Different Types of Water Meters 1. The device doesn’t have any moving parts and cannot work with hydrocarbons and distilled water. The red hand is called the sweep hand, and the small white triangle is called the flow finder. The meter only records the water used. Types of water meters explained 1. The Paddlewheel sensor is a cost effective and most commonly used water flow meter. Your meter is read monthly and each month you receive a water/sewer bill based on the amount of water you use. 2.3 Venturi Flow meter The venturi flow meter, while considered an obstruction flow meter, is less of an obstruction than the orifice type. 1. Water velocity or current meters. A wide variety of types of water meters options are available to you, such as multi-jet meters, ultrasonic meters, and turbine meters. type meter . Continuous further development guarantees the most precise measurement results and the best long-term stability. There are several working principles to choose from, depending on the application, maintenance needs, and budget. The volumetric flow rate of the water is proportional to the rotational speed of the blades. It will make contact with a limited cross-section of the flow. There are several types of meters that measure water flow velocity, including jet meters (single-jet and multi-jet), turbine meters, propeller meters and mag meters. The meter can not distinguish how the water is used. Different Types of Flow Meters & Their Applications Flow Meter requirements vary, from mass flow to volume flow and beyond. The four most common water flow meter types are turbine (also called mechanic), vortex, ultrasonic, and electromagnetic. Water meters are classified as class A, B, C and D. Class A and B are widely available and used in India. 2.10 Water Meter, Wet-Dial Type— Meter in which the complete counter unit is in contact with water flowing through the meter. A water meter is a type of flow meter which is used to monitor the flow rate of water through a pipe. • Among the types of water meters are those that differ in the method used to measure water volume, and the flow control and measurement devices in the water meter itself. B.
