Ultrasonic flowmeter diameter, flow range, lining materials, electrode materials and output current, etc., can be adapted to the nature of the measured fluid and flow measurement requirements.
- 1、Precision function check accuracy level and function according to the measurement requirements and the use of occasions to choose the accuracy level of the instrument, to achieve cost-effective. For example, for trade settlement, product delivery and energy measurement occasions, you should choose a higher accuracy level, such as 1.0 level, 0.5 level, or higher; for process control occasions, according to the control requirements to choose a different level of accuracy; some just check the flow of the process, no need to do the control and measurement of occasions, you can choose a slightly lower level of accuracy, such as 1.5, 2.5 level, or even 4.0 level, then you can choose the inexpensive insertion ultrasonic flowmeter. Level, then you can choose the low-priced insertion ultrasonic flowmeter.
- 2、Measurable media measurement medium flow rate, instrument range and calibre measurement of general media, ultrasonic flowmeter full-scale flow rate can be in the measurement of media flow rate of 0.5-12m/s range of options, the range is relatively wide. Selection of instrument specifications (calibre) is not necessarily the same as the process pipeline, should depend on the measurement of the flow rate range whether the flow rate range to determine, that is, when the pipeline flow rate is low, can not meet the requirements of the flow meter or in this flow rate measurement accuracy can not be guaranteed, you need to reduce the calibre of the instrument, thereby improving the flow rate in the pipe, to get satisfactory measurement results.
