Vega SI-11 pulse counter is designed for counting of pulses incoming to 4 independent inputs, further accumulating and transmitting of this information via the LoRaWAN™ protocol to the gateway through wireless communication within 860-1000 MHz frequency band. In addition, Vega SI-11 can be used as a security device - two of four inputs can be configured as security inputs. The pulse counter can be used for any utilities’ meters and industrial equipment with pulse output, including water-, electric-, and heat meters. The counter is powered by a 3400mAh soldered battery with up to 10 years life up, provided data transmitted once a day.
