Level sensing and pump coordination
The suitable sensor depends on tank geometry and process medium. Pump interlocks and limits should reflect the actual process and installed protection.

Tank and Vessel Level Control
Level control monitors material in a tank or vessel and coordinates filling, transfer or draining according to defined operating limits. Automation scope depends on the equipment, operating sequence, existing controls and process requirements. Share the machine details and desired outcome to define a suitable control approach.
Application overview
Level control monitors material in a tank or vessel and coordinates filling, transfer or draining according to defined operating limits.
Typical requirements to define
- Vessel geometry and process medium
- Level switch or transmitter type and range
- Inlet, outlet and pump or valve interfaces
- High/low alarms and overflow or dry-run protections
Example process sequence
- Check level signal validity and operating mode
- Start or stop transfer equipment at defined conditions
- Monitor high and low limits
- Alarm abnormal or contradictory signals
- Require defined checks before returning to service
