AI-708H-808H Intelligent Flow Totalizer
AI-708H-808H Series flow totalizers can accumulate the mass, volume or length of an object, and can provide batch control over the accumulation
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.
- Advanced computation algorithm assure enough accuracy in the application of flow measurement even if the frequency input signal is very small.
- 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.
- No panel DIN rail mounted type is also available, can be operated by computer via RS485 communication interface.
