Specification Review

1. Main Features

AI-708/808H series flow totalizers can accumulate the mass, volume or length if an object, can provide batch control over the accumulation

  • Modularized structure and hardware compatible with other AI series instruments can modules, which make it easy to maintain and quick delivered.
  • Modularized and configurable inputs. The flow input can be 1-5V, 0-5V, 4-20mA or frequency signal, and special user defined input specification is also available. The temperature input can be configured to Pt100, RTD, K, E, J tyoe thermocouple. voltage or current signal. The pressure input can be various voltage or current signal.
  • Abundant functions such as retransmission, high/low alarm of momentary flow, temperature or pressure, abnormal signal detecting, and communication with computer are available.
  • Has perfect temperature and pressure compensation used for gas, saturated steam, overheat steam and liquid.
  • As used as batch controller, it has 4-bits accumulator for control and 12-bit accumulator for total sum individually.
  • With high precision current model installed, the totalizer can provide retransmission with 14 bit output resolution and 0.2%FS out precision.
  • No panel DIN rail mounted type is also available, can be operated by computer via RS485 commnication interface.

current: 4-20mA, 0-20mA

Two-wire retransmitter: directly connect to two wire transmitter

Pressure Input type:

DC voltage: 1-5V, 0-5V

current: 4-20mA, 0-20mA

Two-wire retransmitter: directly connect to two wire transmitter

Measurement Accuracy 

±0.2%FS, for temperature, pressure, frequency, momentary flow without temperature-pressure compensation.

Note: temperature-pressure compensation only for 808H

temperature / pressure compensation method

General gas: temperature-pressure compensation ( calculate by equation for ideal gas )

Saturated steam: temperature compensation ( absolute temperature range: 100℃-276℃ )

Saturated steam: pressure compensation ( absolute pressure range: 0.1-3.2Mpa )

Saturated steam: temperature and pressure compensation ( absolute temperature range: 150℃-590℃ , pressure range: 0.1-22Mpa)

General liquid: only use temperature compensation, PA is compensation factor.

 

Calculation Accuracy for temperature-pressure compensation 

the calculation error is less than 0.3%FS, and after the compensation, the overal  error is less than 0.5%FS

Control Outputs
