The premium device for water and wastewater measurement Promag W 300 was designed for reliable use in hazardous areas and under harsh conditions. Its compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology enables measurement reliability and compliant verification. The bidirectional measuring principle is virtually independent of pressure, density, temperature and viscosity. Dedicated to the measurement of industrial or municipal water and wastewater.
Specialist for demanding water and wastewater applications with a compact, easily accessible transmitter. Reliable measurement at constant accuracy with 0 x DN inlet run and no pressure loss. Dedicated to the measurement of industrial or municipal water and wastewater.
