Endress Hauser Proline Promag W 300 Electromagnetic Flowmeter 5W3B1F 5W3B1H 5W3B1Z

The Proline Promag W 300 is an electromagnetic flowmeter from Endress+Hauser, engineered as a specialist for demanding water and wastewater applications with a compact, easily accessible transmitter. Designed for reliable operation in hazardous areas and harsh conditions, it delivers high-precision measurement for industrial and municipal water and wastewater tasks.

Key Features and Benefits

  • Reliable Measurement with No Pressure Loss: The patented full-bore sensor requires no inlet or outlet runs, ensuring constant accuracy with no pressure loss due to cross-section constriction. The bidirectional measuring principle is virtually independent of pressure, density, temperature, and viscosity.

  • Flexible and Durable Design: The sensor is available with welded or lap-joint process connections and features a robust, completely welded construction for long-term operation. It complies with EN ISO 12940 corrosion protection standards for underground or underwater installation.

  • Comprehensive Transmitter Capabilities: The compact dual-compartment housing supports up to 3 I/Os, with a backlit display featuring touch control and WLAN access. A remote display version is also available.

  • Built-in Heartbeat Technology: Integrated Heartbeat Technology enables continuous process safety monitoring and compliance verification, ensuring traceable measurement according to ISO 9001 without process interruption.

  • Drinking Water Approvals: Holds international drinking water approvals including ACS, KTW/W270, NSF 61, and WRAS BS 6920.

Endress Hauser Proline Promag W 300 Electromagnetic Flowmeter 5W3B1F 5W3B1H 5W3B1Z

 

The Proline Promag W 300 is an electromagnetic flowmeter from Endress+Hauser, purpose-built as a specialist for demanding water and wastewater applications. Featuring a compact, easily accessible transmitter, this instrument is engineered for reliable measurement in hazardous areas and under harsh conditions.

The meter operates on a bidirectional measuring principle that is virtually independent of pressure, density, temperature, and viscosity, making it ideal for industrial and municipal water and wastewater tasks. Its patented full-bore sensor design eliminates pressure loss and requires no inlet or outlet runs (0 x DN), ensuring constant accuracy even in space-restricted installations directly after bends. The sensor is available with either fixed or lap-joint process connections and features a robust, completely welded construction for long-term operation.

Wetted materials are selected for durability and compliance with drinking water standards. Liner options include polyurethane, hard rubber, and PTFE, with international drinking water approvals including ACS, KTW/W270, NSF 61, and WRAS BS 6920. Electrode materials are available in 1.4435 (316L) stainless steel, Alloy C22, and Tantalum. Measurement accuracy is specified at ±0.5% of reading for standard applications, with an optional high-accuracy version at ±0.2% of reading. The nominal diameter range covers DN 25 to 2400 (1 to 90 inches), with measuring capabilities up to 263,000 m³/h.

The transmitter features a compact dual-compartment housing supporting up to 3 I/Os, with a backlit display featuring touch control and WLAN access for convenient local operation. An optional remote display is also available. Digital communication options include HART, PROFIBUS DP/PA, FOUNDATION Fieldbus, Modbus RS485, PROFINET, EtherNet/IP, and OPC-UA, enabling flexible system integration. The device is rated IP66/67 as standard, with an optional IP68 (Type 6P) enclosure for submerged installations.

Integrated Heartbeat Technology enables continuous process safety monitoring and compliance verification, supporting traceable measurement in accordance with ISO 9001 without process interruption. The device complies with EN ISO 12940 corrosion protection standards for underground or underwater installation and holds international hazardous area approvals including ATEX, IECEx, and cCSAus.
