The counter contains open collector input, so pulse counting can be achieved by shortcutting 2 wires between each other. The device is capable to measure pulse length and decide if the pulse is valid or not. There are different parameters configurable remotely, beside pulse length detection the user can configure sleep time or critical trigger levels for achievement of certain volume of counted pulses.
The counter has 2 inputs – based on FW can be configured for single counter or double. Some other versions are optimized for water meter sensing heads which can distinguish between forward and back ward flow. Then one input is used as counter and the other one for direction detection. The device is battery operated and battery lifetime has been optimized by selection of high-quality and ultra low power components. 5+ year between battery replacement can be expected with 6 messages per day. Enclosure is made of high-quality ABS plastic and has been designed to meet IP65. The device can be delivered in IP68 protection on demand, as for details before order.
