WARNINGS AND CAUTIONS
WARNING
Consult the flow meter nameplate for specific flow meter approvals before any hazardous
location 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 F-2700 series 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
wiring 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
remove main power before disassembling any part of the mass flow meter.
CAUTION
Calibration must be performed by qualified personnel. ONICON, Incorporated, strongly
recommends 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
meter’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 F-2700 series 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)
