The E+H Proline Promag W 300 electromagnetic flow meter is designed for demanding water and wastewater applications, and for use in hazardous areas and under harsh conditions. The flow meter features a compact, dual-compartment housing, up to three input/outputs, and accurate bidirectional measurement independent of pressure, density, temperature and viscosity.

The W 300's compact, easily accessible transmitter offers high flexibility for operation and system integration. The transmitter features access from one side, a remote display, and improved connectivity options. The W 300 transmitter does not require a proprietary communication system. It offers full access to process and diagnostic information via numerous, freely combinable I/Os and fieldbuses. Heartbeat Technology ensures compliance and process safety at all times.
