Liquid Nitrogen Level Measurement

The LN2 level in the Dewar is determined through the use of a differential pressure sensor. This
sensor operates on the physical principle of hydrostatic head pressure. The pressure generated
by a column of fluid is proportional to the height, or depth, of the fluid column. In this
application, the pressure generated by the LN2 at the bottom of the freezer will increase as the
LN2 level increases. This differential pressure system allows the controller to measure the
exact LN2 level accurately.

Figure 4:

As the fluid level in the cylinder increases, the imposed head pressure at the bottom of the

cylinder increases proportionally. The pressure gauges measure this increase in level.

This pressure signal generated by the LN2 is transmitted from the bottom of the inner vessel
through the freezer’s annular line to the differential pressure sensor inside the TEC 3000
controller. The TEC 3000 controller then compares this pressure signal to its atmospheric
pressure readings and is then able to determine the exact LN2 level. The term “differential
pressure” refers to the fact that the level is determined from the difference between the
hydrostatic head pressure of the fluid column and atmospheric pressure. The measured LN2
level is displayed in inches, millimeters, or as percentage full.

Unlike alternative level sensing systems, such as thermistor based systems, differential
pressure allows the exact level to be measured and displayed, not just a level range. This
completely enclosed system requires minimal maintenance and is not affected by humidity,
moisture, or other environmental variables. Also, the differential pressure system allows the
automatic level settings and alarms to be set and adjusted electronically instead of having to
physically move sensors.
