This logo is shaped like a black and white gauge with a lot of different lines for measurement. There seems to be some liquid about halfway up it. There is also a droplet or something coming out of the bottom.
This is a Rain Gauge icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
