The Enhanced Version of ADMAG AXR Series Two-wire Magnetic Flowmeters

Yokogawa Electric Corporation announces that it will release an enhanced version of the ADMAG AXR two-wire magnetic flowmeter on August 17. This enhanced flowmeter has been certified for use in safety integrity level*1 2 (SIL2) applications, as stipulated by the International Electrotechnical Commission (IEC), and it supports the latest HART 7*2 protocol.

The enhanced ADMAG AXR two-wire magnetic flowmeter exhibits a level of performance comparable to that of the ADMAG AXF four-wire magnetic flowmeter. With these two flowmeters, Yokogawa aims to take the top position in the global magnetic flowmeter market.

Development Background

Magnetic flowmeters are used to measure the flow rates of water, chemicals, and other conductive fluids. Two kinds of magnetic flowmeters are in general use today, the four-wire and the two-wire type. The former has two pairs of cables, one for power supply and the other for signal output, and achieves high accuracy and performance; the latter has a single pair of cables for both signal output and power supply, and achieves excellent cost performance. First introduced to the market in 2009 and installed in large numbers worldwide, our ADMAG AXR two-wire magnetic flowmeters compare favorably to 4-wire devices in terms of measurement accuracy and low noise characteristics.

To meet our customers’ needs for safer plant operations, Yokogawa has enhanced the ADMAG AXR magnetic flowmeters by providing the following features.

Product Features
1.SIL2 certification
 The enhanced ADMAG AXR has been certified for use in SIL2 applications typically encountered in the oil, petrochemicals, 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.

2.HART 7 support
 In addition to HART 5, the new ADMAG AXR supports HART 7, the latest HART protocol, eliminating the need for convertors 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.
