Series 3000 MVD Transmitters and Controllers
Operation Mode – Batch
Example 1
Batch control configuration:
• No. of Stages = 2
• Configure Presets By = % of Target
Preset configuration:
• Target = 100 liters
• Open Primary = 0%
• m (Open Secondary) = 30%
• n (Close Primary) = 70%
Operator actions:
• None (see the first sequence in Figure 18-5)
As a result:
• At the beginning of the batch run, the primary valve opens and flow
starts.
• When the flowmeter has measured 30 liters, the secondary valve
opens.
• When the flowmeter has measured 70 liters, the primary valve
closes.
• When the flowmeter has measured 100 liters, the secondary valve
closes.
Example 2
Batch control configuration:
• No. of Stages = 2
• Configure Presets By = % of Target
Preset configuration:
• Target = 100 liters
• Open Primary = 0%
• m (Open Secondary) = 30%
• n (Close Primary) = 70%
Operator actions:
• STOP/RESUME occurred after 20 liters had been measured (20%
of target; x = 20%) (see the second sequence in Figure 18-5)
As a result:
• At the beginning of the batch run, the primary valve opens and flow
starts.
• When the flowmeter has measured 50 liters (30 + 20, or m + x), the
secondary valve opens.
• When the flowmeter has measured 70 liters, the primary valve
closes.
• When the flowmeter has measured 100 liters, the secondary valve
closes.
