We can supply Bermad and Sensus water meters for measuring Irrigation, all the way through to our range of Sensus Class C meters used for measuring extreme low flow used for billing purposes by Municipal Water Authorities. Some water meters emit a fluctuating magnetic field that can be detected by using a Hall effect sensor. All these sensors are available as we defined them in the previous step (step 5). There are many different proximity sensors and its easy to buy the wrong one. The HRI-Mei is a data capture device for Meistream bulk water meters. Luckily the meter provides a spinning wheel that contains a magnet. That magnet can be recognized by a proximity sensor. Its also important to make sure you buy a 5V version so you can power the sensor directly from the ESP. In case you want to store the Python script somwhere online, you can use the following command on the Pi to grab the file: To test the changes, give the Pi a reboot with command: If everything is set correct, the following line will be visible in the console after reboot: When you now hold a piece of metal within the 4mm sensor range, the led will activate, and in the console screen the following lines should be visible: The Response:ok is a confirmation that the JSON call to Homeseer is done correctly. If you want to make it really easy, you order some female Dupont cables (Banggood or AliExpress) and shrink solder seal connectors (Banggood or AliExpress). The sensor has a red LED light on top, the led will turn one when the magnet passes. qui doit inter ragit avec un rseau de communication par exemple lora, wifi etc, un autre problme, le code de calcul automatique de la consommation deau.

Theres just an analog counter. Via the MobaXterm tool its easy drag & drop. Digital pin 3 of arduino is configured as interrupt pin. Regarding the smartmeter (energy/gas) there are probably other scripts available online that will do already the trick for you and you dont have to reinvent the wheel. In the raspi-config, enable console auto login (via Boot Options Desktop/CLI Console Autologin Text console). Unfortunately the sensor cannot report the current water flow rate because the sensor can not track time while sleeping; the elapsed time between two blinks is required to calculate the current flow rate. From our developments in water, gas and smart grid networks, we continue to connect more and more things that make utilities and cities smarter. Use the TCRT5000 IR Barrier Line Track sensor. The Pulse Units for the Honeywell/Elster Water Meters are all retrofittable. A working Raspberry Pi.

The most common pulse output switch attaches to the lens of the meter's register, directly above a dial that has the magnet attached. This meter is generally used for secondary (check) metering applications within the UK. Description Features & Documents Related Sections. Flow sensors or flow indicators are flow meter devices used to measure the amount of liquid, gas or vapour that passes through them. Certain meters allow for a choice of which dial to use for the pulse output, thus determining the volume of water that is represented by a pulse. This blog is intended to provide a semi-permanent point in time snapshot and manifestation of the various thought and solutions that are in our minds, and as such anycode, solutionsand opinions/thoughts expressed within out-of-date posts may not the same, nor even similar, to those I may hold today. 2 is the child entity and will correspond to the text of S_INFO entity attached to this device (you see this in the entities), /* When you successfully locate the place for the sensor, you need to attach the sensor to the water meter. 1 - 20 gpm to 8 - 160 gpm, Flow Ranges: 1 - 20 gpm to 8 - 160 gpm, Connections: bonjour, je suis entrain de mettre en place un compteur intelligent qui doit communiqu avec la centrale et le clientje suis bloqu sur le code avec Raspberry pi. Have questions? I dont think the Pi will have issues because of this. Every time the magnet passes and LED lights up means that a full cycle has occurred. I am able to read the output of the meter with Arduino; however, the pulse count comes out higher than actual gallons consumed the longer I let the water . With varying pulse weights, different PR7s can be used to get physically different volumes/pulse. . The sensor example sketch counts the pulses from your attached sensor and converts it into liters or gallons per minute and the cummulative water volume. You can buy this board at your favorite Chinese shop or Amazon somewhere for a price between 3-10 euros. Hi Gabriela, A data sheet that tells us what kind of sensor is in the meter is necessary.
