AI-708H   Multiused Flow Totalizer

 

Features:

Input  4-20mA, 0-20mA or Frequency Input 0-10KHz from DPtransmitter-Orifice plate, Vortex, MagFlow or Turbine flowmeter etc..User-friendly interface- Menu based easy programming interfacePasswordsfor configuration and user functions.6-Digit Flowdisplay using square root or linear signal processing.8-Digit Totaliser- Non volatile memory, no batteries to change or fail.Grand-Totaliserrecords flow till date. Both totalisers are retentive and can be reset only with a password.Configurable Flow units. Displays Flow, Total in units which are selectable from a list of normally used units.Alarms: A relay output is available which can be programmed for either Flow or Total, High or Low.Selectable Alarm Reset- Latching, Auto or delayed reset for easy control scheme implementation, ideal for batching or dosing applications.24V DC  Transmitter Supplywhich is built-in saves you a seperate DC power supply for field instrumentation.Graphical trendof current flow on "Trend screen" with programmable sample interval. Track deviations in flow.Isolated output 4-20ma-flow for remote monitoring.RS 485 MODBUSserial interface for connecting the flow totaliser to SCADA systems.Modularized structure compatible with AI series instruments and modulesModularized and configurable inputs. 1-5V, 0-5V, 4-20mA, Pt100 RTD, K, E, J type thermocouple, voltage, or current signalFunctions:retransmission, high/low alarm of momentary flow, temperature and pressureSquare root/no square root selectable8-digits accumulation value and 4-digits momentary process valuebatch controller, 4-bit accumulator ,12-bit accumulator for total sum individually.14 bit output resolution 0.2%FS output precision.Specification:
