 1.
What medium is to be measured?
2.
Will meter indications be used for process control or energy
accounting?
3.
What physical measurement will be used to determine the flow rate?
4.
What are accuracy requirements?
5.
Are physical space limitations a factor in mounting the meter and
any associated equipment?
Are there any environmental conditions at meter site that would
6.
limit meter selection?
7.
Can the media flow be turned off for meter installation or must it
be a hot insertion?
8.
Must meter maintenance be accomplished with the line hot?
What range of flow must be measured currently and what is predicted
9.
flow in the future?
Will data be obtained by direct reading or remote monitoring? If
10.
direct reading, is remote monitoring contemplated in future?
Ensure meter is compatible.
11.
Is the media flow steady, intermittent, or pulsating? Is there a
full pipe flow?
Can a portable meter be used that will provide adequate
12 l
measurements and what are the cost advantages?
13.
Identify potential meter selections that meet the requirements
listed.
Contact several manufacturers for recommendations.
14.
Ensure such recommendations allow comparisons between various
15.
candidates pertaining to purchase and installation costs,
operational limitations , maintenance requirements, training
requirements, costs related to operation of the meter in the media
(pressure drop), and all other factors important to the specific
installation being evaluated.
