Density Effect (Specific Gravity)

Any fluid density change from stated standards has a proportional effect on meter accuracy . Special scales can be supplied if 

actual specific gravity decreases accuracy beyond application limits . Corrections for more or less dense fluids can be made to 

standard scales using the following correction factors:

1 0

.

Specific Gravity

for water/water-based meters

0 876

Specific Gravity

for petroleum-based meters
