HIGH SENSITIVITY LIQUID GASOMETER FOR FAMILY

The utility model discloses a high sensitivity liquid gas storage meter for family composed of a four way pipe [1] and a U-shaped pipe [2] communicated with the four way pipe [1]. An orifice [5] is positioned between the two branch pipes of the U-shaped pipe in the four way pipe [1]. Colored display liquid [3] is filled in the U-shaped pipe, and the height difference of the liquid columns in the two branch pipes of the U-shaped pipe [2] is approximately in the direct proportion to the square of the gas flow. Therefore, the height difference change of the liquid levels of the U-shaped pipe can exactly reflect the change of the flow to reflect the gas storage. The utility model has the advantages of high sensibility, simple structure and low cost. The high sensibility liquid gas storage meter for families is arranged on low-voltage gas conveying pipelines, and the high sensibility liquid gas storage meter for families is safe.
