Level measurement method using measurements of water column pressure therefor

摘要: For the apparatus and method to measure water depth level using a gas bubble type meter, measurement pipe for column pressure is composed of plastic pipes inside diameter 2-4 mm; two are bounded that elevation difference between ends Δh; upper connected buffer tank valves; sensor in temperature installed; supplying compressed with valve tank; outputs sent calculate specific gravity, level; calculating contains an convert displayed calculated values electrical or coded signals, store elevations lower pressure, measurements reference point measurement, pressures temperatures used at state gravity state; case automatic controller valves which long opened, supply closed short opened; Then, this significantly decreased error through compensation air (gas) (liquid). When measuring submerged sensors, measured by installing sensors interval Δh.
