Flow Totalizer Item Code: AI-708 Product Description :
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.
