Density or Interface*
Calculate the minimum and
maximum pressure differentials to
be measured.
Pmin = (SGmin - SGf) x (d);
minimum density, 4mA
output
Pmax = (SGmax - SGf) x (d);
maximum density, 20mA
output
Where:
d = distance between the
taps
SGmax = maximum Specific
Gravity
SGmin = minimum Specific
Gravity
SGf = Specific Gravity of
capillary fill fluid (see
page 11 for values)
