Dosing device for liquid pH and liquid chlorine control - DIY kit for pool from 10 to 150m³

The Beni Twin is an automatic water treatment device for dosing liquid chlorine and pH neutraliser, of high quality and at an incredible price.
Suitable for large pools up to 150m3.

The Beni Twin is designed for pool DIY enthusiasts. It is not pre-assembled on a board; only supplied as separate components. This provides more flexibility in tight pump houses and for future expansion with other equipment (see hardware compatibility below).

Since it comes with 2 rubber ends, it is very easy to install in the pump circuit (just behind the pump and before the inlet to the pool or spa).
Connect the inlet and outlet with rubber sleeves to the 50mm pipe (see diagram in the product images).
For connection to 32 or 38 mm Intex | Bestway or 2 inch thread, contact us via chat or info@zwembad.co

• LCD/Display controlled version (without WiFi)
• WiFiPOOL app controlled version (without LCD/Display)
• With or without level switch to stop dosing when acid or chlorine container is empty

Since 2025, the flow switch has been standard to prevent damage due to power failure.

After installing the WiFiPOOL app (available for Android and iOS), scan the barcode on the device to connect it to your phone and WiFi network. Once all devices are connected, set the automation conditions by scanning the barcode in your manual. These are ready-made factory settings applicable to most pools.

• Thanks to a special “slow / fast dosing” option in the app, the Beni Twin WiFi is suitable for both spas and pools up to 150m³.
• You can read your pH and Redox (Chlorine) levels on your mobile phone, view graphs, and receive alarms. From now on, you can adjust your pool chemistry with your phone.
• The calibration activated by pressing a “calibration” button followed by on-screen instructions is extremely simple.

Every Pool Twin comes with a “flow switch” that stops dosing when no water flow is detected.
Level detection stops dosing of the pH neutraliser when the neutralisation tank is empty.

Once water passes through the measuring/dosing nipple, the device measures pH and Redox (chlorine) and automatically adjusts pool levels. When used correctly, you are 100% sure of clean and healthy water.

Since our recent upgrade (January 2025), the WiFiPOOL controller works both via cable and WiFi. The core of this controller is the Gen 2 chipset board, which allows you to fully control a pool (see hardware below). The biggest advantage of this innovation is that the automation, whether factory set or custom configured, is stored on the chip. If the WiFi connection is lost, your water treatment continues according to the parameters stored on the chip.

An optional Ethernet cable connection is available to guarantee connectivity. However, the main benefit is that the initial device configuration is much faster and easier.

Hardware

The core of this device is the WiFiPOOL Gen 2 circuit board, enabling full pool control. With this board, you can always measure: pH, RX (chlorine), flow, level (x3), temperature (x3), pressure and conductivity (salt content).

Additionally, 4 control devices (frequency controller, peristaltic pumps, salt electrolysis, UV lamp, automatic valve, etc.) can be connected. The circuit board has an Ethernet cable port, which can be used instead of a WiFi signal.

In summary: with this device, you systematically build a complete home automation system, without extra investment in control equipment.

Software

Connecting and configuring WiFi devices via the WiFiPOOL app is very simple and efficient. The entire automation strategy is automatically installed on the phone at installation.

To prevent blockages/leaks in the chlorine injector, we recommend using descaling agent in the liquid chlorine.
