Yokogawa ADMAG AXR two-wire magnetic flowmeter

Yokogawa Australia has released an upgraded version of the ADMAG AXR two-wire magnetic flowmeter.

According to the company, the two-wire flowmeter exhibits a level of performance comparable to that of the ADMAG AXF four-wire magnetic flowmeter in terms of measurement accuracy and low noise characteristics.

The ADMAG AXR has been certified for use in SIL2 applications typically encountered in the oil, petrochemical, chemical and other industries, and can be installed in areas that require functional safety. By pairing two ADMAG AXR flowmeters, SIL3 applications can be supported.

In addition to HART 5, the product supports HART 7, the latest HART protocol, eliminating the need for converters to connect with HART-compliant control systems. HART 7 also supports and enables the automatic issuance of alarms when the device’s settings are modified or a problem is detected by self-diagnostics.

The flowmeter uses the dual frequency excitation method, with low-frequency excitation that ensures stable measurement of flow rates and high-frequency excitation that delivers high noise resistance, realising stable measurement in a wide range of fluid conditions.

The device can be used in both monitoring and control applications. Its installation and maintenance costs are lower because two-wire magnetic flowmeters do not require a dedicated power supply unit and use only a single pair of cables. The low power consumption also reduces running costs.

Explosion-proof types suitable for installation in hazardous areas are now available for the entire product range, covering bore diameters from 25 to 200 mm.
