A liquid densitometer is constructed using loudspeaker technology. It carries a fluid sample chamber. The increased mass loading causes a shift in resonant frequency of the loudspeaker when driven in positive feedback. With suitable calibration the shift in frequency provides a measure of the density of the fluid sample. In a modification, two loudspeakers are mounted back to back with the opposing diaphragms defining a sample chamber.

Gasoline analyzer is an on-line process analyzer for accurate multi-component gasoline analysis. Utilizing mid-infrared spectroscopic analysis to differentiate and quantify individual components in a gasoline sample, this analyzer is ready to measure right out of the crate. It minimizes need for the special calibrations and correlations common in competitive technologies and instrumentation.

Gauge Cock is a stopcock used as a try cock for ascertaining the height of the water level in a steam boiler. Gauge cock is provided immediately upstream from the final rinse sprays to permit checking the flow pressure of the final rinse water. It is used in a variety of industrial and application-specific pressure monitoring applications.

Level Gauge Glass is made from borosilicate. It is used in lever gauge in boiler for water position.

Gauge snubber is an adjustable restriction type instrument. It helps protect instrument against pulsing and surges in process system. It also suitable for use with pressure gauges, pressure switches and pressure transmitters.

Gear Flowmeters are used to get accurate flow measurements with viscous fluids. These flowmeters work by forcing specific volumes of fluid between two coupled gears.

The gear-tooth sensors are smart sensors that learn about their targets to optimize the magnetic circuit detection. It contains a samarium-cobalt magnet, a pole piece, and a differential hall effect IC that has learning capability. These sensors can be easily used in conjunction with a wide variety of gear or target shapes and sizes. It is a solid-state speed sensor can detect the motion of various ferrous objects with some type of discontinuous surface.

General Purpose Reflective Sensors includes inexpensive general purpose diffuse-reflective, retro-reflective and polarized retro-reflective sensors. General purpose reflective sensors are useful for simple applications where a basic sensor provides adequate sensing performance.

General-purpose rotating machinery diagnostic systems are used in personal computers to analyze, diagnose, and manage all data required by general purpose rotating machines.

Glass electrode is potentiometric sensor made from glass of a specific composition. It is a hydrogen-ion responsive electrode usually consisting of a bulb, or other suitable form, of special glass attached to a stem of high resistance glass complete with internal reference electrode and internal filling solution system. The glass electrode, which consists of a thin wall glass bulb, has an extremely high electrical resistance.

Glass thermometers are accurate, economical instruments that measure temperatures of liquid or gas. The accuracy of a glass thermometer is approximately ±1 scale division.

Glass tube rotameter is an industrial flowmeter used to measure the flow rate of liquids and gases. The rotameter consists of a tube and float. The tube is precision formed of borosilicate glass, and the float is precisely machined from metal, glass or plastic. The metal float is usually made of stainless steel to provide corrosion resistance. The float has a sharp metering edge where the reading is observed by means of a scale mounted alongside the tube.

Gloss Meter ensures high accuracy measurements. It evaluates the glossy surfaces of coatings, plastics, ferrous and nonferrous metals, and paper for quality control application. Dual-purpose model measures both gloss and coating thickness at the same spot. It displays single measurements or statistics including the number of readings, mean, and standard deviation. It features a scroll wheel and single button for easy operation. Meters also feature additional statistical functions including minimum and maximum readings, range, difference and pass/fail.

Glycerine Filled Pressure Gauges are used to resist vibration & pulsation. These gauges are suited to a broad range of plant, process, hydraulic and fluid power applications. Glycerine-filled pressure gauges are suitable for use with pumps, compressors and other mechanical peripherals. The glycerine filled pressure gauges are used in industries such as power plants, marine, pumps, generators and pulp & paper.
