Experiences with a Density Meter

The use of this instrument, utilising galvanic action to indicate the density of massecuite as a guide to crystallization in sugar-boiling vacuum pans and its construction from cheap and readily available materials are enlarged upon. Difficulties experienced in the instrument's successful operation are enumerated and the means of overcoming these are set forth as a guide to present and future o...

Noise and Noise Meter Kay Hammer Noise and Noise Meter

In order to make use of analysis and low noise design techniques one requires a knowledge of the noise performance of circuit elements, circuits and complete systems in order to determine whether they meet the specifications or not. Also to judge the effort of noise decreasing procedures in circuits one need to be able to measure the noise level. If high precision noise measurement is required ...

Analysis of a point-source integrating-cavity absorption meter.

We evaluate the theoretical performance of a point-source integrating-cavity absorption meter (PSICAM) with Monte Carlo simulations and a sensitivity analysis. We quantify the scattering errors, verifying that they are negligible for most ocean optics applications. Although the PSICAM detector response is highly sensitive to the value of the wall reflectivity, the absorption of an unknown fluid...

Piezoceramic Element Design and Fabrication for Ultrasonic Transducer of Gas Meter

Ultrasonic transducers play a significant role in generating and receiving the acoustic waves in ultrasonic flowmeters. Depending on the required accuracy, the ultrasonic transducers can be installed either in one pair or more in an ultrasonic flowmeter. The main part of an ultrasonic transducer is its piezoceramic element. In this work, four piezoceramic elements with different diameter to thi...

Gas-liquid chromatography: the gas-density meter, a new apparatus for the detection of vaporus in flowing gas streams.

The separation of volatile substances by gasliquid chromatography (James & Martin, 1952; James, Martin & Smith, 1952; James, 1952; James & Martin, 1954; Ray, 1954a, b) requires that the substances be detected as they leave the chromatogram in the stream of gas that acts as the mobile phase of the system. A number of methods of detection of varying sensitivity have already been developed (James ...
