UNITECH Instrument’s Model 1203 represents BATCH CONTROLLERS for Monitor your flow rate, keep a cumulative total, or select batch control. Models are available to accommodates virtually any need in flow monitoring and control. Choose from models that accept pulse or analog signal, and have a digital (RS-485) and analog signal output. Four-relay models available allow you to control valves, pumps, or other equipment to maintain desired flow, volume level, or dispensation. square root extraction to accommodate flow sensors that do not have linear outputs. This flow computer can easily be interfaced to PLC SCADA or DCS systems as various options like analog retransmission and RS 232/485-MODBUS or GPRS/GSM connectivity and
SCADA offers more flexibility and enables remote monitoring. display models are available with weather proof & Flame proof enclosure as an optional feature.
