Rosemount Flowmeter Selection Flowmeter How to Select Type

How to select the type of flowmeter? When selecting the type of flowmeter, it is necessary to fully consider various factors to ensure application. In order to help everyone solve the problem of how to select a flow meter, the following content is summarized for reference.

In the question of how to select the type of flowmeter, the selection methods and reference factors of different types of flowmeters are not the same, and they should be selected according to their specific roles and performances.

1. Electromagnetic flowmeter selection

Measure various kinds of acid, alkali, salt and other corrosive liquids; various flammable and explosive media; various industrial sewage, pulp, mud and so on. Electromagnetic flowmeters cannot be used to measure gases, vapors, and liquids containing large amounts of gas. They cannot be used to measure liquid media with very low electrical conductivity and cannot measure high-temperature, high-pressure fluids.

2. Vortex flowmeter selection (vortex flowmeter)

Vortex flowmeters are mainly used for the flow measurement of medium fluids in industrial pipelines, such as gases, liquids, and vapors. Its characteristics are low pressure loss, large range, high precision, and almost no influence of parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow.

3. Float Flowmeter Selection (Rotor Flowmeter)

It can be used to measure the flow of liquids, gases, and steam. It is especially suitable for measuring medium flow at low flow rates and small flows. 4. Coriolis mass flow meter selection

Mass flow meters are widely used in petrochemical and other fields and are one of the leading flow measurement instruments in the world today.

5. Thermal (gas) mass flow meter selection

Suitable for single gas and fixed ratio multicomponent gas measurements.

6. Ultrasonic flow meter selection

At present, China can only be used to measure fluids below 200°C. Strong corrosive, non-conductive, radioactive and flammable explosives flow measurement problems.

7. Turbine flow meter selection

Turbine flowmeters are widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, gas, and cryogenic fluids.

Flowmeter selection cannot be perfect, because each type has its own advantages and disadvantages. It can only be selected according to different measurement methods and structures, requiring different measurement operations, methods of use, and conditions of use to choose reliable and economical Durable style.

The following preparatory work must be done before selecting the flowmeter: 1. Name and characteristics of the fluid to be measured (corrosiveness, viscosity, abrasion, etc.) 2. Work flow (normal flow, maximum flow, minimum flow) 3. Work pressure (Maximum and minimum working pressure), if there is a negative pressure formation to pay special attention 4, the working temperature (the highest temperature, the lowest temperature) 5, the conductivity of the fluid, the required must have a certain conductivity, conductivity ≥ 5μS/cm 6, Installation location 7, power supply method 8, process piping size 9, communication with the central control room

    ●    Used in aeroengine oil system.
