Summary FOXBORO 244LD Buoyancy Level Transmitter
The Foxboro 244LD buoyancy level transmitter . In measuring range, the voltage is proportional to the buoyancy, and as the input signal is transmitted to the electronic amplifier. Through the electronic amplifier, voltage is converted to 4-20 mA two-wires output signal. In the two-wires system mode, amplifier is powered by the signal current circuit.
Any part of the displacer immersed in liquid is adhering to the principle of Archimedes. By measuring buoyancy change of cylindrical displacer suspended in liquid, you can measure the liquid level, interface level or density.
When measuring the density and interface level, the displacer should be completely immersed in liquid. The change of the liquid level must be in range area.
The calculation of buoyancy:
FA= VX·ρ1·g+( V -VX) ·ρ2·g
In the formula：FA：Buoyancy
V：The volume of the displacer
VX：In the liquid density of ρ1, the medium volume displacer swaps out
ρ1：The average of the heavy medium density
ρ2：The average of the lighter medium density
g：The local acceleration of gravity
FG： Buoy its own gravity
