MHG heating technology.

2. Aqua Computer Flow sensor high flow 2, 2x G1/4
The Aqua Computer High Flow 2 flow sensor can be easily integrated into the cooling circuit and allows for continuous flow measurement. This flow sensor is additionally equipped with a temperature sensor to monitor the coolant temperature. The flow measurement is carried out via a rotor/impeller driven by the flowing coolant. The rotational speed is detected contactlessly through a magnetic measurement system. An optimally calibrated bearing play for each sensor ensures minimal operational noise. The sensor provides reliable measurements from approximately 35 l/h to 1000 l/h, making it ideal for most water cooling systems. Its symmetrical design allows the sensor to be integrated into the system without regard to flow direction. Additionally, the sensor can be operated in any installation position. The very low flow resistance meets the requirements of high flow systems. The High Flow 2 has significantly more compact dimensions than its predecessor. Housed in a stylish Acetal casing, the flow sensor is integrated with a very accurate and fast water temperature sensor. The stainless steel cover of the sensor is magnetically attached without screws. The connection threads are made in G1/4, allowing operation with a wide range of hose systems. Three M3 threads are integrated into the base for securing the sensor, with matching screws included in the package. Technical specifications: Dimensions: approximately 51 x 41 x 31 mm, connection thread G 1/4. A device with a flow sensor input is required to evaluate the flow signal; this is not included! Package includes: one flow sensor, one connection cable, three screws M3 x 6 mm.

3. Rs Pro Air flow sensor 10 l/min 100 l/min Type For air
The RS PRO air flow sensor is a highly advanced device for monitoring air flow rates in various applications. With a monitoring range of 10 l/min to 100 l/min, this sensor provides precise control over air flow, making it ideal for use in water cooling and other technical systems. The sensor is designed for use with hoses and can operate under pressure conditions of up to 1 MPa. Made from PMMA, a robust material, the sensor ensures high resistance and durability. Additionally, it is suitable for operating temperatures of up to 80°C, making it versatile for various applications. The sensor is an essential tool for professionals who require reliable monitoring of air flow.
- Precise monitoring of air flow rates between 10 l/min and 100 l/min
- Maximum operating pressure of 1 MPa for versatile applications
- Made from robust PMMA for high resistance
- Suitable for operating temperatures up to 80°C.

4. Bitspower Flow sensor G1/4 inch
This is a flow sensor with matte black connections featuring G1/4-inch internal threads. The coolant flows through the flow indicator, driving a black impeller. The rotational speed of the impeller serves as a flow indicator and is output via a 3-pin cable at the back.
Designed for use with an aquaero 4, 5, or 6 from aqua computer, it allows for the reading of the rotational speed, similar to a connected fan, enabling verification of whether the pressure in the water circuit is as desired. To increase the flow rate for better reading, adapters can be placed at the inlet or outlet, reducing the inner diameter to 8 mm or even 5 mm.
Technical details:
- Material: Brass, matte black
- Connections: Internal threads: 2x G1/4 inch, 3-pin rotational speed signal cable: 600 mm length
- Flow adapters: 5 mm and 8 mm (ID).

5. LogiLink SC0122
The LogiLink water detector offers maximum protection. The integrated 3V battery ensures an impressive lifespan of 10 years. A low battery status is signaled in a timely manner. Thanks to its IP65 certification, the device is protected against water jets, and the alarm is loud enough at 85 dB to warn you even in noisy environments.

6. Alphacool Icicle temperature sensor
Can be used in all exposed G1/4" threaded openings on the radiator, expansion tank, graphic card cooler or CPU cooler with the AG adapter which is included in delivery. Should an application shortly before the expansion tank be desired... No problem at all. Simply remove the AG adapter and screw a connection into the G1/4" thread on both sides and that's it. Fully potted and therefore absolutely leak-proof. Fully galvanized - no corrosion problems. Full function with any PC temperature gauge compatible with standard PC temperature gauges. Control your PC independently from the BIOS sensors: This is a double protection, similar to the well-known redundancy (double security) of the professional area.

7. Aqua Computer Passive cooler for aquaero 6, black
Mounting this passive heat sink on an aquaero 6 increases the heat dissipation from the power components and thus increases the output power of the fan ducts. In addition, the water cooler for aquaero 5 (Art. 20023) can be mounted on the passive cooler for active cooling. The passive cooler is also suitable for simultaneous mounting with the Real Time Clock (Art. 70215), but additional mounting material is included with the passive cooler.
Scope of delivery:
Aluminium heat sink for aquaero 6, black anodized
thermal pad
fixing material
Compatible to:
aquaero 6 PRO
aquaero 6 XT
Note: The aquaero 6 and the water cooler are not included in the scope of delivery! If the water cooler is used without a second or narrower elevation (very old variant), washers must be used for installation.

8. Barrow Temperature sensor G1/4
With the Barrow Temperature Sensor G1/4, you can always keep an eye on the temperatures of your system. It provides precise temperatures in real-time, allowing for a simple and effective way to control the heat in your cooling loop.
The G1/4 inch thread of the stop fitting enables you to integrate it into any component with a free G1/4 connection in the loop, such as a distro plate or a CPU or GPU water block.
It uses a classic NTC 10 kOhm thermistor, which is connected via cable to a typical 2-pin connector on compatible motherboards or controllers.
