To the Owner

PLEASE READ THIS SAFTEY INFORMATION CAREFULLY BEFORE USE.

Read and retain this instruction manual to assist you in the operation and maintenance of this product.

This Flow Meter has incorporated the oval rotor principal into its design. This has proven to be a reliable and highly accurate method of measuring flow.

Exceptional repeatability and high accuracy over a wide range of fluid viscosities and flow rates are features of the oval rotor design. With a low pressure drop and high pressure rating oval rotor flow meters are suitable for both gravity and pump (in line) applications.

If you have any problems with the meter, refer to the maintenance and trouble shooting sections of this manual.

This manual contains connection and operating instructions for meters with Mechanical Displays

If you need further assistance, contact your local representative or distributor for advice.

IMPORTANT INFORMATION

FLUID COMPATABILITY

Before use, confirm the fluid to be

used is compatible with the meter. Refer to Industry fluid compatibility charts or consult your local representative for advice.

STRAINER

To prevent damage from dirt or foreign matter it is recommended that a Y or Basket type mesh strainer be installed as close as possible to the inlet side of the meter. When a strainer is installed it should be regularly inspected and cleaned. Failure to keep the strainer clean will dramatically effect flow meter performance. Contact your local representative for advice.

AIR PURGE / LINE PRESSURE

To prevent damage caused by air purge slowly fill the meter with fluid. To reduce pressure build-up turn off the at the end of each day.

4

OPERATING PRINCIPLE

When fluid passes through the meter the rotors turn, as shown in the diagram below. One of the rotors is fitted with a gearing pinion which (through a secondary gearing set) transfers the rotation of the rotor to the Mechanical Register.

INSTALLATION PROCEDURE

6. The meter can be installed in any orientation as long as the meter shafts are in a horizontal plane. (Refer to diagram below for correct installation)

The mechanical register can be removed and re orientated to a different plane if required.

.

1. It is recommended that when setting up pipe work for meter installations, a bypass line be included in the design. This provides the facility for a meter to be removed for maintenance without interrupt ing production. (see figure above)

2. Use thread sealant on all pipe threads.

3. For pump applications ensure pipe work and

Meter have the appropriate working pressure rating to match the pressure output of the pump. Refer to Meter Specifications section for further details. direction.

4 Install a wire mesh strainer, as close as possible

to the inlet side of the meter.

Meter 1/2”- 2” 250 micron / 60 mesh

5 Ensure that the meter is installed so that the

flow of the liquid is in the direction of the arrows embossed on the meter body.

Note: Incorrect installation can cause premature wear of meter components.

7. Do not over tighten meter connections. .

8. It is important that after initial installation you fill the line slowly, high speed air purge could cause damage to the rotors.

9. Test the system for leaks.

10. Check the strainer for swarf or foreign material,

after the first 200 litres check periodically, particularly if the flow rate is noted to be decreasing.

Maintenance Procedures

Disassembly - Flow Meter

Ensure that the fluid supply to the meter is disconnected, and the line pressure is released before disassembly. Refer to the exploded parts diagram and parts list.

1) Remove the four screws located on the face of the register. Then remove the face plate cover including register assembly.

2) Remove the four register mounting screws and

remove the lower half of the register housing.

3) Remove the six cover plate screws and remove

the cover plate.

4) Remove the six meter cap screws and remove the

meter cap.

5) Remove rotors.

Reassembly - Flow Meter

1) Before reassembling check the condition of

the rotors (replace if necessary).

Note: there is one long and one short shaft. The short shaft is to accommodate the rotor with the gearing pinion fitted

2) Replace the rotors onto the shafts at 90 degrees

to each other and check their operation by turning either of the rotors. If the rotors are not in mesh correctly or do not move freely, remove one of the rotors and replace correctly at 90 degrees to the other rotor.

3) Re-check the operation of the rotors

4) Inspect the gears in the meter cap for wear.

(Replace if required, refer to exploded diagram)

5) Replace the o’ring into groove in the meter cap, if

the o’ring has grown or is damaged in any way

replace it with a new part.

6) Replace the meter cap making sure that the gear

on the rotor is meshing correctly with the gear in the meter cap. Insert the cap head screws and tighten in a diagonal sequence 1, 4, 2, 5, 3, 6.

7) Replace the cover plate inspect the o-ring, bevel

gear, for wear or damage. (Replace if necessary).
