when dispensing flammable fluids. Fire could result.

Do not exceed 50 PSI / 3.5 BARS line pressure.

CAUTION: Do not install additional foot valve or check valve
during installation without pressure relief valve. Cracking
may result.

SERIES 800C

METER

Models 806C, 807C

Meters are furnished for horizontal piping, left to right flow,

unless otherwise specified. Use oil and gasoline resistant

pipe compound on all threaded joints. Flow ports can be

located in any of four positions for horizontal or vertical piping.

1. If fluid flow is left to right, install meter.

2. If fluid flow is other than left to right, determine direction of fluid

flow.

3. Lay meter dial face down on a clean flat surface.

4. Arrow mark on meter housing indicates fluid flow direction.

5. Remove four screws (item 20).

6. Lift meter housing (item 19) and chamber assembly (item

26) and rotate together to desired flow direction.

CAUTION: Chamber opening must face towards inlet port of

meter.

7. Replace four screws (item 20).

8. Install meter.

The Fill-Rite Series 800C meters can be calibrated for either U.S.

gallons or liters. Calibration is required after disassembly, when

metering a different fluid, or after significant wear. Depending on

the model, Series 800C meters are factory calibrated in either

U.S. gallons or liters using mineral spirits.

Meter calibration can be easily changed by using the calibration

procedure noted. A container of KNOWN volume will be needed

for the calibration procedure. It is recommended that the

container’s volume be at least five gallons or larger.

For accurate measurement, meter and piping must always be

filled with liquid and free of air. Meter should be calibrated per

instructions in this manual prior to its use.

1. Stop flow of liquid.

2. Reset meter to “0”.

3. Meter is ready for use. Start flow of liquid. Do not exceed

50 PSI line pressure.

OPERATING INSTRUCTIONS

MAINTENANCE

Meter should operate maintenance free. However, certain

liquids can dry out while in the meter housing, causing the

meter to stop. If this happens, meter should be thoroughly

cleaned (see instructions below).

Cleaning Instructions:

Run a flushing fluid through meter. For a more thorough

cleaning, disassemble meter per “ASSEMBLY /

DISASSEMBLY” section, “Meter Chamber Assembly”

subsection. Rinse all meter components. Recalibrate meter

following calibration instructions above.

Storage:

If meter is to be stored for a period of time, clean thoroughly. This

will help protect meter from damage.

TROUBLESHOOTING GUIDE

Counter is reading high or low:

Check calibration and recalibrate if necessary. Check for air

in product and repair air leaks. Measuring chamber or gears

could be sticking. Correct by cleaning or replacing internal

metering components.

Shaft seal leakage:

Possible causes are dirty or damaged seals. Correct by

cleaning o-ring and seat area or replacing seal.

Gasket leakage:

Correct loose gasket by tightening joints. Clean dirty gaskets

and seat area. Replace damaged gaskets.

Low flow capacity:

Clean clogged meter chamber; clean or replace screens and

filters in piping.

Meter body cracks:

Install pressure relief valve to allow high pressure to bleed back

to tank.

Nutating disc breaks:

Avoid flow surge by putting shut-off valve on outlet of meter;

place meter as close as possible to pump; keep piping full of

liquid.

Procedure for Calibration

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 indicated amount does not match known volume, insure

pump is off and pressure relieved, then remove seal screw

(item 23) and turn calibration screw (item 21)

counterclockwise to reduce indicated amount or clockwise

to increase the amount. A full turn will change the indicated

amount by approximately 0.1 Gal. (0.4L).

Reinstall seal screw.

3. Repeat step 1 and 2 until calibration is acceptable.
