3.2 Description
The device measures the filling level of a liquid medium. It
transmits the measured value via a current output.
To calculate the filling height, use the following formula:
p(h) = ρ*g*h
Formu-
laic
symbol
Meaning
p(h) Hydrostatic pressure as a function of the liquid
column
ρDensity (for example of water: 998.2 kg/m³ at
20 °C); [ρ]=kg/m³
gLocation factor (gravitational acceleration,
gnorm = 9.80665 m/s²); [g] = m/s²
hHeight of liquid column; [h] = m
