6.1 Overview
This section provides descriptions of analog input function block parameters and the
engineering units that are supported by the flowmeter.
6.2 Analog Input (AI) Function Block
The Analog Input (AI) Function Block processes the measurement from the Transducer Block
and makes it available to other function blocks. The output from the AI Block is in engineering
units and contains a status indicating the quality of the measurement. There is one AI Block for
each measurement performed by the transmitter.
6.2.1 Configure the AI Block
A minimum of four parameters are required to configure the AI Block:
CHANNEL
L_TYPE
XD_SCALE
OUT_SCALE
Refer to Table 6-2 for analog input function block system parameters. Refer to Table 6-3 for
supported engineering units.
CHANNEL
Select the channel that corresponds to the desired sensor measurement. Refer to Table 6-1.
Note
Channels 3 through 5 are available only on meters with the MTA option.
Table 6-1. I/O Channel Definitions
Channel Description
1 Flow
2 Signal strength
3 Electronics temperature
4 Process temperature
5 Process density
