Type
   Technology Type       
   Your choices are...         
   Turbine Meter       Turbine meters use a pipe-mounted rotor that is perpendicular to the liquid flow. The rotor spins as the medium passes through the blades. The rotational speed is a direct function of the flow rate and can be sensed by magnetic pickup, photoelectric cell, or gears. 
   Ultrasonic Meter       Ultrasonic meters use sound waves to determine flow rates. They can be either Doppler effect meters or time-of-flight meters.  Doppler effect meters measure the frequency shifts caused by fluid flow. The frequency shift is proportional to the fluid's velocity. For Doppler meters to work properly for a liquid, particles must be present (measuring "pure" liquids is not possible).  Time-of-flight meters use the speed of the signal traveling between two transducers that increase or decreases with the direction of transmission and the velocity of the fluid being measured.  For liquids, ultrasonic flow meters work best with a less than 10% by volume content of suspended solids or air gaps. 
   Other       Any unlisted, proprietary, or specialized meter type.

   Process Media Type       
   Your choices are...         
   Gas       Devices measure the flow of gases. 
   Liquid       Devices measure the flow of liquids. 
   Steam       Devices can accommodate mixed-phase materials such as steam.

Mounting
   Mounting       
   Your choices are...         
   Hand-held or Portable       Portable and/or applicable by hand operation. 
   In-line       In-line meters are installed directly in the process line. They have a variety of end fittings including flanges, threads, and compression fittings. Typically, in-line flow meters require a straight run of pipe for installation. 
   Insertion Type       Devices are inserted perpendicular to flow path. They usually require a threaded hole in the process pipe or another means of access. 
   Non-Invasive       Non-invasive meters do not require mounting directly in the process flow and can be used in closed piping systems. Ultrasonic flow meters such as Doppler devices may use this type of mounting to read the flow through the pipe. 
   Other       Any unlisted, proprietary, or specialized mounting type.

Performance
   Temperature Range       Full required range of temperature measurement. Actual temperature range may vary somewhat from typical range guidelines associated with the various types. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Nominal Flow Rate       Liquid volumetric flow rate range is the range of flow in volume/time. This specification applies to volumetric flow sensors and meters for liquids. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Pipe Diameter       The diameter of the process pipe to be monitored. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
