A liquid level transducer () for mounting to a cryogenic tank includes a mounting head assembly () for connection to the tank () and an elongate sensing probe assembly () extending from the mounting head assembly () and into the tank. The mounting head assembly () has a lower mounting member () connected to the sensing probe assembly (). The mounting head assembly also includes a tank mounting member () with a central bore () and a transverse wall () located within the bore. An upper connecting section () of the member () is threaded into the bore (). A seal () is positioned between the transverse wall () and the upper connecting section (). The upper connecting section () has a corrugated feature that receives and deforms the seal to interlock the components together and increase the sealing surface area therebetween.

Sealed head construction for liquid level transducers

A liquid level gauge for determining the level or volume of liquid within a tank includes a mounting head adapted for connection to the tank, a gauge assembly connected to one side of the mounting head, and an elongate sensing probe assembly extending into the tank. The gauge assembly includes a rotatable gauge plate with a scale located thereon and a rotatable indicator that moves across the scale in response to a change in liquid level. The gauge plate is weighted for rotation toward a gravitational force vector for orientation with an upper surface of the liquid in the tank independent of tank tilt. The sensing probe includes a float rod with an integral coil spring hinge to facilitate installation of the gauge within the tank. A counterweight is adjustable along the float rod to fine-tune float weight or buoyancy for a particular gauge configuration and liquid type.
