Improper installation has the potential to cause injury and to damage instrument.
Periodically inspect the power cables, transducer cables, cable glands and the enclosure for
signs of damage. Inspect transducer installation and mounting hardware for loose
connections.
3.1
Selection of Installation of Locations
•
Correct location of the Fluid Bar-in the pipeline is important because disturbance in flow
produced by the pipe layout may affect the accuracy of measurement. The following
standard practices should be reviewed before selecting a mounting location.
•
Straight Run Requirements
The minimum straight length requirement between various fittings located upstream of
Fluid Bar are given in Table 1. Use of recommended straight pipe lengths of uniform
diameter ensures that the flow measurement will be made with fully developed
characteristics.
Included gate, globe, & other throttling valves that are partially opened. If the valve is full
open, use valves shown for 4 & 5. Values shown are the recommended spacing in terms of
internal diameters for normal industrial metering requirements. For laboratory of high
accuracy work, add 25% to above values.
•
Flow Conditioners
Flow conditioner may be used to reduce the length of straight pipe required in many cases.
Any flow conditioner used shall be installed in the upstream straight length between the
Fluid Bar & disturbance or fittings closest to the Fluid Bar. Unless it can be verified that the
flow conditions at the inlet of Fluid Bar shall confirm fully developed profile & are free from
swirl.
