INTELLIGENT DRY RUN PROTECTOR
When the pump become the dry-running, the DRY-MONITOR stops the pump and prevent a trouble.
Shince the monitor uses the motor current valve of the pump for control, there is no need to provide thepump or piping with any special device.
Cavitations, dry running or no-discharge operation can be prevented simply by setting the electriccorrent valve of the INTELLIGENT DRY RUN MONITOR at the point of current value of closed stateon the deischarge side instead of the normal state (specified point) of the pump.
