Application(s): Pump Monitoring and Pump (motor) Protection

Product Used: KAYDEN Classic 800 Series Flow – Level – Interface – Temperature Switch

Description: Provide a rugged and reliable means for pump protection and monitoring.

• Shut down the pump (motor) when the (pump) inlet line is dry / empty.
• Automatically re-start the pump when the flow of the process material is restored.
• Provide an alarm when blockages occur in the pipeline.
• React to changes in the flow rate.

Problem: It is extremely difficult to find one device that can be configured for a wide variety of flow conditions and will not require frequent maintenance. To perform well in this application the flow switch must resist failures caused by:

• • Corrosion and / or “sludging”
• Vibration
• Water contamination - feed water and cooling water often contains sediment and high mineral content
• Electromagnetic interference from motors (etc).
• Difficult and/or controlled access points limit monitoring and daily maintenance
