AI-708H FLOW TOTALIZER total station survey

 

Main Features
- Modularized structure and hardware compatible with other AI series instruments and
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 type 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 and pressure, abnormal signal detecting, and communication with
computer are available.
- Square root/no square root selectable ,8-digits accumulation value and 4-digits
momentary process value, small signal cut-out can be set at any range.
- It has perfect temperature and pressure compensation used for general gas,
saturated steam, overheat steam and liquid. The compensation calculation with the
method of table look-up has a high accuracy in the steam measurement application.
Special function can be carried out by enhancing the compensation formula upon
customers' demand.
- As used as batch controller, it has 4-bit accumulator for control and 12-bit
accumulator for total sum individually.
- With high precision current module installed, the totalizer can provide retransmission
with 14 bit output resolution and 0.2%FS output precision.
