1. INTRODUCTION

This manual refers to FLOW MASTER volumetric flow device.

You can find additional copies and newer revisions of this document from our website http://www.dropsa.com. Alternatively

contact one of our Sales Offices.

This User and Maintenance Manual contains important information on health and safety issues for the personnel.

It is recommended to attentively read this manual and carefully keep it in good condition so that it is always available to

personnel requiring to consult it.

2. GENERAL DESCRIPTION

FLOW MASTER is a volumetric flow meter, which constantly monitors lubrication.

Flow meter precise monitoring, without calibrations or adjustments, is due to volumetric measurements not dependent on

lubricant temperature or viscosity.

FLOWMASTER is a modular system consisting of two elements:

Base

Metering module

MODULAR SYSTEM

The base is common to all size modules, which are also interchangeable. The modular construction makes it possible to built

assys (base and metering module) of 20 modules or more.

OPERATING PRINCIPLE

A “satellite”, which rotates with a fixed orbital movement, is operated by the liquid passage through the metering module. An

inductive sensor picks up each orbital movement and transmits a signal to an electronic reader. The operator can read the

output of the metering module in litres/min or in rev/min directly from the FACT 2000 device-display or from a PC monitor.

VISUAL INDICATION OF THE FLOW OF LIQUID

A “satellite”, built in the module body, rotating with an orbital movement indicates the fluid velocity. The flow output is neither

reduced nor interrupted even if the “satellite” stops.

3. PRODUCT - MACHINE IDENTIFICATION

Machine identification red label is located on the front side of the unit and contains machine serial number.

6. UNPACKING AND INSTALLING THE MACHINE

6.1 UNPACKING

Once a suitable location has been found to install the unit remove the machine from the packaging. Check the device has not

been damaged during transportation or storage. No particular disposal procedures are necessary, as packaging materials are not

dangerous or polluting.

6.2 INSTALLING

Install the flow meter on a proper support surface, free from impediments which could interfere with machine well functioning.

WARNING: All the electric, electronic components, reservoirs and base structure must be grounded.

The stainless steel option makes the FLOW MASTER suitable for applications in harsh, damp or corrosive environments.

- Connect inlet (par. 11.3, fig.1, pos. J) and outlet (par. 11.3, fig.1, pos. K) piping.

- Connect the inductive sensor cables (and the motor cables, for the motorized option) to the electronic control and

monitoring equipment terminal strip (see FACT 2000 User and Maintenance Manual).

To assemble flow meters in batteries, follow the instructions below:

1) Unscrew the two grub screws (par. 11.3, fig.1, pos.1) of the next flow meter.

2) Tighten the two screws (par. 11.3, fig.1, pos.2) to the previous flow meter. Pay attention to the O-Ring correct position

to prevent damages during assembling.

3) Screw again the grub screws (par. 11.3, fig.1, pos.1) to the previous flow meter.

The above operations must be carried out for all the flow meters being assembled.

6.3 TECHNICAL INDICATIONS

It is recommended to use:

- Structural steel piping of proper dimensions

- Grip-ring pipe fittings (To assembly: block pipe fittings and tighten pipes using a vice)

If the machine is operated for the first time:

1. Decrease oil pumping unit pressure and ensure that all the connections are correct and there are no leaks.

2. Increase pressure progressively to suit individual flow requirements.

7. PUMP OPERATIONS

MANUAL OPTION

Output adjusting of the manual FLOWMASTER is easy: through the use of two needle valves the output adjustment can be

coarsely (par. 11.3, fig.1, pos. X) or finely adjusted (par. 11.3, fig.1, pos. Y).

To coarsely adjust:

1. Unlock the locknut of the needle valve.

2. Close the fine adjustment valve (par. 11.3, fig.1, pos. Y), by turning clockwise with a M3 allen spanner.

3. Increase or decrease the output by turning counterclockwise or clockwise, with a M5 allen spanner, the coarse

adjustment valve (par. 11.3, fig.1, pos. X).

It is advisable to make the fine adjustment only after the coarse adjustment, as follows:

- Increase or decrease the output by turning counterclockwise or clockwise, with a M3 allen spanner, the fine adjustment

valve (par. 11.3, fig.1, pos. Y) to suit individual flow requirements.

The fine adjustment valve (par. 11.3, fig.1, pos. Y) only is used for the size “A” module.

7.1 MOTORIZED OPTION

To adjust motorized FLOWMASTER output:

- Close the fine adjustment valve (par. 11.3, fig.1, pos. Y) and let the electronic control equipment start automatically in line

with the setting data.
