The Gilflo ILVA is used in conjunction with linearising electronics such as a Spirax Sarco flow computer or M750 display unit.

Alternatively the output signal linearisation can be performed on an EMS/BEMS or equivalent.

Accuracy when used with Scanner 2000 or M750:

±1% of measured value from 5% to 100% of maximum rated flow.

±0.1% FSD from 1% to 5% of maximum rated flow.

Repeatability better than 0.25%

Turndown: up to 100:1

Caution: The Scanner 2000 mass flow transmitters can be configured at the factory to work with a single, specific Gilflo ILVA flowmeter.

For correct operation the configured transmitter must always be installed with its allocated flowmeter. Labels on the packaging give the

serial numbers of the matched products.

Pressure drop

The maximum pressure drop across the Gilflo ILVA pipeline unit is 498 m bar (200 ins water gauge) at maximum rated flow.

Flow capacity

To determine the capacity of the Gilflo ILVA for different fluids, it is necessary to calculate the equivalent water flowrate Q

E

(in l/min)

as described in Step 1, under the section 'sizing the Gilflo ILVA' then selecting the appropriate size of flowmeter from the Table under

Step 2 overleaf.
