WATER-LEVEL INDICATOR WITH REMOTE READING INDICATOR AND SITE READING INDICATOR
Document Type and Number:
Japanese Patent JPS57201818
Kind Code:
A
Abstract:
A liquid level (e.g. boiler water level) indicating assembly (10) has an optical system (22) for establishing an optical signal indicative of liquid level, which signal is split by a beam splitter (18) to transmit the majority of the optical signal to a fibre optic cable (16) and to reflect a part of the signal to a proximately located display means (13) in the form of a glass diffuser (14). The cable (16) extends to a matte screen (12) at a remote location to thus provide a remote optical display (11) as well as the local optical display (13) of the liquid level.
