Accuracy: ±2% full scale @ 20 to 30 °C liquid temperature,

±4% full scale otherwise

Measurement Modes: Current Flow

Total Flow

Fluid Viscosity: 0 to 200 centipoises

Fluid Temperature Range: 0 to 50 °C

Acceptable Tubing: All types

Tubing Connector Size: Inside diameter of nominal 1/8” ID (3.2 mm)

Wetted Parts: Nylon and PharMed® Tubing

CAUTION: Prior to use, a chemical resistance chart should be used to insure

that wetted parts will not be affected by the chemical being pumped.

BUTTON FUNCTIONS

Toggles the LCD display between showing the Current Flow rate and

Total Flow.

Selects the unit of measure to be displayed. Also used when setting

the K-Factor.

Zeros the Total Flow. When the ﬂ ow rate is less than 10 mL/min, zeros

the current ﬂ ow rate. Also used when setting the K-Factor

Turns the unit On/Off. Also used when setting the K-Factor.

OPERATION

1. Plug the power supply into the unit.

2. Plug the power supply into an electrical outlet.

3. Remove red covers from the inlet and outlet barbed pump ﬁ ttings.

4. Connect the incoming tubing to the Inlet barb.

5. Connect tubing to the Outlet barb.

6. Press the POWER button to turn the unit on.

7. Press the UNITS button to select the desired unit of measure to display.

8. Press the FLOW/TOAL to toggle between the Current Flow Rate and Total

Flow display.

9. Press the POWER button to turn the unit off.

SETTING THE K-FACTOR

To insure the most accurate measurement, the K-factor should be set. The

meter is calibrated by ﬂ owing know amounts of water at known temperatures

through the ﬂ ow meter. The measurement accuracy of the meter can be

affected by a difﬁ rent liquids viscosity, liquid temperature, system pressure,

tubing diameter, etc. Insert the ﬂ ow meter into your system, and zero the Total

Flow. Pump a known volume of liquid through your system. Calculate the

K-factor by dividing the known liquid volume by the Total Flow indicated by the

Flow Meter and set the K-factor accordingly.

To set the K-Factor:

1. Press the FLOW/TOTAL button to select the Total Flow mode.

2. Press the UNITS button until the K-factor is diplayed, indicated by “K=”.

3. Press the ZERO button to increment the selected digit.

4. Press the POWER button to change the digit selected.

5. With the desired K-factor set, press the TOTAL/FLOW button exit from the

K-factor setting mode.
