  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Measurement matters

    The following article highlights some of the latest developments within the Energy Institute’s Hydrocarbon Management Committee (HMC), which produces guidance documents covering petroleum quantity and quality issues.

  • Conductivity Theory and Measurement

    Electrical conductivity is a measure of the ability of a solution to cany* a current. Current flow in liquids differs from mat in metal conductors in that electrons cannot flow freely, but must be carried by ions. Ions are formed when a solid such as salt is dissolved in a liquid to form electrical components having opposite electrical charges. For example, sodium chloride separates to form Na" ...

  • Contact-free indirect measurement

    The non-contact mode of measurement is very interesting for hygienic applications in the food-, pharmaceutical- and cosmetics industry, as well as for industrial applications with thick, adhesive and solid containing liquids. Experience has shown that conventional volumetric flow meters quickly come to their limit, while other measuring procedures are often very complex and/or are not suitable ...

  • Radiation Monitors and Meters

    Light Description and Applications The light meter is a portable unit designed to measure visible, UV, and near-UV light in the workplace. (The CTC has a UV light meter available through its loan program, ALEP.) The light meter is capable of reading any optical unit of energy or power level if the appropriate detector has been calibrated with the meter. The spectral range of the instrument is ...

  • Industrial thermal mass flow meters Pt.1 -Pt.2 - measurement & control

    An industrial thermal mass flowmeter measures either the mass velocity at a point in a flowing gas or the total mass flow rate through a channel or pipe. Figure 1 shows a typical thermal mass flow sensing element. It consists of two sensors: a mass flow sensor and a temperature sensor, which automatically corrects for changes in gas temperature. Both sensors are reference- grade platinum ...

  • Speech Intelligibility Measurements in an Office Building

    This study investigates how changes to an emergency voice communication system (EVCS) or the building environment affect speech intelligibility in four spaces of an office building: lobby, stairwell, dining area, and open-floor-plan office space. Effects of additional or alternate speaker locations, floor and wall coverings, and background noise on intelligibility are measured via objective means ...

  • What is 61-channel resistivity meter?

    FlashRES resistivity meter has 64 electrodes, it uses one common ground electrode, two electrodes as current injection electrodes. For each current injection between A and B, the FlashRES resistivity meter measures the potential on remaining electrodes against the common ground electrode. In this way, 61 MN voltages are measured and hence FlashRES is a 61 channal resistivity meter. ...

  • The Fatal Flaw in Dew Point Measurement for Injection Molding

    Dew-point measurement is a common and important metric in the plastic drying process. A good dew point meter can tell you whether your dryer is working normally or if it’s in need of repair. Dew point meters do this by measuring the humidity in the air that flows through the dryer. What dew point meters won’t tell you anything about, however, is how much moisture is actually present ...
