Details
The Aquacomputer G1/4 Flow Sensor - High Flow LT (53291) is a coolant flow sensor with two G1/4 connection threads that reads from approx. 40 l/h to 1000 l/h. It has no temperature sensor of its own, and to evaluate the flow signal it needs a device with a flow sensor input, which is not included.
Properties
- Thread
- G1/4, two connection threads
- Measuring range
- approx. 40 to 1000 l/h
- Cable
- included, with standard and miniature 3-pin connectors
- Size
- approx. 51 x 42 x 30 mm
How it measures
A rotor / impeller, driven by the coolant flowing through the sensor, is how the flow rate is measured. Its rotation speed is recorded without contact, using a magnetic measuring system. Each sensor has an optimally calibrated bearing clearance, which ensures minimal running noise. This sensor delivers reliable values from approx. 40 l/h to 1000 l/h (approximately 10 to 260 US liquid gallons per hour), and is therefore ideally suited to most water cooling systems. Its very low flow resistance meets the requirements of high flow systems.
Installation
The sensor can easily be integrated into the cooling circuit and enables continuous flow measurement. A symmetrical structure allows you to fit it without considering the direction of flow. In addition, it can be operated in any installation position, though the circuit board should face upwards for the best performance and least noise. The G1/4 threads are made for virtually any tube dimensions and thus enable operation with a wide range of hose systems. Two suitable screws with spacers in the scope of delivery are for fastening the sensor by its base.
What you need to connect it
Important: a device with a flow sensor input is required, for example the OCTO fan controller or a D5 NEXT pump. The supplied cable has bigger standard and smaller miniature 3-pin connectors to suit every Aqua Computer device. Only one device may be connected per cable; the other connector stays unused. Set the input to the sensor type "Aqua Computer high flow LT (53291)" or to a calibration value from the table below, depending on device and software version. The sibling with an integrated temperature sensor is the high flow 2 (53292).
