Description

The compact Gilflo ILVA flowmeter is a three element flowmeter.

It operates on the spring loaded variable area principle and

produces a differential pressure related to the flowrate. The ILVA

pipeline element is connected to the Scanner 2000 steam mass

flow transmitter via a compact stem and isolation manifold.

The compact ILVA flowmeter is supplied as separate elements

(calibrated) as standard, although the pipeline element (ILVA) and

Scanner 2000 are a matched pair.

The flowmeter can also be supplied as a fully assembled and

calibrated system on request.

Sizes and pipe connections

DN250 and DN300.

Suitable for fitting between the following flanges:

EN 1092 PN16, PN25 and PN40.

ASME B 16.5 Class 150, 300 and 600.

JIS 20 / KS 20.

The Gilflo ILVA flowmeter should be installed in pipework

manufactured to BS 1600 or ASME B 36.10 Schedule 40.

For different pipe standards/schedules, downstream spool

pieces with an equivalent internal diameter to BS 1600 or

ASME B 36.10 Schedule 40 should be used. If this is not

possible, please contact Spirax-Sarco Limited.

Configuration

The Gilflo ILVA and Scanner 2000 are uniquely configured at the

factory as a matched pair for a specific application. For correct

operation they must be installed together. A label on the packaging

gives the serial number of the matched products.

The product can be configured using an RS485 equipped PC with

the supplied configuration software.
