36. water pressure is therefore same at both ends of the tube By measuring the pressure at the dry end the pressure at the submersed end is determined A simple calculation using pressure to head of water conversion is then made to determine water level A practical gas purge system consists of several components Firstly a compressed gas is required for which low cost dry nitrogen is typically used Nitrogen bottles are filled are at high pressure around 15 20MPa 2000psi hence a bottle regulator is used to reduce the pressure to around 400kPa 60psi Gas is fed into a gas purge regulator also called a constant differential flow regulator as it regulates the flow with varying backpressure Next a capillary tube is required to carry the gas to below the water surface One end is connected to the flow regulator output while the other is installed under the water surface to be measured The gas purge regulator is adjusted to produce a very low flow rate of approximately 50 cc hour The flow of gas is so low that it is always laminar producing only negligible friction effects This is important as it results in almost zero pressure difference between tube ends even if small internal diameter tube is used Lastly a pressure sensor is connected to the dry tube end for measuring the pressure in the system Pressure is converted to level using liquid density and a standard for kPa to level conversion The levelpro 6100 is designed to operate with all type
