BT700 flow integrator user manual, introduces the technical indicators, input, output, accuracy, communication, display, power supply, storage conditions, working conditions, selection instructions and other contents of the instrument
This manual provides technical specifications, installation instructions, wiring diagrams and detailed operation procedures for the BOTA BT700 flow totalizer. It covers input signal types, output options, accuracy, power requirements, communication interfaces and environmental limits.
The document also describes how to configure parameters, set alarm limits, clear cumulative values and select flow calculation methods for various media such as steam, gas and liquids. This manual is written in Chinese.
| Supported input signals | 0‑10 mA, 4‑20 mA, 0‑20 mA, 0‑5 V, 1‑5 V, pulse frequency (1 Hz‑8 kHz), PNP/NPN switch |
|---|---|
| Output capacity | Maximum load 1000 Ω |
| Measurement accuracy | ±0.2 % full scale for flow, temperature and pressure |
| Power supply | 85‑265 V AC, 45‑55 Hz |
| Operating temperature range | -20 °C to 60 °C |
| Communication interfaces | RS485, RS232 |
In normal display mode, press the “+” and “V” keys together to reset the total cumulative value.
The instrument provides up to three isolated 24 VDC/30 mA output channels that can be assigned to upper‑limit, lower‑limit or quantitative alarms.
Long‑press the SET key for 3 seconds to enter the parameter setting state; use PLoc codes (e.g., 1008 for primary parameters) to select the level.
The device supports temperature compensation via thermocouples, RTDs and voltage inputs, and pressure compensation via 0‑5 V, 0‑10 mA, 4‑20 mA or 0‑20 mA signals.
