Abstract: During the cold season of the year when gas measurement and flow are most critical, the measurement men may be plagued with the problem of hydrate formation in orifice meters, meter runs, piping and regulators. Hydrates are solid compounds formed by the union of water and hydrocarbon molecules under conditions of high pressure and low temperature. The accumulation of these solids restrict the flow of gas through regulators and meter runs and, also, give false indications of measurement by plugging lead lines to orifice meters and by changing the internal characteristics of the meter tube.
