ILVA Flowmeter
Description The ILVA flowmeter operates on the spring loaded variable area principle and produces a differential pressure related to the rate of flow. It can be used with most industrial fluids, gases and both saturated and superheated steam. A general description of the ILVA flowmetering system and its associated equipment is given in a separate TI sheet. Sizes and pipe connections DN50, DN80, DN100, DN150, DN200 (2", 3" 4", 6", 8"). For DN250 and DN300 (10" and 12") sizes see separate literature. Suitable for fitting between the following flanges: EN 1092 PN16, PN25 and PN40. BS 10 Table H. ASME B 16.5 Class 150, 300 and 600. JIS 20. KS 20. The 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 equivalent internal diameter as in BS 1600 or ASME B 36.10 Schedule 40 should be used.
