All cold water meters (displacement type - magnetic drive ñ⁄” - î”) furnished shall be produced from a manufacturing facility whose QMS is ISO 9001 certified, conform to the “Standard Specifications for old Water Meters” ó ì ì latest revision issued by AWWA. Mechanical meter performance depends on the inertia of the rotor, friction in The rotor of the paddlewheel sensor is fitted perpendicular to the flow rate. There are several working principles to choose from, depending on the application, maintenance needs, and budget. It may also be used to measure flow rates of water-like fluids. NOMINAL SIZE 3.1 The water meters shall be of the following nominal sizes: The meter only records the water used. A meter must be matched to the system, and the water user has to tell the meter dealer the following basic information to make sure a meter … Types of Water Meters Explained 2. A water flow meter measures the amount of water flowing through a pipe. The following are the different kinds of water meters that are designed to observe specific characteristics of water. MNK is an MID com-pliant water meter, proven by the million, for service connection. The mechanism is calibrated by an adjustable device that is preset and security sealed. These meters are designed to keep track of how much water is consumed by a particular household or business. Types of Water Meters ALWAYS ENSURE THAT THE METER IS INSTALLED TO MEET THE CONDITIONS OF YOUR RESOURCE CONSENT. B. The District has embarked on water a meter replacement (WMR) program to replace existing water meters that are 20 years and older. Displacement, single-jet, electronicor turbine meters. Mag flow meters are also easy to maintain. Inferential type flow meters.
