Choosing Type of Flowmeter
Models and types of flow meter that populated the market is quite varied where types can be adjusted to flow meter’s functions and flow meter’s applications in the field. These matters are worth noticing to be used as our referrence when choosing types of flow meter that suits our needs.
Choosing types of flow meter must be suited with what we need and what to achieve, fluids specification and method. Depends on the flow meter methods, can be divided into some type of flow meter:
There are numerous company that tried to develop this technology to be applied on steam, but so far the application of this tool is still uncommon and very limited. Ultrasonic flow meter so far has been made in various types and applications ranging from transmit time or Doppler as base flow or liquid flow, low anemometer to describe the high cost of natural gas as a housing transfer application. The price for an ultrasonic flow metercan range from USD 25 to USD 150,000 depending on the application, and there are also hand held ultrasonic flow meter.
Prinsip of Operation of Ultrasonic Flow Meter
Basically people will distinguish one technology from two types of measurement techniques but this is not entirely true. An Ultrasonic flowmeter will be categorized into Doppler type (which is used to shift the Doppler principle). Or time transfer equipment in the form of measuring time difference.
This difference may have brought a fairly simple reason to easily classify ultrasonic in the industry. If someone learns ultrasonic flowmeter measurement techniques, they will find that some technologies are still not suitable to be used.
Principal used in Doppler flow meter meter has Doppler shift which measures using continous wave in constant frequency or variations such as changes happening inside the Doppler shift is measured using vibrations.
This type of flow meter ultrasonic is quite popular especially for those who want the type of flow meter that can be moved around or in other words it is portable and it is also referred to as a hand-held flow meter. Its operation method is quite simple, just clamp it on to the pipe which flow is going to be measured.
