Pitot Tubes or Differential Pressure Sensor for Liquids and Gases The pitot tubes offer the following advantages easy, low-cost installation, much lower permanent pressure loss, low maintenance and good resistance to wear. Wide Rangeability Rangeability is defined as the ratio of maximum value to minimum value of the measureable range.

The meters consists of a multi-bladed rotor mounted at right angles to the flow and suspended in the fluid stream on a free-running bearing. See More Flow Meter Models. Thank you for your inquiry and interest in ABB. Emerson is where technology and engineering come together to create solutions for the benefit of our customers, driven without compromise for a world in action.

What are the advantages of using Vortex Flow Meters?

A minimum of 10 pipe diameters of straight pipe on the inlet is required. Those “inexpensive” purchases can be the most costly installations. Version matrix Software and documentation: Models are available with temperature and humidity measurement. Flow Measurement in History Our interest in the measurement of air caudalimtro water flow is timeless. For these reasons, they have been gaining wider acceptance among users.

In some applications, measuring the volumetric flow is the thing to do. What is the minimum and maximum process temperature?

How We Use Cookies: Ultrasonic flow meters The ultrasonic doppler flow meters are commonly used in dirty applications such as wastewater and other dirty fluids and slurries which ordinarily cause damage to conventional sensors.


This frequency is called the Karmen Vortex Frequency. Poorly selected devices invariably will cause problems at an early date. Knowledge caudqlimetro the direction and velocity of air flow was essential information for all ancient navigators, and the ability to measure water flow was necessary for the fair distribution of water through the aqueducts of such early communities as the Sumerian cities of Ur, Kish, and Mari near the Tigris and Euphrates Rivers around 5, B.

Anemometers for Air Flow Measurement Hot wire anemometers are probes with no moving parts. Because point sensors do not look at the full flow, they read accurately only if they are inserted to a depth where the flow velocity is the average of the caudakimetro profile across the pipe. Displays are integral or an analog output can be used for remote monitoring or data logging.

Output is Proportional to Flow Rate Since the output is directly proportional to the flow rate flow velocityno square root calculation caudalimeyro needed, while orifice flow meters require square root calculations. The accuracy requirements should be separately stated at minimum, normal, and maximum flowrates. Volumetric flow measurement would seem applicable.

This oscillation is equal to the Karmen Vortex Frequency. Mass or Volumetric Caudalimtero Before specifying a flow meter, it is also advisable to determine whether the flow information will be more useful if presented in mass or volumetric units. Moving parts are a potential source of problems, not only for the obvious reasons of wear, lubrication, and sensitivity to coating, but also because moving parts require clearance spaces that sometimes introduce “slippage” into the flow being measured.

Flow Meters

Choose the right flow meter. These instruments are designed to be flexible and reliable in harsh process environments. In other applications, repeatability may be more important than absolute accuracy. ABB offers software tools that use the listed drivers above for your device configuration and monitoring requirements.


This low pressure produces a differential pressure dp across the shedder bar. In view of these considerations, mass flow meters, which are insensitive to density, pressure and viscosity variations and are not affected by changes in the Reynolds number, should be kept in mind. The major factor, of course, is matching the right instrument to the particular application.

Industrial flow measurement Basics and practice. Even if this point is carefully determined at the time of calibration, it is not likely to remain unaltered, since velocity profiles change with flowrate, viscosity, temperature, and other factors.

Since only the vortex shedder is placed in the pipe of the vortex flow meter, the fluid pressure loss due to the small restriction in the flow piping is small compared with flow meter a having an orifice plate. Whether flow can reverse, whether it does not always fill the pipe, whether slug flow can develop air-solids-liquidwhether aeration or pulsation is likely, whether sudden temperature changes can occur, or whether special precautions are needed during cleaning and maintenance, these facts, too, should be stated.
