Level Sensor - Wikipedia
Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as well as bulk solids. They are also widely used in water treatment applications for pump control and open channel flow measurement. The sensors emit high frequency (20 kHz to 200 kHz) acoustic waves that are reflected back to and detected by the emitting transducer. ... Read Article

Capillary Flow Porometry - Wikipedia
Capillary flow porometry, The contact angle θ depends on the interaction between the material and the wetting liquid. Silicone oil does not present the evaporation drawback but its high viscosity makes the cleaning of the equipment parts in between different measurements not easy. ... Read Article

Surface Tension Of Molten Metals Using The Sessile Drop Method
The sessile drop method was selected for this study. It is considered one of the two best methods for obtaining molten metal surface tension data, and UHV equipment was available to prevent surface contamination. The sessile drop method also provides contact angle data which are valuable in measuring wetting. ... Access This Document

Non Contact Measurement Of Surface Roughness By Conoscopic ...
Measurement is particularly important in the precision industry where requirements of surface finishing are more demanding every day. The measurement of roughness can be performed by means of contact or non-contact methods. Contact methods use a touch probe which is slipped on the surface to be measured. ... Retrieve Content
