INTRODUCTION

Thank you for purchasing a Macnaught AMFM Mechanical

Diesel Meter.

The AMFM meter is a mechanical nutating disc meter providing a reliable, accurate method of measuring diesel. The meter has two totals available (resettable batch total and nonresettable total).

Macnaught manufacture a full range of pumps, meters and accessories to suit most of your fluid transfer needs. Please consult your local Macnaught reseller for more information.

Please read and retain this instruction manual to assist you in the operation and maintenance of this quality product.

GENERAL INFORMATION

This manual assists you in operating and maintaining your new Mechanical Diesel Meter. The information contained will help you ensure many years of dependable performance and trouble free operation.

Your in-line nutating meter is designed to accurately measure low viscosity fluids and water. This nutating disc meter is ideal for use on low pressure in-line applications, mobile installations and electric diesel pumps, generally fitted close to the dispensing nozzle.

OPERATION

Both the batch total and accumulative total will turn simultaneously when fluid passes through the meter.

Turn the reset knob to reset the batch total to zero.

INSTALLATION

The meter has been manufactured for standard horizontal fitting with a flow direction from left to right. The orientation can be changed using the following procedure.

1. Remove the 4 screws that hold meter cover.

2. Remove the 2 screws that hold register.

3. Remove the 8 screws that hold meter aluminium top.

4. Turn the body to the desired location, ensure you do not damage the sealing body o-ring.

5. Tighten the 8 screws that hold meter aluminium top, do not exceeds max torque of 4,5 Nm.

6. Carefully fit the register to the meter body, ensure you do not bend the pinion shaft.

7. Tighten the 2 screws that hold register, do not exceeds max torque of 2 Nm.

8. Carefully place the meter cover.

9. Tighten the 4 screws that hold meter cover, do not exceeds max torque of 2 Nm.

CAUTION

Observe precautions against fire or explosion when dispensing flammable liquid. Do not operate the meter in the presence of any source of ignition including running or hot engines, lighted cigarettes or gas or electric heaters.

Ensure that you follow all the correct earthing and grounding procedures before use.

Inspect seals and connections for leaks weekly when using flammable liquids.

Do not use Teflon tape on any connections when using flammable liquid.

Do not use this meter with gasoline or any fluid other than the compatible fluid specified in this manual.

Do not use the meter above the maximum pressure of 3.5

bar.

NOTE: When fitting meter, ensure direction of flow is the same as the arrow cast to underside of the meter.

Macnaught recommends that a filter screen of at least 40 mesh is installed prior to the flow meter. Macnaught has a

HA1S (10 micron) fuel filter available if required.

DO NOT exceed a maximum pressure of 3.5 bar (50psi).
