FloWater Refill Stations hold seven gallons of purified water at all times (available on-demand). Through attention to detail and high-end features, FloWater’s water purifier system exceeds industry standards. I really hope some of you use this in your projects. FloWater’s Water Refill Station technology is unmatched by any other electric water delivery system. I have tested this setup on another pump (Thermaltake 500lph) and the results from it are also consistent with other results I have seen.

FLOW WATER PRO

Using a CPX Pro (jingway 1200) pump from I am getting an output of about 400lph on average which is consistent with testing from other independent testing labs. I am pumping a cooling fluid mixture through it that is similar to common automotive antifreeze so its slightly thicker than water. The flow meter is silent wen in operation and from what I can tell, does not introduce any noticeable restriction in flow. Pulse frequency (Hz) in Horizontal Test= 7.5Q, Q is flow rate in L/min. The signal is a simple square wave so its quite easy to log and convert into liters per minute using the following formula. It's a typical magnetic flow meter which outputs an electrical pulse with every revolution. The flow meter is from and cost $9.50 USD. Yes the $1.89 was what the solid brass G1/2 barbed fittings cost. I hope this helps someone out! Thank's to Seeed Studio for hooking me up with a sensor so I could develop this tutorial.

FLOW WATER CODE

Code adapted by Charles Gantt from PC Fan RPM code written by Crenn http:/ reading liquid flow rate using Seeeduino and Water Flow Sensor from High capacity FloWater Refill Stations hold seven gallons of purified water at all times (available on-demand). Once it is uploaded and you have some fluid flowing through the Water Flow Sensor, you can open the serial monitor and it will display the flow rate, refreshing every second. Through attention to detail and high-end features, FloWater’s water purifier system exceeds industry standards. Once you have it wired up you will need to upload the following code to your Seeeduino.

FLOW WATER HOW TO

Here is a fritzing diagram I made to show you how to wire it all up. The yellow wire will need to be connected to a 10k pull up resistor.and then to pin 2 on the Seeeduino. There are 3 wires: Black, Red, and Yellow. Wiring up the Water Flow Sensor is pretty simple. The threads are simple G1/2 so finding barbed ends will not be that hard. By reading these pulses and implementing a little math, we can read the liquids flow rate accurate to within 3%.

FLOW (For Love of Water) Ensuring the waters of the Great Lakes Basin are healthy, public, and protected for all. It uses a simple rotating wheel that pulses a hall effect sensor. FLOW Public Trust Solutions for the Great Lakes. The flow meter I am using is the Water Flow Sensor found in the Seeed Studio Depo. The difference of the two conditions in which the variation was directly, or, as the higher power, undoubtedly represented on the one hand the condition of water in which the mere viscosity came into play, resisting the shearing stress of the layers in passing, over each other, and on the other hand the condition when the breaking up of the water into eddying motion caused the resistance to become much greater.This is part of a project I have been working on and I thought I would share it here. Colonel Beaufoy, Froude, and others, however, found that, at higher velocities, the resistance varied more nearly as the square of the velocity. This law of resistance, it should be noted, is quite contrary to that of the friction between solid bodies as investigated by General Morin. MORE than one hundred years ago, the French philosopher Coulomb caused a disc suspended by a torsion wire to oscillate in a vessel of liquid, arid lie thus ascertained that the resistance to various bodies under such circumstances, when the movement is a slow one, varies directly as the velocity of the motion.
