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...

The liquid flow measurement instruments are the devices used to evaluate the flow of water or any liquid in a conduit or an open channel. It is also used to calculate the precise amount of liquid present in the pipeline. These devices not only assess or audit the amount and flow of liquid but also are used to detect any wastage due to leakage. This measurement can be accomplished in various ways and in various mediums like pipelines, tunnels, tanks, natural resources, etc. There are various mechanical and technical instruments, which are used to measure the liquid flow, depending on the applications and type of liquid flowing. Various Categories of Liquid Flow Meter The various designs and technical aspects are responsible for the different designs of the flow meters, which have further variations. Water Velocity Measurement Meters : – This category consists of Vortex Shedding, Turbine, Swirl, Electromagnetic, Ultrasonic Doppler, Pilot Tubes, and Calorimetric. ...

Proteus Industries provides a reliable flow measurement solution to any oil, gas, liquid or steam operation. The quality of our flow meters can truly be seen at gathering facilities where a custody transfer of millions of gallons of products is required for transfer from one place to another on a daily schedule. An example of this is crude oil. A gathering station pumps up to 10,000 gallons of crude oil every minute. If a flow meter had a measurement error of just 0.02%, it will result in a loss of 68 barrels every day. A single barrel costs $40, so this will translate to a loss of $1 million every year. Taking steps to ensure that you are getting a reliable flow measurement solution is key to avoiding disastrous mistakes. One of accomplishing this is by taking steps to prevent measurement inaccuracy. This can be achieved by ensuring that instrumentation is calibrated properly before it enters operation. In today’s market, companies have access to numerous types of measur...

Flow meters are the equipment for the accurate measurement of the flow rate of the fluid passing through a pipe or an open space. The measurement can be made either on the basis of the mass flow rate or the volumetric flow rate. The rate of flow can be altered and distributed with the help of particular equipment called the flow control valve sensors. It provides accurate and programmable information, which helps in the execution of the distribution. Various industries have an abundant option of the control valve sensors to choose from. On the basis of the application and the purpose, the type of the sensors is chosen, which gives errorless productivity. Design of the Flow Control Valves The   flow control valve sensors   have diversified designs, from simple openings to refined electro-hydraulic valves. These different compositions of the valve sensors enable it to automatically adjust itself according to the change in temperature and pressure. The control valves are ...
