Bluetooth Low Energy

Wireless pulse counter - water

Efento pulse counter is used to remotely monitor water flow through a water meter in order to control the water consumption and related expenses.  You can connect it to any water meter equipped with Standard output (SO) or pulse generator. The solution is dedicated for dispersed facilities, in which control of the water consumption is impossible or expensive. Analysis of meter’s data allows you to decrease water bills and quickly detect anomalies and minimize the effects of flooding. The sensor can simultaneously work with up to three water meters. By default, each counted pulse represents one liter of flowing water (l). Data is presented in the form of water flow (in liters per minute) or in the form of water consumption over a selected period of time (in m³).

You can use a free mobile application to configure the device and read the data from its memory. If you add Efento Gateway, you can build a remote monitoring system.

  • Pulse counter simultaneously works with up to 3 device with a standard output (SO)
  • Measurement period: 1 minute – 10 days (configurable by the user)
  • Battery ensures up to 5 years of maintenance-free operation
  • Add Efento Gateway and Efento Cloud to build a real time monitoring system.  The maximum distance between the sensor and the Gateway is 100 m in the open space and 20 – 30 m in the buildings
  • Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
  • The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten

Efento x IoT Creators.
Efento NB-IoT sensors have been successfully integrated with Deutsche Telekom’s platform iotcreators.com. How does it work? Set up an account at iotcreators.com -> Get a SIM card -> configure Efento sensor -> receive sensor’s messages to your server over REST.
New battery life time tool and protocol tool.
We have recently deployed a new set of tools that allow you to simulate the battery life time of Efento NB-IoT sensors depending on their settings and encode/decode protobuf messages sent by the sensors.
Efento on GitHub.
We have launched a GitHub profile, which contains code examples, tutorials on how to integrate Efento’s products into your solutions and useful tools. We will be regularly adding new tools and examples, so don’t forget to follow us!
“How warm is the water?”
This is one of the most common questions you can hear during Swedish summer. Learn how the municipality of Lerum, Sweden uses NB-IoT sensors to monitor and publish on the website current temperatures of water in the lakes.
