This product is an intelligent flow accumulating meter, which can be used with orifice, vortex, turbine, electromagnetic and other flow sensors. It has temperature and pressure dual compensation function, and can realize the flow measurement of steam, general gas, liquid and other media. The meter can accurately measure the following fluids: saturated steam, superheated steam, general gas and liquid.
This manual describes the features and operation of the AHTC Intelligent Flow Totalizer, a digital instrument that measures flow, pressure, and temperature using integrated micro‑processor calibration. It supports various flow sensors such as orifice plates, vortex, and magnetic types, and offers dual‑row LED display for instantaneous and cumulative flow values.
The document includes wiring information, power supply options (24 V DC or 12 V DC), communication interfaces (RS232/RS485 with MODBUS), environmental limits, and maintenance procedures. It also outlines signal input ranges for flow, pressure, and temperature, as well as configuration settings for density and temperature compensation. This manual is written in Chinese.
| Flow signal input (current) | 0–10 mA or 4–20 mA |
|---|---|
| Flow signal input (frequency) | 0.1–5000 Hz |
| Pressure signal input | 0–10 mA or 4–20 mA |
| Temperature sensor type | Pt100 or K, B thermocouple |
| Communication interfaces | RS232, RS485 (MODBUS), 9600/4800 baud |
| Display type | Dual‑row LED (CFLOW upper, SUM lower) |
It accepts both current signals (0–10 mA or 4–20 mA) and frequency signals (0.1–5000 Hz) for flow measurement.
The dual‑row LED display shows instantaneous flow (CFLOW) on the upper row and cumulative flow (SUM) on the lower row, with selectable parameters such as temperature and density.
