1. Introduction
The CAT1 is a microprocessor based loop powered transmitter. The
transmitter accepts a low-level frequency signal on the input and
provides a 4-20mA analog output proportional to the flow rate. CAT1
is compatible with all Hoffer turbine flowmeters as well as the H.O.G.
series positive displacement flowmeters.
The CAT1-L model provides for 20-point linearization of the flow
input signal and outputs a linearized analog current. CAT1 is fully
configurable via an RS232 communications port located under the top
plate. CAT configuration software is a Windows based application
that provides the interface for entering K-factors, frequencies, the
timebase for rate measurement, and calibration of the analog output.
Configuration and remote monitoring can also be performed using any
PC based communications program (e.g., HyperTerminal) or ASCII
terminal.
The standard unit is packaged in an extruded aluminum enclosure for
wall mounting or may be mounted directly on a flowmeter using an
optional NEMA 4X or EX enclosure. An optional bracket is also
available for mounting on standard DIN rail.
This instrument is designed to conform to the EMC-Directive of the
Council of European Communities 89/336/EEC and the following
standards:
Generic Emission Standard EN 50081-1
Residential, Commercial & Light Industry Environment.
Generic Emission Standard EN 50081-2
Industrial Environment.
Generic Immunity Standard EN 50082-1
