Getter filter is one of the ancillary equipment flowmeter, which has separate gas pipeline flowing medium, filter impurities in the medium, so as to ensure the flow meter measurement accuracy and prolong meter life. Later when the refined oil from the inlet inflow by placing the barrel in the filter, the removal of solid impurities, liquid through the filter component, change the direction of flow, so that the free gas oil varieties and partially dissolved gas ran out fully, gas rose to the top of the separator, a gas space appears hydrocarbon interface. With the increase in pressure increases the volume of gas to increase oil and gas interface decline, down to a certain extent the current float means is operated to open the valve of the gas excluded, rising oil and gas interface, the gas space narrowing float valve means is closed , so that flow through the filter media getter reached the oil, gas, solid three separate purposes.

Installation and maintenance:
1, Getter filter should be installed vertically in front of the meter, the same direction with the flow direction arrow on the housing.
2, before using the exhaust valve to open, to ensure that the air flow before entering the meter can be smoothly discharged.
3, the filter should be cleaned regularly, in order to reduce the pressure loss and ensure the filtering effect.
4, the exhaust filter if a small amount of hydrocarbon foam discharge is normal, when the discharge of oil and gas foam affect the surrounding environment, can a hose to the exhaust valve outlet connected to the oil and gas import oil foam cylinder.
5, if a large number of oil discharge is not normal behavior, shall be closed to cool down the exhaust filter, close the valve on the downstream, folding open eliminator filter maintenance.
