摘要： An optical switch having a housing, and two optical fibers, that can be connected to a light source and a light detector. The optical switch includes a moveable member that moves from a first position to a second position. In the first position, an optical path is present through the two fibers guide using a reflection or emission of light from the glowable member. In the second position, there is no optical path present through the switch.

摘要： A tank gauging system includes an improved level sensor float providing positional information to a level encoder unit having two slotted disks coupled to a gaugehead which alternately admit and interrupt light to optical sensors to provide relative incremental positional change and direction information as well as an error detection capability. The light optical sensors provide two signals, which are directly compared to provide a clock signal for an up/down counter. One of the two signals is delayed and this delayed signal is directly compared against the other signal to provide a direction signal for an up/down counter. A microprocessor converts this information to absolute data and provides it to a transmitter unit. The transmitter may also be provided with data from other gauging sensors, such as an error-compensated temperature measurement of the tank contents. The transmitter may be connected to a remote data acquisition device through isolated inputs and outputs for protection against lightning strikes.

摘要： A total precipitation gauge (10) incorporates a float gauge (16) extending downward to a liquid level (18) in a precipitation storage container. The float gauge (16) is formed with an elongate stillwell (20) extending into the liquid level (18), a float element (22) suspended in the stillwell (20) for rising and falling motion within the stillwell in response to the liquid level, and an elongate code bearing surface (24) coupled to the float (22). A code sensor (34) senses motion of the code bearing surface (34) for generating electrical signals (35) corresponding to motion of the float element and liquid level. The code bearing surface is a flexible coded strip (24) secured at one end to the float element (22) and at the other end to a spring loaded reel (25). The spring force of the spring loaded reel (25) is less than the weight of the float element (22) and ballast (26). The code sensor (34) is an optical interruption sensor with first and second optical sensors (a1,a2) coupled in a quadrature relationship with respect to the coded strip (24) to determine direction of motion of the coded strip (24). The total precipitation gauge may be constructed in the configuration of a removable and replaceable cover (12) for fitting over a precipitation storage container (14). The cover (12) includes a collector passageway (15) for proportionately restricting precipitation passing into the precipitation storage container (14).

摘要： An optical fiber rotary measurement sensor for flow meters and other mechanical devices incorporates a housing having an encoder disc mounted by a drive shaft for driven rotation, the drive shaft being driven by a flow meter mechanism or by any other mechanical device. The encoder forms evenly spaced light absorbing and light reflecting areas at the outer periphery thereof and optical fibers are positioned to project light onto and receive reflected light from the outer periphery of the encoder disc. An opto-electronic signal processor receives reflected light pulses from the reflective surface areas and translates the light pulses into electrical pulses. The electrical pulses are in turn input to electronic display circuitry for providing a digital, analog or other suitable display representative of the rotation of the encoder disc and thus representative of rotary output movement of the flow meter or other mechanical device.
