Description |
The F28 quad timer flow switch is a protection and control device for pumps. It includes four integrated electronic timers that can be set to automatically start and stop a pump at predetermined intervals. For example, the F28 can be set to automatically pump water to a tank for a period of time, or until it is full, then stop and wait for a preset time and then repeat the process endlessly; all the while protecting the pump should it run out of water. If the pump does run out of water the F28 will automatically shut it down and can be set to simply remain off until attended to, or to automatically restart and attempt to recover flow after waiting for a settable time.
Applications |
• Loss of prime protection for pumps
• Control of constant flow systems
• Maintain pressure in pipe work
• Control of automatic tank filling systems
• Loss of prime protection for bore pumps
