Design of Oil-Water Interface Meter Based on Segmental Capacitance Sensors

Abstract

The technology of measuring oil-water interface height in oilcan has always been a critical and extremely complex problem. This paper introduced a system for measuring oil-water interface height based on segmental capacitance sensor which is constructed by 30 parallel capacitors, which were connected to a switch to low capacitance measure circuit .The changes in capacitance were measured and then sent to IPC to find the height of oil-water interface. Finally, the oil-water interface height meters examination system was constructed in laboratory and experimental results show that the design basically achieved the desired objectives and requirements.

Increasing the Sensitivity of an Optic Level Sensor With a Wavelength and Phase Sensitive Single-Mode Multimode Single-Mode Fiber Structure

“…In fact, many of these sensors can be found in nuclear facilities, bridges, swamps as well as naval ports, as examples of civil works where it is important to know the water level to avoid accidents [1]- [3]. Moreover, they are also present when monitoring the volume of liquids in hazardous applications such as fuel or oil storage [4].…”
