SP3850 Flow Computer
Unit Description 1. Description
1.1 Unit Description:
The SP3850 Flow Computer satisfies the instrument requirements for
turbine and other pulse producing flowmeters in liquid and gas applications.
Multiple flow equations and instrument functions are available in a single
unit with many advanced features.
The alphanumeric display shows measured and calculated parameters
in easy to understand format. Single key direct access to measurements
and display scrolling is supported
The versatility of the SP3850 permits a wide measure of parameters
within the instrument package. The various hardware inputs and outputs
can be “soft” assigned to meet a variety of common application needs.
The user “soft selects” the usage of each input/output while configuring
the instrument.
The isolated analog output can be chosen to follow volume flow, corrected
volume flow, mass flow, temperature, pressure or density by means of a
menu selection. Most hardware features are assignable by this method.
The user can assign the standard RS-232 Serial Port for data recording,
transaction printing, or for connection to a computer or modem.
Front panel selection of fluid type is supported. Up to 10 fluids can be
stored in the unit
Linearization options include UVC, Strouhal/Roshko and 40 point
linearization tables.
A Service or Test mode is provided to assist the user during start-up
system check out by monitoring inputs and exercising outputs and printing
system setup.
