Can't decide on flow sensor.. ?

The top one seems like it does not require anything, it'll plug straight into your motherboard. The second one requires the frequency adapter thing.

this is from Aquatuning

"Note on sensor compatibility:
Flow rate sensors are only suited to be connected to a compatible monitoring device and CAN NOT be directly connected to e.g. the fan connector on a Mainboard, as the sensors do not output the required pulse rate as a fan does. The only way of realizing such an arrangement is the Pulsmatik (Art.No.: 71000) which can be looped in between sensor and Mainboard. For the pure cost factor we do not recommend this solution but rather the purchase and connection of a compatible fan monitor and controller"

this is from bit-tech:
" a DFM of the GMR is directly connected to the motherboard:"

that's why i'm a bit confused :confused:

EDIT; ok apparently there is two different types of the same sensor this one you can connect to MB
Thank you

The second one will not restrict the flow if the rotating element sticks. (stops)
It does require the converter board. When connected to that and then connected to a fan header either on the motherboard or a popular fan controller like Lamptron the RPM reading is number of milliliters per minute. If the readout indicates 3785 RPM you would have approximately 1 gallon/minute flowing through the sensor.

It's also important to note this device is measuring velocity which is only part of the equation. This is why there is a diameter setting on the "amplifier" component. This MUST be set as close as your tubing ID as possible to assure the reading is accurate.

Aquacomputer users can take this further and adjust the pulse counts to match flow accordingly. A bucket that holds a known amount of fluid and a stopwatch or tachymeter is all that's needed.

Koolance just released an all metal version (SS/Ni) of this as well which is stronger than the acrylic version. Of course you lose the visible aspect of the clear section.

At the flows used in PC loops restriction does not appear to be an issue. Insertion losses are similar to adding a 90 degree (elbow).

Proof of flow is much more valuable than reading pump RPM IMO.
 
The second one in my "EDIT" ..you can connect it to the MB ,i think it's the new version
"The FlowMeter AFSTL flow meter turbine can be connected directly to the Mainboard and monitored by it. It measure the flow rate in your water cooling system and shows the flow rate in rotations per minute directly via the BIOS of the system. An integrated blue indicator LED shows the voltage supply and a green LED additionally visually indicates flow an adds to the cool looks of the sensor.

The direct connection to the Mainboard allows monitoring of the flow rate just like a fan signal and display it in the BIOS or with a suitable software. FlowMeter AFSTL can be connected to the Mainboard via a standard 3-Pin connector to the Mainboard like a fan and provides a rpm signal. The pulse rate of this sensor is 100 pulses per liter added to 2000pulses base rate, hence the BIOS would show 2100rpm when a flow rate of 1 liter per minute is measured, 2200rp when a flow rate of 2liters per minute is measured."

I just ordered the one above and couldn't pass on this top ;)
