The CYBLE NF (low-frequency) pulse transmitter has a single pulse output with monitoring of random backflows. The pulse output is active only during forward flow; reverse flow is stored in memory, and the pulse output is reactivated once the volume of reverse flow has been offset—ensuring that the remote counter and the water meter counter are in sync. This function is limited to 512 revolutions of the meter’s dial and is designed to monitor accidental reverse flows.
The CYBLE NF + VF (low-frequency + high-frequency) pulse transmitter has two pulse outputs and indicates the direction of water flow, which allows for precise monitoring of bidirectional water flow, control of two devices, etc.
