Primary flow element. A primary flow element is the element of a flow meter that serves to indicate the quantity or velocity of flow. For example, in the case of an orifice flow meter, the differential pressure across the orifice plate is the primary flow element.
Some of the most popular flow meters are: peak flow meters, water flow meters, fuel flow meters, air flow meters, ultrasonic flow meters and flow monitor services. Many flow meters measure the volume of the material while other flow meters measure the speed, and still other flow meters measure the mass of the materials.
