Low and High Flow Calibration

Low Flow Reference

The flow-rate calibration correlates the flow signal to the rate the material is moving. For mass flow using a

flow meter this is achieved by stopping the flow and calibrating the minimum flow rate and then running the

pump/or flow at full speed and calibrating the maximum flow rate.

PROCEDURE:

For flow meters providing a voltage or current signal to the X96S.

The flow must be stopped or running at the lowest speed during the Low Reference.

Using the Ronan local display or HART communicator find the Main Menu;

Scroll down until you reach and highlight Calibration.

Access Calibration by pressing the right arrow key.

Scroll down until you reach and highlight Cal Flow Rate.

Access the Cal Flow Rate by pressing the right arrow key.

Scroll down until you reach and highlight Low Reference.

Access the Low Flow Rate Cal by pressing the right arrow key.

Press the F4 key (OK) to the prompt ‘Warning – Remove loop from automatic control

before doing the reference procedure’.

Wait until the prompt changes from

‘Performing Calibrate procedure’ … (You will also see a timer counting down)

Once the timer reaches zero you will see ‘Low Reference Flowrate Counts = ‘value”

Press OK to accept or Abort to Cancel calibration.’

Press the F4 key (OK).

Scroll down until you reach and highlight Low FlowRate 0.0000 gal/min. (Note 0.000 value and units may

very depending on the what value and units were selected.) (Note: You must access the Low FlowRate

and either change or acknowledge the value to complete the reference.)

Access Low FlowRate 0.0000 by pressing the right arrow key.

Use the arrow keys to select and change the display value to the correct speed. Once the displayed value is

correct, press the F4 key (Enter). ). The Low Reference is complete.

You must proceed to High FlowRate Calibration to complete the calibration.

For an illustrated procedure, see the following pages.
