Warnings and Cautions
Warning!
Consult the flow meter nameplate for specific flow meter approvals before any hazardous lo-
cation installation.
Hot tapping must be performed by a trained professional. U.S. regulations often require a hot
tap permit. The manufacturer of the hot tap equipment and/or the contractor performing the
hot tap is responsible for providing proof of such a permit.
All flow meter connections, isolation valves and fittings for cold/hot tapping must have the
same or higher pressure rating as the main pipeline.
For Series AX2300 insertion flow meter installations, an insertion tool must be used for any
installation where a flow meter is inserted under pressure greater than 50 psig.
To avoid serious injury, DO NOT loosen a compression fitting under pressure.
To avoid potential electric shock, follow National Electric Code or your local code when wir-
ing this unit to a power source. Failure to do so could result in injury or death. All AC power
connections must be in accordance with published CE directives. All wiring procedures must
be performed with the power Off.
Before attempting any flow meter repair, verify that the line is not pressurized. Always re-
move main power before disassembling any part of the mass flow meter.
Caution!
Calibration must be performed by qualified personnel. Azbil North America, Inc., strongly rec-
ommends that you return your flow meter to the factory for calibration.
In order to achieve accurate and repeatable performance, the flow meter must be installed
with the specified minimum length of straight pipe upstream and downstream of the flow me-
ter’s sensor head.
When using toxic or corrosive gases, purge the line with inert gas for a minimum of four
hours at full gas flow before installing the flow meter.
For Series AX2300 insertion flow meter installations, the sensor alignment pointer must
point downstream in the direction of flow.
The AC wire insulation temperature rating must meet or exceed 85°C (185°F)
