The pressure in the liquid phase was measured with a precision transducer, and surface tensions at minimum and maximum bubble radius (minimum and maximum surface tensions) were calculated as a function of time of pulsation from the measured pressure drop across the air-water interface using the Laplace equation for a sphere [67], [68].
In this paper we examine the unique constraint of site attenuation and identify the key factors governing assignment schemes, with particular reference to interference, precision of transducers and noise profiles.
The absolute pressure of the wetting phase at the inlet was measured continuously with the aid of high-precision pressure transducers.
Pressure readings across the core sample were instantly recorded by high-precision pressure transducers that were digitally synchronized to a laboratory PC.
The catheter was then connected to the Honeywell precision pressure transducer PPT-00011 DWWW2VA-B, Honeywell International Ltd, NJ, USA) using a laptop computer interface (Figs 1 and 2).
Inlet, outlet pressures and pressure drop across the core are measured by high precision line and differential transducers.
Thus, quantum squeezing becomes necessary to improve the ultimate precision of graphene-based transducers with ultra-high sensitivity.
We have implemented a precision linear-voltage displacement transducer and added an option for feedback on the position of the hydraulic ram cylinder.
Apart from the above-mentioned major parts, the system is equipped with high precision pressure and differential pressure transducers.
To achieve these objectives, a dynamic dual loop flow system was constructed, equipped with precision syringe pump, differential pressure transducers with data acquisition system and a DC power supply system with voltage regulator.
