This document describes the Proline Promag W 300 PROFINET Electromagnetic flowmeter, an electromagnetic flowmeter designed for measuring the flow of liquids with a minimum conductivity of 5 µS/cm. Depending on the ordered version, it can also measure potentially explosive, flammable, poisonous, and oxidizing media.
Function Description
The device consists of a transmitter and a sensor, forming a compact mechanical unit. It operates on Faraday's law of magnetic induction to measure volume flow and electrical conductivity directly, and can calculate mass flow.
The device offers various operation options, including local operation via a display module, a computer with a web browser or operating tool (e.g., FieldCare, DeviceCare, AMS Device Manager, SIMATIC PDM), Field Xpert handheld terminals (SFX350, SFX370, SMT70), and a control system (e.g., PLC).
For system integration, the device uses PROFINET for cyclic data exchange with an automation system. It supports Analog Input, Digital Input, Diagnose Input, Analog Output, Digital Output, Totalizer, and Heartbeat Verification modules. The device master file (GSD) is in XML format (GSDML description markup language).

Usage Features
Installation:
- Preferably install in an ascending pipe, with a sufficient distance (h ≥ 2 × DN) to the next pipe elbow.
- In down pipes, install a siphon with a vent valve downstream if length h ≥ 5 m (16.4 ft) to avoid low pressure and damage.
- For partially filled pipes, a drain-type configuration is needed.
- Orientation: The sensor nameplate arrow indicates flow direction. Vertical orientation is recommended for low process temperatures, and horizontal orientation with the transmitter at the top for high process temperatures or empty pipe detection.
- Inlet and outlet runs: Observe ≥ 5 × DN upstream and ≥ 2 × DN downstream from fittings for accuracy, unless "fixed flange" design (option C) is used (then ≥ 0 × DN).
- Thermal insulation: Housing support must be free for heat dissipation. Sensor insulation may extend to the upper edge of the two sensor half-shells.
- Adapters: DIN EN 545 (double-flange reducers) can be used for larger pipes to improve accuracy with slow-moving fluids.
Electrical Connection:
- Requires a switch or power-circuit breaker for easy disconnection from mains, and additional overcurrent protection (max 10 A).
- Terminal assignment is device-specific and documented on an adhesive label.
- Device plugs are not for hazardous areas.
- Potential equalization: Ensure same electrical potential for fluid and sensor, comply with grounding concepts, and consider pipe material. Ground cables (copper wire, at least 6 mm²) are used for unlined/ungrounded metal pipes and plastic pipes/pipes with insulating liners.
- Hardware settings: Device name can be set via DIP switches (1-8) or automation system. Default IP address (192.168.1.212) can be activated via DIP switch.
- Degree of protection: Ensure housing seals are clean, fitted correctly, and all housing screws are tightened. Cables should loop down before entry ("water trap") to prevent moisture ingress.
