一、概述 目前广泛应用于水文地质、工程地质勘察中的流速仪、流量计、测漏仪、孔口流速仪等,经过实验标定以后,只能反应出孔内液体流速或流量,但不能同时显示液体的流向。尤其是在水文地质井孔中,利用上述仪器判别上下含水层的互补关系是比较困难的。然而钻孔可逆流速仪却具有下列特点; 1.经过实验标定后,可以反应出孔内液体的流速或流量。
I. Overview Currently widely used in hydrogeology, engineering geology survey in the flow meter, flow meter, leak detector, orifice flow meter, after the experiment calibration, can only reflect the liquid flow rate or flow within the hole, but not at the same time Shows the flow of liquid. Especially in hydrogeologic wellbore, it is more difficult to determine the complementary relationship between the upper and lower aquifers by the above instruments. However, the reversible flowmeter has the following features: 1. After experimentally calibrated, it can reflect the flow rate or flow rate of the liquid in the hole.
