Water Flow Meter Principle

The flow principle behind magnetic flow meters is known as faraday s law mathematically defined as e k b d v.

Water flow meter principle.

The piston meter operates on the principle of a piston rotating within a. Each of these water flow meter types has a unique principle of operation overall cost of ownership and specific application benefits. When larger flow rates must be measured two or more flow meters mounted in parallel are required. A flow meter or flow sensor is an instrument used to measure linear nonlinear mass or volumetric flow rate of a liquid or a gas.

The induced voltage e is directly proportional to the velocity v of the fluid moving through the magnetic field b. Coriolis flow meters are not available for large pipelines. A mas s flow meter operating on the corioli s principle c ontain s a v ibra ting tube i n which a fluid flow caus es changes i n frequen c y phase s hift or am plitude. Coriolis flow meter principles the basic operation of coriolis flow meters is based on the principles of motion mechanics.

They operate based on the principle that water passing through a known cross sectional area having a measured velocity is proportional to the volume of water flow. Water flow sensor consists of a plastic valve from which water can pass. Several water flow meter technologies are available for selection depending on the water measurement applications budgetary terms and maintenance requirements. Rate of flow of water is measured as liters per hour or cubic meters.

Because they are used for domestic water measurement piston meters also known as rotary piston or semi positive displacement meters are the most common flow measurement devices in the uk and are used for almost all meter sizes up to and including 40 mm 1 1 2 in. Conversely decelerating fluid moves away from the point of peak amplitude as it exits the tube. Velocity meters measure the velocity of the water flow and convert it into the amount of water flow. The largest coriolis flow meter that is currently available has a maximum flow rating of 25 000 lb min 11 340 kg min and is equipped with 6 in.

Water flow sensors are installed at the water source or pipes to measure the rate of flow of water and calculate the amount of water flowed through the pipe.
