SP3850 Flow Computer
3. Applications
3.1 Liquid Volume
Measurements:
A flowmeter measures the actual volume in a liquid line. A temperature
sensor can also be installed to correct for liquid thermal expansion (see
3.2 Corrected Volume).
Calculations:
• Volume flow is calculated using the flowmeter frequency output and the
user entered K-Factor.
Output Results:
• Display Results
Flow Rate, Resettable Total, Non-Resettable Total
• Analog Output
Rate or Total
• Pulse Output
Total
• Relay Outputs
Rate or Total Alarms
Applications:
The Flow Computer can monitor actual volume flow and total of any
liquid. Flow alarms are provided via relays and datalogging is available
via analog (4-20mA) and serial outputs.
