Product Overview
The ANGJI Smart Flow Accumulator is an advanced industrial instrument designed to work seamlessly with various flow, temperature, and pressure sensors or transmitters. It provides precise measurement, display, accumulation, alarm control, analog output, and data communication for a wide range of media, including liquids, steam (saturated and superheated), natural gas, and general gases. Engineered for high reliability and versatility, it is an ideal solution for modern industrial automation and energy management.
Key Features
● Universal Input Technology:
Features a jumper-free universal input system, allowing the instrument to easily adapt to various sensor types and signal inputs (e.g., current, voltage, pulse, thermocouple, RTD) through simple parameter configuration.
● Intelligent Compensation:
Supports automatic temperature, pressure, and combined temperature-pressure compensation. It utilizes high-precision lookup tables for accurate density and enthalpy calculation of saturated and superheated steam.
● 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 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 standard RS485 communication interface with 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 24VDC transmitter power supply.
