flow meters

When selecting a flow meter （ Magnetic, Ultrasonic and Coriolis mass ） , follow the steps below: www.rbflowmeters.com 【 1 】 First, it is necessary to confirm the properties of detection fluids. Fluid types Gas, Liquid, Vapor, etc. Density Can be calculated from fluid name, temperature and pressure Viscosity Required for liquids Electrical conductivity Required for electromagnetic type flow meters Contaminants Air bubbles, mixed-in foreign objects, slurry, etc. Flow range Minimum and maximum flow Fluid temperature Measured in response to the fluid Fluid pressure For pressure-resistance confirmation Pressure loss Measured as necessary 【 2 】 Next, clarify the purpose of measurement. At this point, determine a selectable detection system along with properties such as accuracy and flow range 【 3 】 Once t...

Top Tips for flow meter selection The huge array of flow technology options on offer can make selecting the correct flowmeter for an application a bewildering task. A broad range of factors can influence flowmeter selection, of which cost is just one. Dr Bryan Franklin, Flow Products Manager, ABB Limited recommends a list of top tips for selecting the best all round flow system for an application. 1. Do you even need a flowmeter? Many users often just want to know the rate at which a liquid or gas is moving through a pipeline. In such cases, a simple flow indicator, available from any flowmeter vendor at a fraction of the cost of the simplest flowmeter, will usually suffice. Simple and easy to install and requiring no external power, these instruments can be used to provide local indication of flow. Even where there is a demand for something more sophisticated, such as an indication of flow to within 10%, there may still be no need to purchase a flowmeter. Many installations ty...
