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 build
assembles (base and metering module) of 20 modules or more.
OPERATING PRINCIPLE
Liquid flowing through the meter module moves a "satellite" within a fixed rotation. Every rotation is monitored by an optical
sensor that transmits the signal to a control device. The operator may read the liquid delivered in litres per minute or the
revolutions number per minute directly from the FACT device-display or from a PC monitoring software.
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 IDENTIFICATION
Machine identification red label is located on the front side of the unit and contains machine serial number.
