Clean or dirty Wet or dry Hazardouscorrosive or safe Single or multi phase Laminar of turbulent Varying. Basic Flowmeter Principles How They Work Flowmeters are used in fluid systems liquid and gas to indicate the rate of flow of the fluid. This is also the reason that the next flow meter type was developed.

Estimates are that over 50 percent of all liquid flow measurement applications use this type of unit. Among the major types of measurement devices. There are several types of flow measurement devices currently in use across the United States by private local state and federal agencies.

An annubar is another type of meter that can be inserted into a pipeline for accurate measurement of the flow rate. Types of Flow Meters. 11 Introduction to flow meter reference design Flow meter based on MC9S08GW64 is a low-cost low-power system.
