Determination of the measuring range in case of media with a density 1000 kg/m3 (medium water)

2

+

ρ

Calculation of the measuring range:

p = ρ x g x H

with:

ρ= density of medium

g = local acceleration due to gravity H = maximum level

Example:

Medium: Diesel fuel = 850 kg/m3

Acceleration due to gravity: 9.81 m/s2

Start-of-scale : 0 m

Maximum level: 6,2 m

Calculation:

p= 850 kg/m3 x 9.81 m/s2 x 6.2 m

p= 51698.7 N/m2

p= 517 mbar

Transmitter to be ordered:

7MF1570-5ZA02-Z

J1Y: 0 ... 517 mbar; able length e.g. 8 m
