Hanna flow switch for BL systems

Hanna flow switch for BL systems

Installing a Hanna flow switch for the BL system is the best way to prevent damage from overdosing without flow to the pool technology. If the pump breaks down = no water flow, dosing chlorine or pH minus in the pipe can cause a lot of damage to the installation. This water flow meter provides extra protection and will stop the dosing if there is no water flow in the pipe.

Assembly of the flow switch for BL systems

The water flow detector for the Hanna BL Pool Security systems is a paddle switch that detects the water flow in the water circuit. The assembly is done on the pipes with a diameter of 32 to 63 cm with a drilling saddle. You mount this PVC part ON the pipe and you can mount the flow switch at the top of the screw thread. The assembly is therefore extremely simple. If the paddle is too long, you can shorten it.

Advantages of the hanna flow switch

• Paddle is perpendicular to water flow and pivots to install properly
• There is a chlorine-resistant seal between the water and the electrical part
• Standard 1/2″ threaded mounting
• Glass fiber reinforced housing, suitable for drinking water use
• Contact : open or closed, depending on the water flow

The Hanna flow switch for BL systems is compatible with the Hanna Pool security plus dosing system and the Hanna Pool Security plus cloud dosing system and the variants with flow-through panel.
