The 900 Series is an economic one loop microcomputer-based instrument incorporating user selectable digital and analog inputs, as well as analog and relay outputs.  Other 900 Series features include .005% high accuracy PID, batch, and dose control functions. Additionally, the 900 Series encompasses rate metering, dual totalizing, onboard data logging, easy menu navigation, multiple audio/visual alarm functions, a serial RS-232 port, LWAN (modem) communication, and a high contrast backlit LCD display.

The 900 Series have been designed to provide unattended precision multi-parameter process control, measurement, monitoring, and data communication for a variety of commercial and industrial applications.

Process control functions are programmed manually or by using local or remote serial commands. Inputs are accepted from analog or digital signal sources, and current, voltage or relay outputs are available.

Programmable set-points include quantity, high/low/average flow rates, time in service and are used to trigger the indicators, signal output, and invoke local and remote alarm reporting.

Information is accessed locally using the display, standard RS-232 serial port, or remotely using the internal or external WAN (modem) interface.

A high contrast backlit display and multicolored front panel LED's indicate quantity totalizer states, flow rate, report state, and WAN (modem) status, with a standard on-board audio indication.

Extensive built-in self test and instillation diagnostics enable quick and easy installation.

The 900 Series non-volatile memory retains accumulated and programmed information over 100 years without a backup battery, a long life lithium battery preserves clock time over 10 years.
