Accurate flow measurements of gases and liquids are required for better. A float rises inside a conically shaped glass tube as the flow increases, and the position of the float on a scale can be read off. It provides flow measurement of liquids, gases, and steam. It requires no power and has a visual indicator. Flow meters are also known as Flow Gauges or flow measurement instruments. Variable Area Flow meters, also known as Rotameters, are a simple and versatile method of flow measurement. Flow meters are flow-measuring instruments used to measure the linear, nonlinear, mass, or volumetric flow rate of a gas or a liquid. You may have heard of them being referred to as a flow meter or flow indicator. A flow meter is a device that measures the flow rate of a fluid. See More Differential Pressure (DP) Flow Simplify flow measurement with streamlined, cost-effective devices. These flowmeters, as well as rotameters, must be calibrated against a primary standard to verify accuracy. Flow sensors are devices that help us measure the movement of fluids, like water or air, in various applications. Rotameters (Variable Area Flow Meters) Variable area flow meters, or rotameters, are some of the oldest devices used for flow measurement, known for their flexibility across various applications and high reliability. The ball-type flowmeters and rotameters built into most air sampling pumps are intended to serve as flow indicators and are, therefore, of low accuracy. A flow meter (or a flow sensor) is an flow instrument that is used to indicate the amount of liquid, gas, or vapor moving through a pipe or conduit by measuring linear, non-linear, mass, or volumetric flow rates. Rotameters are secondary calibration standards used to obtain accurate, reliable measurements of pump airflow rates if calibrated to a primary calibration standard on a regular basis. As one of the industry’s most trusted flow meter companies, our measurement and. KROHNE Group offers a range of rotameters, or variable area flowmeters, for simple and cost-effective flow measurement of gases or liquids without auxiliary power.
