This invention relates to portable flow measurement device. Portable flow measuring device according to the invention geophysical logging data acquisition, and use mode to perform a search using a flow meter for measuring the flow rate of pumping in the borehole, posture between the mobile mode to move to carry the flow meter changeable An apparatus, a portable flowmeter is placed between the mobile mode, disposed on both sides of the portable flowmeter mutually detachably first support member and the second support member is coupled, in a mobile mode interval between the first support member and second support member such that the first support member is formed with a plurality of spacing members are interposed between the second support member, coupling means for coupling the first support member and the second support member in a moving mode, and a flow meter to enable mutual detachable from the mode is characterized in that the first support member is coupled to a mounting means for the support to be mounted on the second support member which lie on the ground in a state arranged in the vertical direction. ; 展开▼
