These are needle gauges that can be modified to fit any banana plug on any low cost flow meter such as B. the Cen-Tech models, which were available for about the same price. The cheap gauge clues seem to be the weakest part of the deal, so they're the solution to the useless clues that come with your cheap gauge. Replace the protective caps on the sensors as they are sharp unlike the OEM tips. May the electromotive force be with you.
