This task is done in an organized manner by creating forms that these data types are going to be entered in each application: Fluid and Flow Characteristics The piping system that the fluid will flow through also needs to be stated. When all these are addressed, what follows is an evaluation of the fluid flow properties. If it is going to be shared, what will be the min and max data update frequency required. Should it be done locally, will it be transmitted digitally or analog, or shared. One should also know whether the info given will be relayed remotely or locally. Knowing whether the flow rate data will be continuous or totalized is the first step in picking the right flow meter or sensor. The Main Step to Choose the Right Flow Meter Q denotes the volumetric flow rate, and ṁ denotes the mass flow rate in the equation ṁ=Q x ρ. Both volumetric mass rates are related to the density of the fluid. Volumetric flow rate and mass flow rate are units used to measure gases and liquids. The type of airflow meter is based on its application. What is the Purpose of a Flow Meter?įlowmeters are used to measure the mass flow rate or the volumetric flow rate of a fluid in many types of applications. A flowmeter may consist of one or many physical devices since these components are most of the time combined. Raw signal from the transducer is then turned into usable data by the transmitter. The work of the transducer is to sense the fluid passing the primary device. Most flowmeters have three parts: the primary device, a transducer, and a transmitter. Other flowmeters are meant to count the total amount in liters of fluid that has gone through them (such as 100 liters). Some flowmeters are meant to measure the fluid amount flowing inside them after a period of time (100 liters per minute, for instance). Flow Measurement Overviewįlowmeters are tools used to monitor the amount of vapor, liquid, or gas passing through them. In other words, a flow meter is a tool used to measure either mass or volumetric flow rate or the amount of fluid flowing inside a pipe. This data is vital because it determines whether the company makes profits or PV6000 Seriesloses. In plants that make or use fluids, getting the flow rate is crucial. Does it know how to maintain and calibrate the device? What about the meantime failure history? Are spare parts easy to get based on the plant site? After going through all these, the next step is to compute the setup cost. These factors include whether or not the personnel is familiar with the plant. Before choosing a flow meter to use in an application, a few factors need to be considered. It measures the volumetric or mass flow rate of gases or liquids. Malema's customer support and application engineers are well trained and are ready to offer you the guidance when requested to select the right flow meter product to suit the application.Also known as a flow sensor, a flow meter is a device designed for measuring nonlinear or linear flow rate. Malema offers inline straight tube, U and Z style ultrasonic flow sensors.Īs there is no single flow meter technology that can cover all of the application needs, Malema offers its customers the following wide choice of flow meter technologies to choose from. Malema’s ultrasonic flow meter range offers high accuracy and repeatability performance specification for measuring liquids and slurries with the help of the most advanced filtering and digital signal processing techniques used in the industry.
