Basic Instrumentation for Signal converter for electromagnetic inductive flow meter - Instrumentation Training

Now in below video i will tell how a signal converter gives a  standardised output from the electromagnetic flow meter.

here is the Block diagram and description of the signal converter for electromagnetic inductive flow meter.
The Signal Converter consists of five functional groups,

Functional group 1,  contains an input amplifier, and a high resolution analog to digital converter (ADC) that is controlled and monitored by microprocessor µP 01.
Functional group 2, generates a pulsed, electronically controlled direct current for the primary head coils.  This group is galvanically Isolated from all other groups.
in functional group 3, the digitalized data supplied by µP 01 are evaluated by microprocessor µP 02 in accordance with the functions, operating and primary head data set by way of the 3 keys. Microprocessor µP 02 controls With the aid of the Krohne-developed LSl circuit (KSA) the outputs that are galvanically isolated by optocouplers. The last measured value and other information are forwarded via this circuit to the alphanumeric LCD for indication.
The KSA module is also used to feed last counts to the EEPROM. In the event of a power failure, last counts are saved in EEPROM 2. In the same way as operating and functional data are permanently stored in EEPROM 1, both are retained for 10 years without auxiliary power.
Functional group 4, converts an output signal into a proportional current. This group is galvanically isolated from the other groups but not from functional group 5.
Functional group 5, consists of power drivers to allow control of electronic (EC) and electromechanical [EMC) totalizers. This group is galvanically isolated from the other groups but not from functional group 4.
Functional group 6, (option) consists of an FBA modem which allows bidirectional data transmission between the signal converter and the M I C 500 hand-held communicator. This group is electrically isolated from functional group 4 (current output) and functional group 3 by a transformer.
