The FX-104 type steam thermal energy accumulation meter is an instrumentbased on ARM microprocessor, which works in conjunction with various flowtransmitters and sensors to measure flow and complete the thermal energymeasurement of steam heat carrier.
It collects, displays, controls, transmits remotely, communicates and prints various signalssuch as on-site temperature and flow, forming a digital acquisition system and control system.It is particularly suitable for trade settlement and measurement management, and enables onlinemeasurement of heat transfer, thereby providing a basis for enterprise energy management,energy consumption measurement and technical economy.
The range of applicable flow meters is extensive.
Automatic conversion of flow units and automatic calculation of the flow coefficient of differential pressure flowmeters
Trade settlement function: Protocol settlement can be enabled for high/low traffic.Emergency fault-tolerant function: When the temperature and pressure signals are abnormal,compensation calculations are performed using emergency parameter values
Debugging calculation function: Supports viewing the original values of signals from eachtransmitter/sensor, supports viewing various intermediate parameters in flow and heat energycalculation, such as density, enthalpy, etc.
Audit record: Power outage record.
Alarm list: Supports recording alarm information of instantaneous or cumulative values such asflow, thermal energy, temperature, pressure, differential pressure/frequency/volume, etc
Cumulative reports: Support daily,monthly and annual reports for accumulated flow and heat energyCommunication function: Standard Modbus RTU protocol, supporting RS485 and RS232Ccommunication interfaces.
Transmission function: Supports standard current transmission output, and thesignal source channel can be selected.
