FX1100 Fiscal Flow Computer Advanced Steam Gas and Heat Energy Totalizer

Signal:
● Flow signal: Provides 4~20mA and frequency input. 4~20mA input can provide 1 set of 24VDC power distribution, and frequency signal can provide 1 set of 24VDC/12VDC optional power distribution.
● Pressure and temperature signals: Provide 4~20mA, Pt100, Pt1000, K-couple, T-couple, E-couple input, and provide 1 set of 24VDC power distribution. When used as a heat meter, provide two temperature inputs.
● Transmitter output: Instantaneous flow, instantaneous heat, differential pressure, temperature and pressure can be transmitted as 1-way 4~20mA analog output.

Flow Sensors
● Standard orifice plates, standard nozzles, standard Venturi tubes, V-cone flowmeters, general differential pressure flowmeters, pulse output flowmeters, elbow flowmeters, mass flowmeters, current output flowmeters (4-20mA vortex flowmeters, electromagnetic flowmeters, linear flowmeters) 
● The flow coefficient K of the universal differential pressure flowmeter is generated in two ways: internal calculation of the meter and given by the user. When the flow coefficient K is given by the user, the K coefficient can be set in sections, up to 10 sections.
● Differential pressure flowmeter (orifice plate, nozzle, etc.) provides two square root modes: instrument square root and sensor square root.
● The flow coefficient K of the pulse output flowmeter can be set in sections, up to 10 sections.

Applicable media
● Supports superheated steam, saturated steam, user medium, artificial gas, mixed gas, general gas, single gas, general liquid, water and other media.

Trade settlement
● Password: Provide dual passwords for suppliers and demanders to ensure the security of trade settlement.
● Automatic conversion: Provides automatic unit conversion function for user convenience.
● Small flow supplement: Combined with the real-time monitoring and recording function, when the flow value is less than the small flow threshold, the instrument automatically performs cumulative calculation according to the small flow supplement percentage.
● Over-limit compensation: When the actual flow value exceeds the set value, the instrument will automatically perform cumulative calculation according to the over-limit compensation percentage.
● Power outage compensation: record the cumulative amount of loss during the period when the instrument is powered off and then powered on again.
● Flow report: record monthly and daily flow information at the same time.
● Heat report: record monthly and daily heat information at the same time.

Compensation formula
● Calculate the outflow coefficient C and expansion coefficient ε of the throttling flowmeter according to GB/T2624-2006 (ISO5167-2003).
● The gas compressibility coefficient Z is calculated based on the Redlich-Kwong equation.
● Calculate the density of superheated steam and saturated steam according to IAPWS-IF97 formula.
● The physical properties of natural gas are in accordance with SY/T6143-2004 standard.
Real-time data logging
● Simultaneously record instantaneous quantities such as flow (heat), temperature, pressure, differential pressure (frequency), etc.
● Recording interval 1min/2min/5min/10min/20min/30min/60min optional.

Communication Network
● Standard serial communication interface: RS485.
● Support standard Modbus-RTU communication protocol, provide multiple data types, such as percentage, engineering quantity, cumulative quantity, etc. In addition to supporting our company's DataManagement data management software, it also supports general professional configuration software such as iFix, KingView, MCGS, and Force Control, without the need for dedicated drivers.
● Support GPRS remote communication.
