Aquametrix SLT-5 Ultrasonic Flow & Level Monitor - Manual (Page 3)

Simple Installation and Calibratio n
Mount the SLT-5U non-contacting ultrasonic sensor at the top of a tank to con-
tinuously monitor level. The Sensor self-tunes to extended cable lengths so
the electronics enclosure/display can be mounted at a convenient location.
Select LEVEL or RANGE mode
It is fast and easy through the SLT-5 calibration menu. Simply follow the menu
prompts and set up the SLT-5 to display
level in your choice of measurement
units (ft, cm, gallons, liters, percent etc.)
for vertical and horizontal round tanks.
Advanced Operating System
You can control the SLT-5s response
to conditions like turbulence or splash-
ing and to reject tank agitators. The
SLT-5 automatically adjusts itself to
obtain the best signal. False echoes
are suppressed and filtered to ac-
curately display the correct level.
Pump Control and Alarms
Program separate ON and OFF
set-points for the SLT-5’s 3 built-
in control relays. Use them for pump control, pump alternation, high or low
level alarms, air temperature alarms, automated valves or annunciators.
Isolated 4-20mA Output
Ready for direct connection to PLC’s or comput-
ers and rated for 1000 ohm resistive load. Pro-
grammable offsets allow 4 and 20mA to be offset
from the instrument calibration for special control
applications.
Select FLOW mode for Open Channel applica-
tions
Calibration is easy with Menu selection of
common flumes including Parshall, Palmer
Bowlus and Leopold Lagco, and Weirs in-
cluding V-Notch and Rectangular.
Displays, Totalizes, Transmits and Control s
The SLT-5 large digital display shows the
flow rate while the 16-digit display shows
flow total. Use the SLT-5 isolated 4-20
mA output to transmit to chart record-
ers, and program the built in control relays
for flow proportionate control (for sam-
plers, chlorinators or external totalizers), and for flow/level alarms.
No Contact Sensor = No Maintenance
The SLT-5 Sensor mounts over the flume or weir, so there is no sen-
sor fouling or maintenance required. With built-in temperature com-
pensation, the SLT-5 maintains high accuracy (+0.25% of full
scale) to meet environmental monitoring requirements.
Includes Software for Custom Calibration
Run this software on your PC to determine the calibra-
tion formula for custom flumes, weirs or open channels then en-
ter the values into the SLT-5 calibration menu.
