1. Introduction

The CAT3 is a versatile DC or AC powered microprocessor-based
transmitter, which provides pulse output, analog output and High/Low
flow alarm options. Up to 3 circuit boards may be installed to provide
a variety of input/output options.

The flowmeter input circuitry will accept a variety of signal types
including, low level sinusoidal, MCP/RF, pulse and contact closure.
Optional 20-point linearization is available to correct for flowmeter
non-linearities, improving overall system accuracy. The CAT3 is
compatible with all Hoffer turbine flowmeters as well as the H.O.G.
series positive displacement flowmeters.
