Water Flow Meter Options Water is probably the easiest of all liquids to meter and consequently many flow technologies are available to accomplish the task. They operate as NPN "sinking" or PNP "sourcing." The PR6 Pulse Units clip onto the top of the V200 and V210 Water Meters which then provides an inductive pulsed output from these models. This mode requires constant power so you will need to connect the sensor to an electrical outlet. Learn more. The HYDRODIGIT-S1 is a single jet water meter with a digital display across 8 digits and inductive transmission. If you aim it at the fastest turning hand on your meter, you can detect pulses or a rate. * The sensors forms a self healing radio network with optional repeaters. However if you have an older power meter without a pulse output, then you might be able to use one of the options below to sense your water consumption. The water meter has a spinning permanent magnet and in principle this can trigger a reed switch and generate pulses for accumulation by the RTC. Can the raspberry allow a 5V in signal? Each pulse that is output by a meter represents a predetermined volume of water passing through that meter. The V110 model is particularly suitable for incorporation in energy management systems. (Only 2 and 3 generates interrupt! In this card, you can also click show more. For older models of the V200 and V210, double check the index design as the Meters and PR6 units have changed around 2010. Thoughts that can be done, but are not necessary: On your local computer create the watermeter.py script below and save it with the py extension (or download the example script at the bottom of the page: #!/usr/bin/env python Every time the magnet passes and LED lights up means that a full cycle has occurred. Wire colors can be slightly different, Ive seen both orange and pink be used for ground. Do more with your infrastructure. Example meter A100C BS Single Phase Meter What is a pulse? This filters outliers. 2, or even 10, Wh per pulse. Test this url in your bowser to see if the createdevent is increasing the counter. service: notify.mysensors Explore your potential to monitor and optimize your entire water cycle. Watersavers supplies a standard range of pulse water meters in sizes from 1/2" up to 4" BSP. This filters outliers. *. 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. See the Helix 4000 Specification Sheet for more information on what each PR7 will transmit. Only water meters contained within this document are available for selection. The Cyble Sensor is completely compatible with all Itron water meters equipped with the Cyble target. For the A100c meter each pulse represents a 1000th of a KWhr of 1Whr of energy passing through the meter. The meter coefficient of each sensor is filled in the verification certificate by the manufacturer. Via the MobaXterm tool its easy drag & drop. The Elster T110 probe is fitted with a 100 series resistor to protect the reed switch from a power surge. I already covered the power usage in a previous post, so this will describe my setup to monitor our water usage. Before we can show the measurements in Home Assistant we need to add a utility meter sensor to Home Assistant. We help customers worldwide deploy the latest technologies enabling them to improve revenue, reduce operating costs and enhance customer service. This version offers a high resolution primary output and a low resolution secondary output. 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), /* // Sometimes we get interrupt on RISING, 500000 = 0.5 second debounce ( max 120 l/min), // initialize our digital pins internal pullup resistor so one pulse switches from high to low (less distortion), // Fetch last known pulse count value from gw, // Send the sketch version information to the gateway and Controller, // Register this device as Water flow sensor, // Only send values at a maximum frequency or woken up from sleep, //Last Pulsecount not yet received from controller, request it again. // Max flow (l/min) value to report. Adjust the trimpot so it just triggered when the disk is underneath. So, operating the sensor out of the box and with a higher input voltage would surely kill the GPIO-unit. In these reports you can filter down on selected times and get more insights. He is always prepared to assist with the various products available from Precision Meters.". Please contact me if you have any questions. To build the water usage meter, were going to execute the following easy 5 steps: ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems like Home Assistant. Flow range from 39.37 litres/hr - 12.5 m3/hr. Hi Gabriela, Ive read somewhere on the internet that the sensor can operate without issues when its connected to a 3.3v source, despite the sensor is made for 5v input, so I did the same. import urllib2 If the sensor is just hanging in the air, it is counting from time to time (Im not sure if the led is flasing at that moment, because it isnt counting when Im looking to the sensor), very weird. The ethernet-cable runs in a cabel channel with other power-lines. Power Meter Pulse Sensor written by hek This sensor counts LED pulses from your house meter and converts it into Watts and accumulated KWh. Our HRI-Mei sensor reading device is a data interface for pulse output for industrial water meters.

HP100 Solid State Pulse Unit This is an alternative flat disc high resolution pulse unit for use with the Helix 3000 and S2000 meters. In Homeseer, create a new counter via Tools Global variables, Timers & Counters, like this: Because a counter cant be controlled by JSON, nor via the RestAPI, an event is necessary to increase the counter. Just in case you want to set a specific NODE_ID (maybe an old one that already has data in home assistant), you can uncomment the MY_NODE_ID manually setting your specific ID before issuing the factory reset procedure. / Affiliations
The opinions expressed here represent my own and not those of my employer. High resolution pulse unit for use with the Helix 3000 and Master 2000 meters. All set, the sensor is placed, and its time to expose the measurement values and send them over to Home Assistant. Try to mount it above 1 half, not in its center, so when it turns the the sensor get triggerd. 1/2" to 1 1/2" NPT, Flow Ranges: Use Git or checkout with SVN using the web URL. Wired M-BUS module for pre-equipped multi jet water meters mod. You will supply a total value of usage and the sensor will track the delta (difference) of the total between the period.
