2. Level sensor - Wikipedia

   en.wikipedia.org/wiki/Level_sensor

   Hydrostatic pressure level sensors are submersible or externally mounted pressure sensors suitable for measuring the level of corrosive liquids in deep tanks or water in reservoirs. Typically, fluid level is determined by the pressure at the bottom of the fluid containment (tank or reservoir); the pressure at the bottom, adjusted for the ...

3. Water metering - Wikipedia

   en.wikipedia.org/wiki/Water_metering

   Ultrasonic water meters use one or more ultrasonic transducer to send ultrasonic sound waves through the fluid to determine the velocity of the water. Since the cross-sectional area of the meter body is a fixed and known value, when the velocity of water is detected, the volume of water passing through the meter can be calculated with very high ...

4. Ultrasonic flow meter - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_flow_meter

   Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...

5. Ultrasonic transducer - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_transducer

   An ultrasonic transducer is affixed to a stainless steel pan which is filled with a solvent (frequently water or isopropanol). An electrical square wave feeds the transducer, creating sound in the solvent strong enough to cause cavitation. Ultrasonic technology has been used for multiple cleaning purposes.

6. Custody transfer - Wikipedia

   Current volume of a product stored in a tank can be calculated using a tank capacity table (sometimes called "tank calibration table") and current levels and temperatures of a product in a tank. Tank capacity table stores data about level and appropriate volume in a tank and have a very high impact on overall accuracy of volume calculation.
