HAC intelligent valve
HAC intelligent valve
Built-in collection, metering, bidirectional communication, soft clock, ultra-low power consumption, disconnection detection, low cost, multi-functional integrated integration module.
Complete meter (water meter, gas meter, heat meter, etc.) pulse measurement, at the same time, the measurement data and the relevant state of the meter will be randomly or regularly sent to the concentrator, also can read the meter data through the concentrator.
Features:
l Precise pulse filtering and acquisition circuit and measurement algorithm, high precision.
l Stable, reliable and long-distance wireless data transmission.
l Ultra-low power consumption design, average power consumption ≤25uA.
l The power supply voltage detection function can warn when the battery energy is nearly exhausted.
l Anti-disconnection function after the module is started.
l Two-way communication, real-time query of the data of the acquisition module .
