Liquid Flow Meters and Switches

Liquid velocity flow meters are used when it becomes necessary to calculate the volumetric flow rate of a stream. A velocity flow meter calculates flow by computing the speed in one or several points in the flow and assimilating the flow speed over the total flow area. Velocity flow meters are commonly used in industries because they provide a nonstop measurement of fluid velocity; a trait commonly associated with flow rate. This type of flow meter is one of the most sensitive to processing conditions. Liquid velocity measurement meters function under the theory that there is a constant velocity profile. As a result, they are erroneous in the laminar regime. Inaccuracy occurs due to the large difference between fluid velocity at the center of the pipe and near the wall. As a result, velocity flow meters are very sensitive to Reynolds numbers and piping geometry. Examples of liquid velocity measurement meters include turbine, paddlewheel, electromagnetic and vortex s...

Water flow meters are used to measure the volume of water used in commercial and residential buildings. The water is supplied to homes and offices via a public water supply system. Water meters may also be used at water sources or throughout the water system to calculate the flow rate of a part of the system. Water flow meters may also measure the flow rate of slurries or fluids in closed pipes. The flow rate of water is measured in cubic metres (m3) or litres on an electronic or mechanical register. Water flow meters can measure hot water, cold water, clean water, dirty water and slurries.  Two common methods are used in water flow meter measurement: velocity and displacement flow meters. Each type takes advantage of a variety of technologies. Paddle Wheel Water Flow Meter The Paddlewheel sensor is a cost effective and most commonly used water flow meter. It may also be used to measure flow rates of water-like fluids. Many paddlewheel sensors are sold with ins...

With the wide variety of options available in the market, it can sometimes be difficult selecting the right flow meters and switches for your application. We are using this blog to inform you about the features, advantages, and difference of flow meters and switches. To make an informed decision, you should know about the basics of flow meters and switches. Let us go in-depth about both the flow measurement devices. How are Flow Meters Different from Flow Switches? The difference between the two devices lies in the way they function. Flow meters are used to monitor the flow rate; the user has to manually check the flow rate to detect any problems. Whereas, flow switches are used to check the presence of flow and alerts the user at a predetermined set point, and perform action. What is a Flow Switch? A flow switch is an automatic device that controls the flow of liquid, air, and steam. The device works by sending trip signals to another device such as ...
