Embodiment 1
[0048] refer to Figure 1~4 , this embodiment provides a surface impurity removal system for gas field flowmeters, including a main system S1, including a pipeline module 100 and a control module 200, wherein,
[0049] The pipeline module 100 includes a first air inlet pipe 101, a measurement circuit 102 and an air outlet circuit 103. The first air inlet pipe 101 and the measurement circuit 102 are connected at the first interface A, and the air outlet circuit 103 and the measurement circuit 102 are connected at the second interface B and connection at the third interface C;
[0050] The control module 200 includes a first valve 201, a second valve 202, a third valve 203, a fourth valve 204 and a fifth valve 205. The first valve 201 is set on the first intake pipe 101, the second valve 202, the third valve The valve 203 is set on the measuring circuit 102 close to the first interface A, and the second valve 202 and the third valve 203 are set at both ends of the first interfa...
Embodiment 2
[0064] refer to Figure 1~6 , the present embodiment provides a method for removing surface impurities using the above-mentioned surface impurities for gas field flow meters, which is implemented by using the above-mentioned surface impurities removal system for gas field flow meters, as follows:
[0065] When the main system S1 is working, open the first valve 201 to select the main system S1 to work, and close the sixth valve 401 of the backup system S2;
[0066] Send the measured flow into the first air intake pipe 101, adjust the switch of the control module 200 to make the measured flow pass through the flow meter 102d forward or reverse;
[0067] Switch the valve switch to close the first valve 201, open the sixth valve 401 to work in the standby system S2, and clean the main system S1;
[0068] Start the cleaning pump 300, deliver the flushing fluid to the measuring circuit 102, and adjust the switch of the control module 200 so that the flushing fluid passes through t...
