Procedure For Calibration; Operating Instructions; Maintenance; Cleaning Instructions - FILL-RITE 900 Series Installation And Operation Manual

Procedure for Calibration

1. For the most accurate calibration, install the meter in the application. Fill a container to a known volume
with the liquid to be measured.
2. If meter amount is incorrect, turn calibration screw (item 31) counterclockwise for less liquid, or clockwise
for more liquid.
3. Repeat steps 1 and 2 until calibration is acceptable.

Operating Instructions

For accurate measurement and to prevent meter damage, meter and piping must always be lled with liquid and
free of air. Meter should be calibrated per instructions in this manual prior to its use.
1. Stop ow of liquid.
2. Reset register to "0".
3. Meter is ready for use. Start ow of liquid. Do not exceed 50 PSI of line pressure.

Maintenance

Your Fill-Rite 900 Series Meter should operate virtually maintenance free. Certain liquids, however, can dry out while in
the meter housing, causing the meter to stop or perform poorly. If this happens, meter should be thoroughly cleaned.

Cleaning Instructions

Run a ushing uid through the meter. For a more thorough cleaning, disassemble the meter per "ASSEMBLY /
DISASSEMBLY" section, "Meter Chamber Assembly" subsection. Rinse all meter components thoroughly.
Recalibrate meter following calibration instructions above.
NOTICE
When a meter is sent in for maintenance, it should be triple rinsed and accompanied
by a note indicating what chemicals have been pumped through it. Meters that do not
adhere to these specications may be rejected.

Storage

If your meter is to be stored for a period of time, clean it thoroughly. This will help protect the meter from possible damage.
