Types of Level Measurement Transmitters & How Do They Work?

4/20/2018 · As the name suggests, a level measurement transmitter is an instrument providing continuous level measurement. It can be used to determine the level of liquid or bulk-solid at a particular time. Levels of media such as water, viscous fluids, and fuels, or dry media such as bulk solids and powders can be measured using the transmitter.

Sound Level Meter / Noise Level Meter | PCE Instruments

The Sound Level Meter / Noise Level Meter PCE-MSL 1 is a simple sound measuring device. The PCE-MSL 1 sound level meter / noise level meter is used to quickly determine the ambient noise level. In addition to the volume measurement, the PCE-MSL 1 sound level meter / noise level meter also has the option of determining the ambient temperature.

High Process Noise - Emerson Electric

the high process noise diagnostic, the transmitter specifically looks at the signal amplitude at frequencies of 2.5 Hz, 7.5 Hz, 32.5 Hz, and 42.5 Hz. The transmitter uses the values from 2.5 and 7.5 Hz and calculates an average noise level. This average is compared to the amplitude of the signal at 5 Hz.

Audio noise measurement - Wikipedia

Audio noise measurement is carried out to assess the quality of audio equipment, such as is used in recording studios, broadcast engineering, and in-home high fidelity.. In general, noise refers to unwanted sound, but in audio systems it is the low-level hiss or buzz that intrudes on quiet passages that is of most interest.All recordings will contain some background noise that was picked up by ...
