Endress+Hauser Promag W 400: Versatile Water Flowmeter
Broad Functionality for Water and Wastewater
The Endress+Hauser Promag W 400 is a versatile standard flowmeter engineered for the water and wastewater industry, offering a broad spectrum of functionality optimized for these demanding applications. It is available in both compact and remote versions, providing flexibility for various installation scenarios. The transmitter’s design aims to save time and costs, incorporating features that enhance usability and integration. With international approvals for custody transfer and drinking water, the Promag W 400 is ideal for a wide array of water-related measurement tasks, ensuring accuracy and compliance in critical processes.
Dedicated to Diverse Water Measurement Needs
This flowmeter is exceptionally suited for various water measurement applications, including drinking water, utility water, and both industrial and municipal wastewater. Its bidirectional measuring principle ensures reliable performance, virtually independent of pressure, density, temperature, and viscosity fluctuations. This makes the Promag W 400 an ideal choice for utilities and industries where water quality and flow consistency are paramount. The device’s robust construction and adherence to international standards underscore its suitability for these essential services.
Reliable Measurement with Zero Pressure Loss
A significant benefit of the Promag W 400 is its capability for reliable measurement with constant accuracy, even with zero inlet and outlet run distances (0 x DN). This characteristic allows for highly flexible installation, making it possible to integrate the flowmeter even in space-restricted areas without compromising performance. Furthermore, the absence of any cross-section constriction means there is no pressure loss across the device, contributing to energy efficiency and reduced operational costs in water supply and treatment systems.
Flexible Engineering and Application Fitness
The Promag W 400 facilitates flexible engineering through its sensor options, which include fixed or lap-joint process connections. This adaptability ensures it can be seamlessly integrated into a wide range of existing or new piping systems. For applications involving challenging environmental conditions, such as underground or underwater installations, the sensor features EN ISO 12944 corrosion protection. This application fitness guarantees long-term reliability and maintains measurement accuracy, even in demanding subterranean or submerged environments.
Improved Plant Availability and Safe Operation
Designed for improved plant availability, the Promag W 400 sensor complies with specific industry requirements, ensuring dependable operation. Its robust build and adherence to standards like IP68 (Type 6P enclosure) for remote sensor versions enhance its durability. Crucially, the device ensures safe operation, as there is no need to open it for basic configuration or reading thanks to the touch-controlled, backlit display. This feature not only enhances safety by minimizing exposure to potentially hazardous environments but also simplifies routine operational tasks.
Time-Saving Local Operation via Web Server
The Promag W 400 excels in providing time-saving local operation. It features an integrated web server, which eliminates the need for additional software or hardware for configuration and diagnostics. Users can access and manage device parameters through a standard web browser, streamlining commissioning, calibration, and maintenance procedures. This accessibility, coupled with WLAN access and an integrated data logger for measured value monitoring, significantly reduces downtime and enhances overall operational efficiency for water and wastewater management.
