So let's just calculate, given this small additional pressure, how high is the liquid going to go, above the level of the solution.
现在我们计算一下,对于这样一个小的多余的压强,液体相对于溶液的,液面能有多高。

According to this, conducting liquidlevel can be gauged by measuring the conductance of the liquid with a pair of electrodes and this method has been proved to have a relative high-accuracy.
