It is a cost-effective solution for flow monitoring in both manned and unmanned environments, helping customers optimize process control, reduce energy waste, and ensure compliance with industry standards and regulations.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
