Yokogawa ADMAG AXR two-wire magnetic flowmeter

Yokogawa has enhanced the ADMAG AXR two-wire magnetic flowmeter. This enhanced flowmeter has been certified for use in safety integrity level 2 (SIL2) applications and it supports the latest HART 7 protocol, eliminating the need for convertors to connect with HART-compliant control systems. HART 7 also supports and automatic alarms when the device’s settings are modified or a problem is detected by self-diagnostics.

The ADMAG AXR flowmeter uses a dual-frequency excitation method, with low-frequency excitation that ensures stable measurement of flow rates and high-frequency excitation that delivers high noise resistance, thus realising stable measurement in a wide range of fluid conditions. This high-performance two-wire flowmeter can be used in both monitoring and control applications. Its installation and maintenance costs are significantly lower because two-wire magnetic flowmeters do not require a dedicated power supply unit and use only a single pair of cables. Their low power consumption also reduces running costs. In addition, explosion-proof types suitable for installation in hazardous areas are now available for the entire range, covering bore diameters from 25 to 200 mm.
