Functional description

The VA Master FGM1190 series flowmeters work according to

the float principle.

The position of the float in the conical glass meter tube is

proportional to the flow. It can be read on the scale fitted to

the meter tube.

Four different types of scale can be used:

• Directly readable scale in flow units

• Percentage scale

• DK/DS scale

• Millimeter scale

When using the DK/DS scale a flow rate table is available for

the flowmeter. For other operating conditions, the user can

create additional tables.

Flowmeters in sizes ½ in to 2 in are provided with a

percentage scale in the standard design. The device has a

factory plate indicating the flow rate for the display of 100 %.

The other scale values can be linearly converted. A special

reading curve is therefore not required.

On request, conversion equations for flow calculation for

other operating conditions will be made available.
