3. OPERATION
The Model 414Q uses a low power CMOS microprocessor to perform all control
functions and calculations.
The instrument is fully programmable with all operating parameters and
calculation constants user programmable. (See Section 5 entitled "Calibration"
for information on programming.) All parameters and constants are stored in a
non-volatile memory which retains data without battery backup for a minimum of
10 years.
A block diagram of the instrument is shown below.
A DIL switch on the rear panel enables the frequency input circuit to be set to
interface with a wide range of flowmeters, including turbine flowmeters and
flowmeters with Namur type sensors.
