Gilflo ILVA Flowmeters System Overview
Flowmeter with variable aperture and reset spring that produces a pressure difference directly proportional to the flow.
Used for most industrial liquids and gases, as well as saturated and superheated steam.
For a general description of a flow meter station with ILV:
see the datasheet.
Dimensions and Connections
DN250 and DN300.
For DN50, DN80, DN100, DN150, and DN200, see the datasheet.
Suitable for mounting between flanges:
- EN 1092 PN16, PN25, and PN40
- ASME B 16.5 Class 150, 300, and 600
- JIS 20
- K20
The Gilflo ILVA should be installed in BS1600 or ASME B36.10 Schedule 40 pipelines. If the Gilflo ILVA is installed in pipelines according to different standards and if the Gilflo ILVA needs to achieve its maximum flow rate, an intermediate piece according to BS1600 or ASME B36.10 Schedule 40, downstream of the transducer, is required.
Pressure and temperature limits:

Characteristics:
The Gilflo ILVA is designed to work in conjunction with electronics for linearization, such as the microprocessor or the electronic display type M750. The linearization of the output signal can also be done by the user's energy management system.
Accuracy when used with the microprocessor or M750 +/- 1% of the measured value at flow rates from 5 to 100% of the maximum flow rate. +/- 0.1% of the scale at flow rates from 1 to 5% of the maximum flow rate. Repeatability is better than 0.25%. The measuring range is up to 100:1.
Note:
The flow transmitter Scanner 2000 is configured with a specific transducer. The Scanner 2000 must always be installed with the corresponding Gilflo ILVA the serial number of the corresponding device is indicated on the label.
Pressure Drop
The maximum pressure drop across the GILFLO-ILVA transducer is 498 mbar at maximum flow rate.
Flow Rates:
To determine the capacity of the Gilflo ILVA for different media, the equivalent water capacity QE (in l/min) must be calculated.
