• What is the minimum and maximum process pressure?
• What is the minimum and maximum process temperature?
• Do you require rate measurement and/or totalization from the flow meter?
• If the liquid is not water, what viscosity is the liquid?
• Do you require a local display on the flow meter or do you need an electronic signal output?
• Is the fluid chemically compatible with the flowmeter wetted parts?
• If this is a process application, what is the size of the pipe?
