![]() These kinds of flow meters are undesirable in applications that require maximum pressure throughout the system. The obvious downside of this type of flow meter is that it reduces pressure and can slow down water flow, causing permanent pressure loss. A high pressure drop indicates high water flow. Differential Pressure Flow MetersĪ differential pressure flow meter forces water through a constriction of some type, such as an orifice or nozzle, and measures the water pressure on both sides of the constriction. That means there is no degradation in flow during the measurement process. In addition, because there are no components directly in the path of the water, electromagnetic meters don’t impede water as it passes through. By sensing the voltage generated by water as it passes through the magnetic field, electromagnetic flow meters can track flow rates with a high degree of accuracy.Įlectromagnetic flow meters are generally low maintenance, because they have no mechanical parts that can break down. The electrodes, which are embedded on opposite sides of the surface through which liquid flows, create a magnetic field. Electromagnetic Flow MetersĮlectromagnetic flow meters, sometimes called magnetic meters or mag meters, use electrodes to measure water flow. ![]() However, several different types of flow meters exist, each of which uses a different approach for tracking flow. Help factory operatorsassess the amount of water being used to cool an industrial plant.Īll flow meters perform the same basic job: They measure flow by tracking how much liquid or gas moves through a fixture in a given period of time.Track sewage flowto help municipalities ensure that their wastewater systems adequately meet demand.Measure usageby individual households or communities within municipal drinking water systems.Water flow meters can be used to track the flow of water within a variety of applications. In turn, they help operators determine whether systems are properly balanced, ensure that each endpoint receives adequate supply, identify excessive flow rates that could damage pipes, and so on.Ī water flow meter is a flow meter designed to measure the flow of water specifically, as opposed to other types of liquids (like oil or gasoline) or gases. What is a Flow Meter?Ī flow meter is a device that measures how much liquid or gas moves through a pipeline in a given period of time.īy measuring flow rates, flow meters provide crucial visibility into what’s flowing where, within pipes, drainage systems, and other types of infrastructure. Below, we explain how flow meters work, what types of flow meters are available, and how to select the best flow meter for your needs. ![]() That’s why flow meters are an essential tool across a variety of industries today.īy delivering accurate, continuous visibility into flow rates - flow meters ensure that agencies and businesses have the information they need to maintain smooth operations and meet regulatory requirements. You must be able to measure what’s flowing where on a continuous basis. Download as a PDF documentįrom agriculture, to manufacturing, to the oil and gas sector, and beyond, flow meters play a vital role in ensuring safe, reliable operations of critical liquid and gas infrastructure.
