SECTION 2.0 INSTALLATION
2.1 INSTALLATION OVERVIEW
ONICON F-1500 Insertion Turbine Flow Meter installations are simple and straightforward. After
reviewing the installation requirements given below, see page 24 for installation instructions.
Wiring instructions begin on page 38.
2.1.1 Flow Meter Installation Requirements
WARNING
Consult the flow meter nameplate for specific flow meter approvals before any
hazardous location installation.
!
Before installing the flow meter, verify the installation site allows for these considerations:
1. Line pressure and temperature will not exceed the flow meter rating.
2. The location meets the required minimum number of pipe diameters upstream and
downstream of the sensor head as illustrated in Figure 4.
3. Safe and convenient access with adequate overhead clearance for maintenance purposes.
4. Verify that the cable entry into the instrument meets the specific standard required for
hazardous area installations.
5. For remote installations, verify the supplied cable length is sufficient to connect the flow
meter sensor to the remote electronics.
Also, before installation, check your flow system for anomalies such as:
• Leaks
• Valves or restrictions in the flow path that could create disturbances in the flow
profile that might cause unexpected flow rate indications
• Avoid areas where high RF, EMI, or other electrical interference may be present.
Devices such as VFD’s (variable frequency drives), large AC motors, etc
2.1.2 Unobstructed Flow Requirements
Select an installation site that will minimize possible distortion in the flow profile. Valves,
elbows, control valves and other piping components may cause flow disturbances. Check
your specific piping condition against the examples shown below. In order to achieve
accurate and repeatable performance, install the flow meter using the recommended number
of straight run pipe diameters upstream and downstream of the sensor.
Note: For liquid applications in vertical pipes, avoid installing with flow in the downward
direction because the pipe may not be full at all points. Choose to install the meter with flow
in the upward direction, if possible.
