LDB-ST1LE Batcher
3.2 Batching
Measurements:
A flowmeter measures the actual volume in a liquid line.
Calculations:
• For Flowmeters with Pulse Outputs, Volume flow is calculated using the flowmeter frequency output
and the user entered K-Factor or Linearization Table.
Output Results:
• Display Results
Flow Rate, Batch Total, Non-Resettable Total
• Pulse Output
Total
• Analog Output
Rate or Total
• Relay Outputs
Batch Total, Rate, or Alarms
Applications:
Batching and monitoring flow and total of any liquid. Batching is accomplished via relays and
datalogging is available via serial outputs.
