GENERAL INFORMATION

The Groz M10 In-Line Flow Meter has incorporated the oval rotor principal into its design. This has proven to be a highly reliable and accurate method of measuring flow, providing exceptional repeatability and high accuracy over a wide range of fluid viscositiesand flow rates.The low pressure drop through the meter makes the meter ideally suited for use in gravity and pump (in-line) applications.

Flow meters are available in either Aluminium or316 Stainless Steel. Standard rotors are made fromPPS (Polyphenylene Sulfide Resins).

Mechanical displays have a re-settable batch totaliser and non-re-settable accumulative totaliser.

Please take a few minutes to read through this manual before installing and operating your meter. Always retain this manual for future reference.

This manual contains connection and operating instructions for meters with mechanical displays.

If you experience any problems with the product, refer to the Maintenance and Trouble Shooting sections of this manual.

If

you need assistance, contact the dealer from whom you purchased your meter. If you feel you need further assistance, feel free to write to Groz at info@groz-tools.com

INTRODUCTION

IMPORTANT INFORMATION

PLEASE READ THIS INFORMATIONCAREFULLY BEFORE USE!

Before use, confirm the fluid to be used iscompatible with the meter. Refer to Industryfluid compatibility charts or consult your localrepresentative for advice.

To prevent damage from dirt or foreign matter it is recommended that a Y or basket type 60mesh strainer be installed as close as possible to the inlet side of the meter. Contact your local representative for advice.

Note: When a strainer is installed it should beregularly inspected and cleaned. Failure tokeep the strainer clean will dramatically effectflow meter performance.

Note: To prevent damage caused by air purgeslowly fill the meter with fluid. To reducepressure build up, turn off the pump at the end of each day.

OPERATING PRINCIPLE

When fluid passes through the meter the rotors turn, as shown below. The gear located on top of one of the rotors drives the mechanical registers gear train which then provides an accurate readout.

INSTALLATION

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 interrupting production. (See Fig.1)

1

2. Use thread sealant on all pipe threads.3. For pump applications ensure pipe work has the appropriate working pressure rating to match the pressure output of the pump.4. Install a wire mesh strainer (Y or basket type) as close as possible to the inlet side of the meter.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.6. The meter can be installed in any orientation as long as the meter shafts are in a horizontal plane. (Refer to Fig.2 for correct installation)

Note: Incorrect installation can causepremature 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 decreases.

SERVICE INSTRUCTIONS

Disassembly

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

1. Remove the four screws (Item 17) located on the face of the register. Then remove the face plate cover including register assembly.2. Remove the four register mounting screws (Item 15) and remove the lower half of the register housing.3. Remove the six cover plate screws (Item 12) and remove the cover plate (Item 11).4. Remove the four meter cap screws (Item 5) and remove the meter cap (Item 4).5. Remove rotors (Item 3).

Reassembly

1. Clean all components before reassembly.2. Before reassembling check the condition of the rotors (Item 3). Replace if necessary.3. Replace the rotor (with the gear) on the short shaft in the housing then place the 2nd rotor onto the shaft so as the rotors are at 90° to each other. (Refer Fig.3). Check rotor 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 it correctly at 90° to the other rotor. Recheck the operation of the rotors.4. Inspect the gears (Item 6) in the meter cap (Item 4) for wear. (Replace if required, refer to spare parts on page 5.5. Replace the o’ring (Item 2) 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 meshing correctly with the gear in the meter cap (Item 4). Insert the cap head screws (Item 5) and tighten in a diagonal sequence 1, 4, 2, 5, 3, 6

8. Replacement of output shaft, bush and seal.

Disassembly of output shaft

a. Remove the bevel gear.b. Remove the circlip and push out the outputshaft assembly, including washer.c. Remove the seal.d. Carefully press out the output shaft bush (Ifrequired).

7. Inspect the bevel gear (Item 13), o-ring (Item 10) for wear or damage. (Replace faulty components if necessary).

Assembly of output shaft

a. Carefully press the new output shaft bush into place (Use Loctite Primer 7471, as per instructions, followed by sealant Loctite 680)b. Insert a new seal into the groove of the output shaft bush.c. Replace the output gear and washer and replace the circlip to lock the output gear shaft into place.d. Replace the bevel gear (Item 13) and tighten the grub screw onto flat face of shaft.

9. Place the o-ring (Item 10) into the groove in the meter cap (Item 4). (Replace the o-ring seal if required).10. Place the cover plate onto the meter. Replace the cover plate screws and tighten the six cap head screws (Item 12) firmly.11. Place the lower cover plate of the register into position. Replace the four screws (Item 15) and tighten.12. Position the register correctly on top of the lower register cover. Replace the four screws (Item 17) and tighten.13. Test the meter by turning the rotors with a finger or by applying low air pressure (No more than a good breath) to one end of the meter, before returning meter to the line.

TROUBLE SHOOTING GUIDE

TROUBLE CAUSE REMEDY

Fluid will not flow through the meter

a. Foreign matter blocking rotors

b. Line strainer blockedc. Damaged rotors

d. Meter connections over tightenede. Fluid is too viscous

a. Dismantle meter, clean rotors, (strainer must be fitted in line)b. Clean Strainerc. Replace rotors (strainer must be fitted in line)d. Re-adjust connectionse. See specifications for maximum viscosity

Reduced flowthrough the meter

a. Strainer is partially blockedb. Fluid is too viscous

a. Clean strainerb. See specifications for maximum viscosity

Meter readinginaccurate

a. Fluid flow rate is too high or too lowb. Fluid is too viscousc. Excess wear caused by incorrect installation
