Example 2
Configuration:
• Flow direction = Reverse only
• mA output: 4 mA = 0 g/s; 20 mA = 100 g/s
(See the second graph in Figure 7-3.)
As a result:
• Under conditions of forward flow or zero flow, the mA output is
4mA.
• Under conditions of reverse flow, up to a flow rate of 100 g/s, the
mA output varies between 4 mA and 20 mA in proportion to the
absolute value of the flow rate.
• Under conditions of reverse flow, if the absolute value of the flow
rate equals or exceeds 100 g/s, the mA output will be proportional
to the absolute value of the flow rate up to 20.5 mA, and will be
level at 20.5 mA at higher absolute values.
Example 3
Configuration:
• Flow direction = Forward only
• mA output: 4 mA = –100 g/s; 20 mA = 100 g/s
(See the first graph in Figure 7-4.)
As a result:
• Under conditions of zero flow, the mA output is 12 mA.
• Under conditions of forward flow:
- Up to a flow rate of 100 g/s, the mA output varies between
12 mA and 20 mA in proportion to (the absolute value of) the
flow rate.
- If (the absolute value of) the flow rate equals or exceeds
100 g/s, the mA output is proportional to the flow rate up to
20.5 mA, and will be level at 20.5 mA at higher flow rates.
• Under conditions of reverse flow:
- Up to a flow rate of 100 g/s, the mA output varies between
4 mA and 12 mA in inverse proportion to the absolute value of
the flow rate.
- If the absolute value of the flow rate equals or exceeds 100 g/s,
the mA output is inversely proportional to the flow rate down to
3.8 mA, and will be level at 3.8 mA at higher absolute values.
