Introduction - GE UTX878 Ultrasonic User Manual

Introduction

Programming Site Data
The Model UTX878 flow transmitter includes a User Program that
provides access to the various programmable features of the
instrument.This chapter describes step-by-step programming
instructions using the internal keypad, shown below in Figure 2-1.

Refer to the appropriate section for a discussion of the following
PROG menu options:
•
Status - activate or deactivate one or both channels/paths
Note: The UTX878 can use two channels or paths to make more
accurate flow measurement by averaging, subtracting or
adding the channels/paths together.
•
Transducer - enter data for preprogrammed or special clamp-on
transducers
•
Pipe - enter pipe parameters
•
Fluid - enter fluid type and Reynolds Correction data
•
Path - enter number of traverses and transducer spacing (for
clamp-on transducers)
•
Signal - entering signal parameters such as Delta-T offset, zero
cutoff and velocity averaging
•
K Factor - entering the Meter Correction (K) Factor as a single
value or as a table of values
•
Error Limits - entering minimum and maximum signal, velocity,
amplitude and soundspeed.
To measure flow rate with the UTX878 you must, at a minimum,
activate the channel/path(s), and enter transducer, pipe and fluid
parameters. As a programming aid, Appendix A includes a complete
set of menu maps for the user program, and Figure A-1 on page A-1
offers the menu map for the PROG menu.
Note: This manual will describe only the programming of Channel
1. To program Channel 2 of a 2-channel/path meter, simply
repeat the same procedures presented for Channel 1.
