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).

Efento NB-IoT pulse counters transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Pulse counters are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT pulse counters can be integrated with any cloud platform.
