It is a sensor to continuously measure a hydrostatic pressure of a
liquid according to the certain height of the liquid column.
Hydrostatic pressure is calculated using the equation given below.
P = ρ x g x h
[P=Hydrostatic Pressure, ρ =Density of Liquid,
g=Gravity of Acceleration, h=Height of Liquid Column]
As seen in above equation, if density of liquid does not change, measured hydrostatic pressure is
detected as an electric signal proportional to the height of liquid column, since the height of
liquid column is only
variable
.
Installation on top or side of tank.
Easy installation and maintenance
No effect by a conductivity or composition change of medium
It is required attention because it is affected by a change of density.
HT-100P Series is a Hydrostatic Pressure Type Level Transmitter installing in top or side of tank
continuously measures the liquid levels in the tank. It measures hydrostatic pressure and converts
it to the current output, DC 4~20mA. It can be widely used in various industries such as PC Tank,
Dam Surge Tank, Sluiceway. River and Wastewater special work.
