电磁流量计
The Promag 55S is designed for non-uniform, abrasive and corrosive fluids. The sensor uses an industry-optimized liner and is rugged, suitable for the most challenging environments and metering applications, such as wastewater treatment, pulp and paper, and primary raw materials and metallurgy. The Promag 55S is equipped with a high-performance transmitter that not only measures flow reliably but also calculates the solids content with low maintenance requirements.
