MG AND MG2 MODELS
The standard MG2 model utilizes an NPS 2 Schedule 10 pipe with a conventional corrugated
magnetic-ring float design for pressure ratings up to ASME Class 150. The MG can utilize an
NPS 21⁄2 Schedule 10 or Schedule 40 pipe with a concentric magnetic float design for applications
in higher vibration environments. The MG float design also provides increased internal support
for higher-pressure applications. Also available are interface floats designed so that 50% of 1
the float's length rides in the heavier of the two liquids and 50% in the lighter liquid. At least
0.2 difference in specific gravity is required. All metallic standpipes are designed in accordance
with ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, ASME B31.1 and B31.3. 2
This makes them ideal for use in all kinds of storage and pressure vessel applications, including
those in the most extreme-duty conditions. In addition, polymer versions constructed of NPS 2
Schedule 40 pipe are offered for low-pressure applications, where cost control and corrosion
resistance are required.
FEATURES AND BENEFITS
Connection versatility - A wide variety of connections are available: weld neck flanges, lap-joint flanges, weldolets, threadolets, sockolets, NPT threads and other plumbing options. Extruded tee allows for full-penetration welding on all side connections for Schedule 10 pipe.
Process compatibility - A wide variety of material or lining options to meet most process applications.
Code design - Meets the design requirements of ASME B&PV Code, Section VIII, Division 1, ASME B31.1 and B31.3. ASME 'U' Stamp and Pressure Equipment Directive 97/23/EC Certificate of Conformity available.
Remote control and indication - A wide variety of switches and transmitters are available for mounting on the standpipe

MGVB (VAPOR BYPASS) MODEL
The MultiviewTM Vapor Bypass is an innovation in magnetic level gauge design and addresses processes where flashing may occur, which can cause many other magnetic gauges to fail. When flashing occurs, the vapor build-up beneath the float cannot escape quickly enough due to the limited clearance between the float and the chamber wall. This causes the float to rocket to the top of the chamber where it is crushed or damaged. The MultiviewTM Vapor Bypass features a large chamber - a unique cage system which confines the float to one side of the chamber. This allows the maximum area for vapor to by-pass the float, ensuring proper magnetic coupling to the indicator.
FEATURES
• Larger chamber and unique internal float cage
• Magnetically interlocked flag-type indication
• Custom-weighted magnetic float
• Designed in accordance with ASME B31.3
• Easy installation
• Virtually maintenance-free
• Optional transmitter or switches
SWITCHES AND TRANSMITTER OPTIONS
Both point-level control and/or continuous level measurement are available with the MultiviewTM. These options can be ordered with your magnetic gauge or can be added to existing units.
MGS Switches provide non-intrusive, point-level control.
• MGS-314: SPDT (Form C) 5A service.
• MGS-314D: DPDT (2x Form C) 10A service.
• MGS-314L: SPDT (Form C) 1A service used with Standard MultiviewTM.
• MGS-314M: SPDT (Form C) 1A service used with TMMG.
• MGS-314P: a latching pneumatic switch.
MGT Transmitters provide continuous level indication to remote locations via a 4 to 20 mA loop-powered transmitter, HART® Protocol or FoundationTM Fieldbus.
• MGT-362: a reed switch-based unit available in integral and remote mounting styles.
• MGT-362B: an in-tank reed switch-based unit NPT mounted. Integral or remote mounting style.
• MGT-362C: an in-tank reed switch-based unit flange-mounted. Integral or remote mounting style.
• MGT-367: a magnetostrictive transmitter available with HART® Protocol or FoundationTM Fieldbus and optional local LCD push button display.
