You have to use the 4-pin aquabus cable because otherwise the sensor has no power (5V).



You can also use the 3-pin cable but in the case the USB cables must stay attached to provide the necessary power.

No, you have to connect from aquabus(mps) to high speed aquabus (aquaero)

After some request for more information about our new products in the aquaero 5 thread I thought it would be nice to sum up all new products of the last few days into one thread.

mps – also reads the fill level and pressure
Many of your use tubes or other larger reservoirs and our tubemeter can not be used with them or only with some downsides. The new mps controller can not only read the flow, with another housing it is also able to measure the fill level or the pressure.

There are two different ways how to connect this sensor to a reservoir.

1: You connect two tubes to the sensor. The first goes into one of the lower threads on your reservoir and the second must be connected on a thread at the top (for example a filling cap).

2: You connect only one tube to the sensor and connect it to a thread on the bottom of the reservoir like in the first method. The counterpart will be another new product: a pressure equalization membrane. It will be installed at the top of the reservoir. The membrane allows gases to pass and thereby continuously equalizes the internal pressure of the water cooling loop and the ambient pressure. This way the sensor can also detect the correct fill level.

Like the flow variant this sensor is also available in different variants. We have mps pressure Delta 40, 100, 500 or 1000. The numbers indicate the maximum fill level in centimeters. So most customers will use the Delta 40 variant while the other ones are already pretty special and make only sense when you have a very huge reservoir. So, why not just use the Delta 1000 variant? The reason is the resolution of the sensor. When using the Delta 40 variant you have a lot of small steps so you can tell the fill level with an accuracy of half a millimeter. When using the Delta 1000 variant the step size is around 1 centimeter. The general tolerance is around +/- 3%.

Like the mps flow variant the pressure sensor also offers USB, aquabus, an internal and external (optional) temperature sensor and a tacho signal output. The sensor is powered by USB or aquabus. You can connect up to four of them to an aquaero 5. When connected via USB you can use as many as you want to.

The calibration of the sensor is very easy. You set a null value with the software and enter the height of the reservoir.

The sensor has M5 threads and we recommend to use a tubing size of 4mm. Please note that no water runs through this sensor so the size has no effect at all on the general flow rate.

Besides the fill level you can also measure just a single pressure value. For example you can check the pressure of the pump or measure differences between two points in your loop. The software offers a calibration function to test whatever you want. Depending on the selected variant you can measure a pressure between 40 mbar (Detla 40) and 1000 mbar (Delta 1000). Please note that the Delta 1000 variant is not able to measure a pressure difference and must be used with the pressure equalization membrane.
(A side note: if you want to tell the pressure of the pump - for most pumps the Delta 500 variant should be enough, for dual setups the Delta 1000 should be the better choice.)

This sensor is also made from Delrin and features an engraved stainless steel cover. All variants cost 37.99 EUR (31.92 EUR w/o VAT).

As said, you can not have six mps based aquabus devices. If you connect four pumps you could connect two of the normal flow sensor: #1 on the regular 3-pin connector and #2 on fan channel 1 if you change its configuration to act as a header for a flow sensor.

The aquabus is a real bus system so it does not matter how you connect everything. The maximum is 8x poweradjust 2, 4x mps based controllers (D5 pump, flow sensor, pressure sensor), 2x aquastream XT, 2x multiswitch, 1x tubemeter

It makes no sense to connect the D5 USB/aquabus to the PA2 because if you connect it via aquabus you can already control its speed directly. It is correct that you can control up to four of these pumps via aquabus. If you do not that is no space left for any other mps based modules (flow and pressure sensors).

• How long is the Aquacomputer tubemeter? specifically my reservoir its small, only 8CM tall measured from inside bottom to top, will the tube meter fit?
  
• If I wanted to use 2x tubemeter, how should I go about this? as I have 2 loops w/ 2x reservoirs I'd like to monitor.
