The pulse signal is a simple square wave so its quite easy to log and convert into liters per minute using the following formula. Digital pin 3 of arduino is configured as interrupt pin. // could happen when long wraps or false interrupt triggered. Our HRI-Mei sensor reading device is a data interface for pulse output for industrial water meters. I dont think the Pi will have issues because of this. Badger meter offers a customer porthole to the customer water usage. Luckily, my Pi survived this for nearly a year, although GPIO-input must not be more than 3.3 V. I now use a voltage divider (15k between black and blue/GND) to limit the output in non-active mode to around 3V on the GPIO-pin. This filters outliers. Add to Cart . The meter coefficient of each sensor is filled in the verification certificate by the manufacturer. This will provide you with a pulse, every pulse is equal to what has been defined by the meter. Use Git or checkout with SVN using the web URL. Make sure you find your way back to this article to follow along. Measurement parameters: flow rate, flow velocity, volume flow (forward, reserve and net) and pressure (option) Wide range of sensor styles and size: reduced bore DN40 to 600, full bore DN40 to 2400 and probe 300 to 1000 mm.

This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Are you sure you want to create this branch? I measure pretty much all my utilities, including power and city heating. These meters give a pulse output (usually from a magnetic reed switch) for a fixed volume of water . Each Be aware that there are many different water meters out there. The output from the pulse counter sensor is in pulses/min and we also know that 1000 pulses from the LED should equal 1kWh of power usage. # Example configuration entry sensor: - platform . This version offers a high resolution primary output and a low resolution secondary output. This is an alternative flat disc low resolution pulse unit for use with the Helix 3000 and S2000 meters. My watermeter.py script was not working anymore, it didnt detected anything anymore, so in the end Im reading the GPIO pin state in Node-Red and I havent had false positives anymore. Reliable, low maintenance. Besides this the values will be stored in MySQL each hour. Find the Water Consumption section and add the Water Meter Total sensor as a water data source.

The sensor can be easily stuck on to the front surface of any utility meter with an LED pulse output. For viewing the measurements in my lovelace dashboard I used a custom card called mini-graph-card, this card can be easily installed using HACS. 10 Pieces (Min. / Cookie Policy 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. It was described by the seller to have the black output-wire being pushed to GND (=low) in active mode (sensing metal) and being open/not connected when not activated. To start with, I connected the reed output of the water meter via 10k resistor to +5V, GND and D3. 6000 Series Flow Meter. In order to do that you will go to Home Assistant service call helper (in the developer tools), go in yaml mode and use these: Flow range from 39.37 litres/hr - 12.5 m3/hr. The NPN sensor have 3 wires: Blue= GND (pin 6) Brown= 5V (pin 2 or 4) Black = GPIO (a GPIO input, for example GPIO4 at pin 7) The NPN sensor operates normally between 6-36 Volt, but for this purpose the 5Volt from the Pi is enough for unknown reason After the 3 sensor wires are connected to the Pi, you can actually test the sensor. I did a lot of research and ended up with this LJ18A3-8Z/BX sensor sold on AliExpress.com . Ready to Ship. Produced in versions for cold and hot water in diameters DN15 and DN20 mm (1/2 - 3/4), this meter has a 360 rotating dial for ease of reading.
