Wireless m-bus pulse counter is intended to count pulses from different devices - in most of the cases watermeters. Pulse inputs are designed for so called 'dry' contacts (reed-switch) or open collector output. Our pulse counter has two separate inputs and can count pulses with maximum frequency of 20 Hz. The pulse values are then sent in the air as T1 wireless m-bus telegram. Transmission period is fixed to 1 minute and is calculated due to battery capacity. Device operates on battery and has minimum lifetime of 10+1 years. User can set with our software RF power, pulse constant, initial vlaue for each input and AES-128 encryption key to encrypt the teelgram. Enclosure is for wall-mounting and with IP54 class of protection.
