Description
Protect electrical pool equipment against operation without sufficient water flow with the Blue Lagoon Flow Switch Plus. This compact flow switch continuously monitors whether there is enough pool water flowing through the pipe and automatically switches off the connected device when the water flow stops.
This makes the Flow Switch Plus particularly suitable as additional protection for, for example, a Blue Lagoon UV-C installation. As soon as the filter pump stops or the flow becomes insufficient, the connected device is switched off. Once there is sufficient water flowing again, the device can be switched back on.
The Flow Switch Plus is suitable for devices up to 10 amperes, operates on 230 V, and, in the common Type F version, includes a 63 mm T-piece for mounting in the pool pipe. The minimum required water flow is only 1.5 m³/h, while a flow rate of up to 23 m³/h is possible. Blue Lagoon UVC
Protect your UV-C installation against insufficient flow
A UV-C lamp is designed to function while pool water is flowing through the housing. If the filter pump stops unexpectedly, a valve is set incorrectly, or the water circulation is interrupted for any other reason, you want to prevent the UV-C installation from continuing to operate.
The Blue Lagoon Flow Switch Plus offers an automatic safety feature for this.
The flow sensor is mounted in the pool pipe and detects the water flow. When there is insufficient flow, the power supply to the connected device is interrupted.
This means you do not have to rely solely on manually switching the filter pump and UV-C installation on and off simultaneously.
Automatic shutdown when the filter pump stops
A major advantage of the Flow Switch Plus is that the protection is determined by the actual water flow.
The system therefore does not just look at whether the pool pump is electrically switched on.
If, for example, the pump fails, the water flow is blocked, or there is insufficient water flowing through the pipe for any other reason, the flow sensor detects this and the connected device is switched off.
This makes the Flow Switch Plus a practical additional safeguard for the technical pool installation.
From 1.5 m³/h water flow
The 230 V version of the Blue Lagoon Flow Switch Plus has a minimum flow of 1.5 m³ per hour.
The maximum permitted flow is 23 m³/h. Blue Lagoon UVC
This allows the flow switch to be combined with a wide range of pool installations, from relatively compact private pools to installations with significantly larger filter capacities.
Suitable for devices up to 10 amperes
The Blue Lagoon Flow Switch Plus can switch electrical pool equipment up to a maximum of 10 A.
This means the device is not exclusively for use with UV-C systems. In principle, it can be applied to other electrical pool equipment that falls within the permitted electrical load and needs to be switched off as soon as the water flow stops. Blue Lagoon UVC
Always check the maximum power consumption of the device you want to switch with the Flow Switch Plus before connection.
63 mm connection
The common European 230 V Type F version comes with a special 63 mm T-piece into which the flow sensor is mounted.
This allows the sensor to be incorporated directly into an existing or new PVC pool installation.
If you have an installation with 50 mm PVC pipes, the assembly must be carried out using suitable 50 to 63 mm adapters.
Also suitable for saltwater pools
The Flow Switch Plus can also be used for pools that utilize a salt electrolysis system.
Blue Lagoon explicitly states that the system is suitable for saltwater systems. Blue Lagoon UVC
This makes the flow switch interesting for both traditional chlorine pools and pools where chlorine is generated via salt electrolysis.
IP54 protection class
The Flow Switch Plus has an IP54 rating.
The housing is thus protected against dust to an extent that does not hinder operation, and against splashing water. This does not mean, however, that the electrical control unit may be placed underwater.
Mount the electrical components in a suitable, dry, and protected location according to the installation instructions.
Easy to combine with Blue Lagoon UV-C
The most obvious application is in combination with a Blue Lagoon UV-C installation.
A possible setup of the technical installation is, for example:
Pool → filter pump → sand filter → Flow Switch / UV-C → any other equipment → pool
The exact sequence depends on the other equipment in the installation. If, for example, a heat pump, automatic pH/Redox controller, or salt electrolysis is present, the installation instructions of all manufacturers must always be taken into account.
Compact solution
The Flow Switch Plus is intentionally designed to be compact.
You therefore do not need to install a large control cabinet to create a simple flow-dependent protection.
The sensor is placed in the piping, while the electrical control unit is mounted in a suitable location near the pool technology.
Operation of the Blue Lagoon Flow Switch Plus
The operation is simple. The flow sensor is placed in the pipe of the pool installation.
When the filter pump is running and there is enough water flowing through the pipe, the sensor detects this flow. The connected device can then operate.
If the filter pump stops or the flow is lost, the position of the flow sensor changes and the connected electrical device is switched off.
This creates an automatic link between the actual water circulation and the operation of, for example, your UV-C installation.
What is included?
With the Blue Lagoon Flow Switch Plus, you receive the Flow Switch Plus control unit, flow sensor with connection cable, and the special 63 mm T-piece for mounting in the pool pipe.
The precise plug type depends on the chosen variant. For the Netherlands and Belgium, the 230 V Type F version is typically used.
Extra security for your pool technology
The Blue Lagoon Flow Switch Plus is a relatively simple extension that adds important extra protection to your pool installation. As soon as the water circulation becomes insufficient, connected equipment can be switched off automatically.
With a range of 1.5 to 23 m³/h, a maximum load of 10 A, a 230 V connection, and a 63 mm T-piece, the Flow Switch Plus is excellently suited for many private pool installations and, in particular, for securing a UV-C system.
