Voiceover / Video Transcript from Old Water Flow Meter Video:
Hello, this is Edward from Valarm. In this video you’ll see how to do remote water flow monitoring with Valarm. This is a McCrometer E7000 water flow rate sensor. It outputs 4-20mA, an industry standard for sensors. The output is linear with flowrate and since it uses a 2-wire 4-20 mA signal, the sensor readings can travel up to a mile, around 5000 feet or 1.5 kilometers.
Inside the junction box on the water flow sensor you’ll see 2 screws where you will connect a Valarm compatible Yocto – 4-20mA sensor adapter. Here I’ve matched up the red and black connections to the 4-20mA sensor adapter, which plugs in via USB to an Android device running the Valarm Pro app. In this setup you also see a Valarm Y cable that allows the Android device to charge at the same time as it is talking to sensors via USB OTG Host mode. You also see here the Sony Xperia U ST25 phone, one of our favorite devices for dedicated deployments!
Now for the initial configuration of Valarm with this water flow sensor we’ll go to All Settings, Yoctopuce, then 4-20 mA, all inside the Valarm Pro app. Since I’ve got everything plugged in and ready to test I’ll enable Yoctopuce sensors then click the Scan All button at the top of the 4-20mA screen. You’ll see that the sensor is properly detected and also get a current sample reading. Now I’ll emulate waterflow by spinning the drive shaft by hand, which will normally be spun by water and a propeller once it’s installed in a pipe. Now when I click scan all again you see the reported sensor values changing between a low of 4 and and high of 20 depending on how fast it’s spinning.
Now where’s the data? The Android device with the Valarm Pro app is linked to the Valarm Tools Cloud website and uploads the sensor data to http://tools.valarm.net. You can view your real-time sensor data on Valarm Tools Cloud from any device with a web browser. Here you see that the water flow data we just collected was all geotagged with latitude, longitude coordinates and we can also see where the sensor readings happened on a map. Here’s a tabular view of the Valarm data collected at regular time intervals. You can download this time-stamped data with one click in CSV or KML format. You can also graph the sensor values and see exactly when certain values like highs or lows were hit. To download a CSV file with your sensor data just click the Download CSV button and then you can do further analysis, statistics, and decision-making with your sensor data in applications like Excel, Matlab, SPSS, SAS, or Esri ArcGIS.
