INSTALLATION GUIDE
Channel 2 - Control Output Configuration [FSR1 Only]
Two independent open collector transistor outputs are included with the non-BTU
flow meter. Each output can be configured independently to “Alarm” for one of the
following. See Alarm Output in Part 3 for output details.

This is the value to which the totalizer accumulates before actuating the control pulse
output and repeating the accumulation. This value includes any exponents that were
entered in the BSC MENU as TOTAL E. See Alarm Output in Part 3

Setting Zero and Calibration
The software utility contains a powerful multi-point calibration routine that can
be used to calibrate the flow meter to a primary measuring standard in a particular
installation. To initialize the three-step calibration routine, click on the Calibration
button located on the top of the Data Screen. The display shown in Figure 5.8 will
appear.

Calibration (Page 1 of 3) - Zero Flow
Set -- -0.88 -0.43 Current Delta T:
1. Make sure flow is at zero.
2. Wait for flow to stabilize.
3. Press to calibrate the zero offset .
Figure 5.8 - Calibration Page 1 of 3
The first screen (Page 1 of 3) , establishes a baseline zero flow rate measurement for
the instrument.
Because every flow meter installation is slightly different and sound waves can
travel in slightly different ways through these various installations, it is important to
remove the zero offset at zero flow to maintain the meters accuracy. A provision is
made using this entry to establish “Zero” flow and eliminate the offset.
To zero the flow meter:
1) Establish zero flow in the pipe (ensure that the pipe is full of fluid, turn off
all pumps, and close a dead-heading valve). Wait until the delta-time interval
shown in “Current Delta T” is stable (and typically very close to zero).
2) Click the Set button.
3) Click the Next button when prompted, then click the Finish button on the
calibration screen.
The zeroing process is essential in systems using the FST1, FST2, and FST3
transducer sets to ensure the best accuracy.
