Description
Scienco Products Model SEM-10 and SEM-10FT flow meters are identical in operation and
performance. The SEM-10 is intended for fixed mounting to a pump or other device that can
provide support. The SEM-10FT is designed for mounting at hose end. The female threaded
connection on the SEM-10FT should be connected to the hose and a ball valve should be
connected to the male threaded connection.
Theory of Operation
The SEM-10/SEM-10FT flow meter is a positive displacement, nutating disk, fluid metering unit.
As fluid flows through the unit, it causes the nutating disk to move which in turn causes the
rotation of a hermetically sealed magnet disk. The meter electronic assembly counts the
number of revolutions of the magnet and mathematically determines, based on the calibration
number, the quantity of liquid that has passed through the meter. The self-contained electronic
assembly features a large Liquid Crystal Display (LCD), and simple four-button operation.
Features
•Simple, one touch operation
•Large, 0.7-inch LCD Display Characters
•Choice of three calibration modes
•Large positive touch buttons

Operating Procedures
TO METER FLUID: With pump properly installed onto a pumping system meter will wake-up
automatically and begin to display Current Total as fluid is pumped.
TO DISPLAY CURRENT TOTAL: Press “ON” button.
TO RESET CURRENT TOTAL TO ZERO: Press and hold the “RESET” button for 3 seconds
while Current Total is displayed. Current Total is reset to “.00”. TO DISPLAY TOTAL-2; With
Current Amount showing, press and HOLD “TOTAL-2”. Total number will be displayed as long
as “TOTAL-2” is pressed. Once released Current Amount is shown. Note: Total-2 can not be
reset to zero.
TO DISPLAY FLOW RATE: With the meter on, press and hold the “ON” button for two
seconds. The display will read “FX.X”, with the numbers indicating flow rate in units of volume
per minute. To return to total volume dispensed, press and hold the “ON” button for two
seconds again.
Calibration Procedures
Model SEM-10/SEM-10FT Flow Meter has three calibration options, CAL-1, CAL-2, and CAL-3.
This flow meter can be calibrated in any unit desired (i.e. gallons, liters, pounds, acres, pints,
etc.). CAL-1 requires pumping 5 units of fluid. CAL-2 requires the pumping of a known quantity
of any units; this quantity is then entered into the electronics. CAL-3 allows calibration without
pumping fluid by manually changing the calibration constant.
Before performing meter calibration, turn pump on and purge pump and hose of all air. For best
results, calibrate at normal dispensing conditions, i.e. flow rate and pressure.
CAL-1 Calibration
1. Press “ON” button to wake up meter.
2. Press and hold the Reset button to zero (“.00”) the Current Total screen.
3. Press “CAL-1” to enter calibration sequence.
4. Pump liquid into a calibrated container that holds five units (gallons, liters, etc.). Note:
The display will blink as fluid is being pumped.
5. Press “CAL-1” to complete the calibration process. Note: The display will return to the
Current Total screen and should read previous total.

7
CAL-2 Calibration
1. Press “ON” button to wake up meter.
2. Press and hold the Reset button to zero (“.00”) the Current Total screen.
3. Press “CAL-1” to enter calibration mode.
4. Press “CAL-2” to enter calibration CAL-2 mode.
5. Dispense desired amount. Note: For greatest accuracy pump a minimum volume of 2.5
gallons or 9.5 liters. The minimum amount required is 0.5 gallons or 1.9 liters.
6. Press “CAL-1”. Note: The last volume entered will appear on the display. Example: If
you have previously calibrated on 30 quarts then “30.00” would appear. First time
default is “5.00”.
7. Press “UP or DOWN ARROW KEYS” to scroll in the amount actually pumped. Use the
desired units. Example: If you pump 2 gallons but you want the meter to display in
quarts, enter “8.00”.
8. Press “CAL-1” to enter amount and finish the calibration process. Note: The display
will return to the Current Total screen and should read previous total.
Note: “ERR” will be displayed if too few or too many counts have been received during the
calibration. You must record a volume between 0.5 to 20 units for a valid calibration. If
“ERR” is displayed no calibration change has taken place.
CAL-3 Calibration
1. Press “CAL-1” to enter calibration mode.
2. Press “CAL-3”. The current CAL-3 number will show.
3. Press the “UP or DOWN” ARROW KEYS”.
4. Press “CAL-1” to enter the new number.
Use of the “CAL-3” function will now automatically override any previous units of volume entered
if “CAL-2” mode had been used. The change prevents a conflict between the “CAL-2” units and
the “CAL-3” number, and will be transparent to users who do not use “CAL-2” for calibration.
A typical “CAL-3” number for water is 600. Recording “CAL-3” numbers for various products
dispensed after calibration, and resetting the meter to those numbers when the liquid is pumped
again is a convenient method to accurately and quickly measure various liquids dispensed.

Troubleshooting Guide
Problem: Meter reads high or low.
Solution: Check for the following:
•Ensure lines are full and there is no trapped air in the system before
calibrating.
•Pump may be sucking air due to low fluid level or bad pump inlet
connection.
•Calibrating at one flow rate and operating at a different rate. Or
calibrating on one less viscous fluid (water) while pumping another more
viscous fluid (30wt oil).
Problem: Meter flashes “ERR” at end of calibration procedures.
Solution: Check for the following:
•Meter Electronics is not sensing the rotation of the magnet. To verify no
rotation look at the CAL-1 or CAL-2 while fluid is being pumped through
meter, if it does not “BLINK” then the electronics is not sensing rotation.
Disassemble meter and clean out or replace the meter chamber (SEM-10
KIT).
•Volume dispensed to calibrate is too small or too large. Must dispense a
volume of at least 2.5 gallons, and no larger than 70 gallons.
Problem: No liquid will pass through the meter or the meter will not register the
flow.
Solution: Foreign material is in the metering cartridge and is obstructing flow or
preventing the nutating disk from moving freely. Remove the meter
cartridge and clean.
Problem: The meter will not power up or the display appears dim.
Solution: Replace the battery.
