: Yokogawa Admag SE Electromagnetic Flowmeter

 

Product Line: Admag SE

Serial No: 05112B

---

 

1. General Description

 

The Yokogawa Admag SE is a robust, integral-type magnetic flowmeter designed for reliable and accurate measurement of conductive liquids. It features a dual-compartment housing, which isolates the electronics from the wiring terminals for enhanced safety and durability in harsh industrial environments.

This model is built with a highly resistant PFA lining and Hastelloy C electrodes, making it suitable for a wide range of corrosive and aggressive fluids. It provides simultaneous analog (4-20mA) and pulse outputs for process control and totalization.

 

Key Features 🎯

 

• Dual-Compartment Housing: Protects electronics during wiring and maintenance.
• High Chemical Resistance: PFA lining and Hastelloy C electrodes for corrosive media.
• Dual Outputs: Provides a 4-20mA analog output for flow rate and a pulse output for totalization.
• Wide Fluid Temperature Range: Suitable for processes from -40°C to +130°C.
• Robust Enclosure: IP67 rated for dust-tight and water-resistant performance.
• Communication: Supports HART or BRAIN communication protocol (superimposed on the 4-20mA signal).
