Abstract

A flexible liquid level sensor board assembly (100) for application with liquid level sending units (250) is presented. The liquid level sending unit (250) includes a stem (210), float (230), and a flexible sensor board assembly (100). The flexible sensor board assembly (100) is a distinct component of the sending unit (250) and as such is capable of repeated insertion and removal from the stem (210). The flexible sensor board assembly (100) is therefore ideal for existing/retrofit applications and new installations alike.
