The smart level probe APR-2000/Y are used to measure the level in closed tanks where the medium is accessed from the tank top.

Measurement is carried out using an APRE-2000 differential pressure transmitter, enabling compensation for static pressure in the tank. The value processed is just the hydro-static pressure of the medium measured at the level of the diaphragm of the lower seal. This pressure is the sum of the hydro-static pressures of the liquid and vapor phases of the medium. In most practical measurement situations the density of the vapor phase is negligibly small, and therefore the measured hydro-static pressure relates only to the height of the liquid phase column and can be taken as representing the level of the surface of the liquid phase. For media where the density of the vapor phase is significant (e.g. propane) the level found by the method described can be treated as the theoretical level of the liquid level obtained by adding the actual liquid phase to the condensed vapor phase.

Smart Level Probe For Pressure Tanks APR-2000/Y are used to measure liquid levels in closed tanks, with static pressure up to 25 MPa, or 32 MPa for special versions and to measure differential pressure across constrictions such as filters and orifices.

Smart Level Probe For Pressure Tanks APR-2000/Y may be fitted with a range of types of process connectors, which enables them to be used in a variety of conditions such as thick or highly reactive media, high and low temperatures, etc.

Smart Level Probe For Pressure Tanks APR-2000/Y generate a 4…20mA output signal and a digital communication signal in a two wire system (current loop). The use of smart electronics enables regulation of the zero point, the measurement range, damping, radical conversion characteristic and other functions using an Aplisens KAP communicator or from a PC using a Hart/RS232 converter and Aplisens “Raport” configuration software.
