Effective immediately, we will have a new Flowhub available for order with a new part number (P21000014). The new Flowhub will look similar to the current Checkhubs. The Flowhubs will have a label on the top so you can distinguish between the Checkhub and the Flowhub. (See image to the right). You can also tell the difference by looking at the openings. The inside of the Checkhub will look black and the inside of the Flowhub will look white.
