Smart Flow Totalizer & Flow Integrating Instrument | Temp/Pressure Compensation | ANGJI Instrument
key Features
- Universal Input Technology: Features a jumper-free universal input system, allowing the smart flow totalizer to easily adapt to various sensor types and signal inputs (e.g., 4-20mA, pulse, thermocouple, RTD) through simple parameter configuration.
- Intelligent Temp/Pressure Compensation: Supports automatic temperature and pressure compensation. It utilizes high-precision lookup tables for accurate density and enthalpy calculation, making it a highly reliable flow computer for steam and gas metering.
- High-Precision Accumulation: Offers an ultra-wide accumulation range (up to 12 digits) with a resolution of up to 0.001. The accumulated total is permanently stored and can be retained for over 10 years in the event of a power failure.
- Comprehensive Display: Equipped with a large-screen, backlit LCD featuring Chinese/English display capabilities. It simultaneously shows instantaneous flow, accumulated total, temperature, pressure, density, and a real-time clock.
- Smart Control & Diagnostics: Includes small signal cut-off (0-5% adjustable) to eliminate noise during low-flow conditions. Features password-protected parameter settings, quantitative batch control, and alarm outputs.
- Data Recording & Reporting: Capable of recording historical data with adjustable intervals. Users can query daily and monthly reports, as well as power failure records, directly from the panel.
- Robust Communication: Supports a standard RS485 communication interface with the MODBUS RTU protocol for easy integration into DCS, PLC, or SCADA systems. Includes lightning protection for reliable data transmission.
- Flexible Output Options: Provides isolated 4-20mA analog output, relay alarm outputs, and a 24VDC transmitter power supply.
