How to choose a reliable flowmeter

How to choose reliable flowmeter, metering is the eye of industrial production.Flow measurement is one of the components of metrology science and technology. It is closely related to national economy, national defense construction and scientific research.To do this work well, to ensure product quality, improve production efficiency, promote the development of science and technology have an important role, especially in the energy crisis, the degree of automation of industrial production is increasingly high nowadays, the position and role of the flowmeter in the national economy is more obvious.

The commonly used unit m3/h in engineering can be divided into instantaneous FlowRate and TotalFlow. The instantaneous flow refers to the amount of effective section of closed pipe or open channel per unit time.Cumulative flow is the cumulative flow of fluid through the effective section of a closed pipe or open channel at an interval of time (one day, one week, one month, one year).The accumulative flow can also be obtained by integrating the instantaneous flow against time, so the instantaneous flow meter and the accumulative flow meter can also be converted into each other.

Here are three steps to choose a solid flowmeter.

Step 1: see what you need - each flowmeter has different characteristics according to the type of product and the nature of the medium suitable for measurement.At present, although the development of flowmeter measurement technology has become more and more mature, but the variety of flowmeters, no flowmeter is suitable for any occasion, each flowmeter has a certain range of applications and limitations.When choosing the type, we can first judge the flowmeter that can be used according to the nature of the medium under test, and then choose the instrument suitable for field conditions according to the working conditions and flow range.

1. Selection of gas flow meter: 1. Gas turbine flow meter.2. Vortex flowmeter.If the gas temperature exceeds 300, a differential pressure flowmeter can be selected.

Ii. Selection of large tap water flowmeter: suitable for liquid turbine flowmeter, electromagnetic flowmeter and ultrasonic flowmeter.

Iii. Selection of turbidity liquid flowmeter for sewage and pulp:

1. Doppler ultrasonic flowmeter and electromagnetic flowmeter can be used.However, when choosing electromagnetic flow timing, consider that the liquid does not contain more air or bubbles.

2. Meter options for liquids with more bubbles: doppler ultrasonic flowmeters can be used.This type of flowmeter is used to measure fluid with bubbles.It works really well.

3. Choose flowmeters with low conductivity, such as pure water and softened water: ultrasonic flowmeters are ideal for measuring this fluid.

Porcelain city of all flowmeters, small to a screw hole, large to the case and gear are using Germany Siemens CNC machining center to complete, completely get rid of the current domestic mechanical and manual mixing operation of the manufacturing process, elliptical gear manufacturing process will produce a milestone change.
