This instrument contains electronic components that are susceptible to damage by static electricity.
Please observe the following handling procedures during the removal, installation, or handling of the
internal circuit boards or devices.
HANDLING PROCEDURES
1.
Power to unit must be removed.
2.
Personnel must be grounded, via wrist strap or other safe, suitable means, before any printed
circuit board or other internal device is installed, removed, or adjusted.
3.
Printed circuit boards must be transported in a conductive bag or other conductive container.
Boards must not be removed from protective enclosure until the immediate time of installation.
Removed boards must be placed immediately in protective container for transport, storage, or
return to factory.
COMMENTS
This instrument is not unique in its content of EDS (electrostatic discharge) sensitive components. Most
modern electrical designs contain components that utilize metal oxide technology (NMOS, CMOS, etc.).
Experience has proven that even small amounts of static electricity can damage or destroy these devices.
Damaged components, even though they appear to function properly, exhibit early failure.
*** SPONSLER CO., INC. STRONLY RECOMMENDS THOROUGH UNDERSTANDING AND REVIEW
OF THIS MANUAL PRIOR TO INSTALLATION. 2

MODEL SP3000 MASS FLOW COMPUTER
INTRODUCTION
1.1
GENERAL DESCRIPTION
The Model SP3000 is a microprocessor based instrument designed to measure and compensate
flow in an industrial environment. Three inputs - temperature, pressure, and flow are provided
for calculating the flow at standard conditions. Special signal conditioning circuitry is included to
allow direct connection of 2, 3, or 4 wire platinum Resistance Temperature Detectors (RTDs),
voltage inputs or current loops. A high speed digital input is provided for interfacing with the
meter mounted SP714 Pulse Amplifier. A 32 terminal strip on the rear panel provides easy
connection to the instrument.
The Model SP3000 is powered by 50 or 60 Hz, 110 or 220 VAC, switch selectable, or can be
ordered for 24 VDC power.
The Model SP3000 is designed to provide continuous, on-line, compensation for true flowrate
from volumetric flow transducers. All volumetric, mass, or heat flow calculations are taken with
permission from the Flow Measurement Engineering Handbook written by R.W. Miller. Steam
(100% quality, saturated, or superheated to 850
o
F) computations are based on the 1967 ASME
Steam tables.
Operator interface is through a 16 key keypad and a 2 line by 20 character liquid crystal display.
(The Model SP3000 may also be set up entirely through the optional RS-232 port). Range
selection, input filtering characteristics, scaling factors, etc. are selected through the front panel
keypad or RS-232 interface. There is no need to disassemble the unit or set any dip switches.
Scaled digital and 4-20mA analog current outputs, that represent compensated flow, are standard
for use in remote monitoring of flow. Two form C relays provide isolated flow or
temperature/pressure alarm outputs.
There is a single precision voltage reference in the unit used for all analog measurements. A
single multi-turn potentiometer is provided for factory calibration. No field adjustments are
necessary.
1.2
FEATURES
The Model SP3000 is designed to provide accurate and low cost compensated flow
measurement for industrial applications. The instrument can be set up to display volumetric,
mass, or heat flow, as well as totalized flow, with an overall accuracy of 0.25%.
Fully programmable from the front keypad, the microprocessor-based Model SP3000 Flow
Computer provides the operator with prompts to set up the operating parameters of the
instrument.
The Flow Computer offers the following features:
* Front Panel 16 key programming keypad
* 2 line 20 character liquid crystal display
* Compensates gas & steam flowrates for
temperature and pressure
* Compensates liquid flowrates for temperature
* Direct input of 100 ohms RTD
* Can display flow and heat flowrates and totals
* Scaleable 5V output pulse
* Analog output of 4-20mA proportional to
compensated flowrate
* 12 bit input resolution for A/D conversion
* Non-volatile RAM memory
* Self diagnostics of instrument
* Supervisory lockout of keypad
* Provides 24 VDC excitation at 100mA
* English and metric engineering units selectable via
front keypad
* Flowrate and temperature/pressure alarms via two
SPDT relays
* Real time clock and calendar (not battery backed)
* Optional 16 point linearization of input signal
* Optional RS-232 communications 4
