What models of computing unit should I choose based on differences in the flow detection methods (differential pressure, vortex type)?

M Series computing units include a type that supports user-specified programs, and types that support analog memory, peak/bottom holders, moving averages, dead times, temperature/pressure compensation, and a wide range of other applications.

M Series unified signal converters are plug-in type signal conditioners for common instrumentation signals. They have an I/O signal range of 4 to 20 mA DC or 1 to 5 V DC.

M Series signal conditioners are a plug-in type that can support a wide range of applications through a versatile I/O specifications. Plug-in type construction provides easy for instrumentation planning, field wiring and maintenance. Over 30 types of signal conditioners are lined up in M Series.
