Flow measurement is a highly theoretical and technical subject. However advanced the technology, the basic accuracy of meters and metering equipment must not be discounted. Drinkwater Products is involved with very basic equipment for liquid measurement using pipe provers, namely prover spheres and prover detector switches. As basic as these may be, it is essential that they be of the best quality and accuracy. Anything short of this opens the door for potential losses. With the view that measurement is your "cash register", we strive to do our part in offering the very best products.
