📏 DIGITEN Connect Flowmeter Counter 0-3-10L: Accurate Test, Measurement & Inspection Review

I can't get this to work with DIGITEN for the controller. I'm not sure why it isn't read. I don't know what value of k I should put in for this thing to work very frustrated.

I originally gave this product 1 star because it does not offer fast connections as advertised. However, the seller contacted me and offered either a replacement or refund and due to the seller's willingness to work with me to resolve this issue, I am increasing it to 3 stars.

I have updated this review and removed what I had previously. While I've had trouble letting air through, as the seller pointed out here, it's not designed for airflow. Once I started pumping water through I had no issues with the spinner inside. The fault was mine, but the product is good!
