Heat Totalizer (FX2000H)

Product overview:

FX2000H is a professional multi-function calculator for metering heat and thermal oil supply and return heat. Meter supports multiple traffic sensors, metering of water, oil and heat flow accurately.

To share:

Features:
Signal
◆ traffic signal: 4-20mA and frequency input support. 4-20mA input to provide a set of DC24V power distribution, provides a set of input frequency and a group DC12V DC24V power distribution.
◆ temperature signal: support two sets of temperature input, providing a set of DC24V power distribution, signal types 4-20mA, PT100, PT1000 optional.
◆ switch signal: Support mains failure alarm.
◆ Transmission output: 4-20mA transmitter output support.
◆ Alarm Output: Supports a group of relay contact output.
Flow Sensors
◆ Support for various throttling device [standard orifice plate (flange pressure plates, corner tapping orifice, D and D / 2 to take pressure plate), standard nozzle (ISA1932 nozzle diameter nozzle, venturi nozzle ), the standard venturi tube (casting contraction section, machining contraction section, crude iron welding contraction section)], V cone flowmeter, general differential pressure flow meter, flow meter pulse output current output meter (4-20mA vortex, electromagnetic flow meter, linear meter), pipe flowmeter, mass flowmeter.
◆ Universal Pressure Meter flow coefficient K generated by two ways: meter internal calculations and given user. When the flow coefficient K by the user to the timing, K coefficient can be segmented settings can be set up to 10 segments.
◆ differential pressure flowmeter (plates, nozzles, etc.) prescribing offers two modes: instrumentation and sensors prescribing prescribing.
◆ pulse output flow coefficient K can be segmented flow meter settings can be set up to 10 segments.
Fluid medium
◆ Support for water, liquid (oil, chemical products), oil and so on.
Trade Settlement
◆ Password: Provides supply-side, demand-side double password to ensure the safety of trade settlement.
◆ automatic conversion: Provides automatic unit conversion function, user-friendly.
◆ small flow complement: Combining real-time monitoring and recording functions, when the flow is less than the low flow threshold, according to a small flow meter automatically complement cumulative percentage calculations.
◆ overrun complement: When the actual flow rate value exceeds the set value, the instrument will automatically follow overrun complementary cumulative percentage calculations.
◆ complement blackout: power off and then re-recording instrument on the cumulative amount of loss during power.
◆ Traffic Report: simultaneous recording flow monthly, daily and period information.
◆ Heat Report: simultaneous recording calories monthly, daily and period information.
Compensation formula
◆ according to GB / T2624-2006 (ISO5167-2003) calculation throttle flowmeter discharge coefficient C, can expansion coefficient ε.
◆ gas compressibility factor Z based Redlich - Calculate hole (Redlich-Kwong) equation.
◆ calculated based on IAPWS-IF97 superheated steam, saturated steam density.
◆ natural gas physical parameters based on SY / T6143-2004 standards.
Data records
◆ also recorded instantaneous flow, for temperature, return temperature, pressure, volume and frequency transient.
◆ Record interval of 1 min / 2 min / 5 min / 10 min / 20 min / 30 min / 60 min optional.
USB backup
◆ Use USB2.0 interface to import and export configuration parameters, backup cumulative reports, historical data, alarm recording, recording power, operating log, support 4GB USB flash drives, can be directly viewed with Excel.
◆ support the FAT32 file system, Windows can automatically identify the backup data files without format conversion.
Communications Network
◆ standard serial communication interface: RS485 and RS232C, support MODBUS-RTU communication protocol.
◆ supports standard Modbus-RTU communication protocol that provides a variety of data types, such as one hundred components, engineering, cumulative amount. In addition to supporting the company's DataManagement data management software, also supports iFix, configuration king, MCGS, power control, and other general and specialized configuration software, no special drivers.
◆ Support GPRS remote communication.
