Flow input Temperature input 2: Open collector Pulse Signal output Acc. flow/Acc. heat: Relay Acc. flow/Acc. heat: Pulse Acc. flow/Acc. heat: RS485 No output Introduction The ABU series is a stand- alone heat meter & calculator designed for energy consumption measurement in heating and cooling system. The device calculates the energy consumption of the system by measuring flow volume and temperature difference. Different types of flow sensor input, including pulse and open collector can be accepted by the meter. Two output modules with multiple output functions are embedded. Output function can be selected from pulse and relay contact. Remote metering and date management can be achieved by Modbus-RTU protocol over RS485 transmission module on the device. With increasing demand on energy saving and environmental protection, our product simply fulfill customer’s satisfaction and expectation.
