High accuracy Electronic meter

-Intelligent Electronic meter - LED or LCD - Support RS485 - Modularized design - High accuracy MOQ 1

AI-708H INDUSTRIAL Electronic meter

Main Features- Modularized structure and hardware compatible with other AI series instruments andmodules, which make it easy to maintain and quick delivered.

- Modularized and configurable inputs. The flow input can be 1-5V, 0-5V, 4-20mA orfrequency signal, and special user defined input specification is also available. Thetemperature input can be configured to Pt100 RTD, K, E, J type thermocouple,voltage, or current signal. The pressure input can be various voltage or currentsignal.- Abundant functions such as retransmission, high/low alarm of momentary flow,temperature and pressure, abnormal signal detecting, and communication withcomputer are available.- Square root/no square root selectable ,8-digits accumulation value and 4-digitsmomentary 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 themethod of table look-up has a high accuracy in the steam measurement application.Special function can be carried out by enhancing the compensation formula uponcustomers' demand.- As used as batch controller, it has 4-bit accumulator for control and 12-bitaccumulator for total sum individually.- With high precision current module installed, the totalizer can provide retransmissionwith 14 bit output resolution and 0.2%FS output precision.
