The key questions which need to be answered before selecting a magnetic flowmeter are:
•Is the fluid conductive or water based?
•Is the fluid or slurry abrasive?
•Do you require an integral display or remote display?
•Do you require an analog output?
•What is the minimum and maximum flow rate for the flow meter?
•What is the minimum and maximum process pressure?
•What is the minimum and maximum process temperature?
•Is the fluid chemically compatible with the flow meter wetted parts?
•What is the size of the pipe?
•Is the pipe always full?
