自动剂量王Kamoer已经推出了一个名为X2SR的重型水分设备。两个大型步进电动机通过在移动应用程序上进行Wi-Fi控制来实现可编程水的变化，并且它们能够每小时交换多达54升（14加仑）。就像智能剂量的剂量一样，X2SR的应用程序可以调整整天或一周的多次换水计划，甚至可以调整量，甚至可以告诉您您要抽水的水库中剩下多少水。
超级准确的草原使得可以同时以同步模式同时将相同的水量拉入并从珊瑚礁系统中撤出进出模式。可以对头部进行校准，以持续整个设备的生命。
In-built flood prevention
But reefers know two potential problems could occur with doing saltwater water changes when you’re not there. The first one is evaporation – that age-old reefkeeping conundrum whereby simply replacing old seawater with new doesn’t account for the loss of freshwater via evaporation. If it tops up evaporation with saltwater salinity rises. If aseparate ATOisn’t turned off during “out” mode it will kick in and start to top up with extra fresh, taking salinity down.
And secondly, what happens if something goes wrong? We all know the potential hazards with open-topped sumps and reservoirs if one dumb device pumps too much into the other and doesn’t stop. One runs dry and one floods.
But the X2SR addresses all these issues by way of its own, included, ATO with a separate pump, and not one but four separate level sensors. One sensor is placed in the pump chamber of thesump就像使用普通的ATO传感器一样。然后将一个放在ATO储层中，以提醒并防止干燥。然后将第三个传感器放置在污水池中，以提醒水底运行水平是否高于正常水平，并将第四个传感器放置在废水储层中，以提醒那里的水平太高。运行灾难场景，四个传感器应阻止这种情况完全发生。
We are aware that this can also be achieved with some already available monitoring and control systems, and that they could even switch complete pumps off by way of controllable plug bars. But with the X2SR Pro, you don’t have to buy into an extra, separate control system, and everything you need comes in one, neat, autonomous package. There are inbuilt buttons for a swift manual water change if desired too.
Size is everything
第一次将目光投向肉体中的X2SR时，您会注意到它比任何标准的自动剂量器都比任何标准的自动剂量更大，更强大。头部需要更大，以使大量的水交换，尤其是在大礁系统上，连续运行甚至可以使每天交换1200升（317加仑）的水。这也提供了专业的商业应用程序，使其适合于在商店珊瑚托盘甚至批发鱼类系统上工作。Extra noise does come with extra size, however, so although you probably wouldn’t want it operating right next to you while you’re watching tv, it could be placed a considerable distance away in your garage, (its powerful enough,) or you could program the unit to do the water changing while you’re out of the house.
能够在不影响盐分的情况下自动换水的梦想与爱好本身一样古老，而Kamoer X2SR则提供了这种方式。更换足够的水，您将保持低硝酸盐，补充所有这些微量元素，甚至根本不需要补充剂量。稀释可以是污染的解决方案，使用此设备，您甚至不需要弄湿。我们完全期望大多数礁会与使用的ATO同步模式下运行它，并将在机柜的一侧放置一块新的新水，另一侧为废水放空。而且，如果它太重了，价格过高，价格为479.99英镑/$ 643.91，那么一个较小的，虽然较小的小兄弟，但称为Kamoer X2S。
