First, the power supply method is different: the fixed ultrasonic flowmeter requires long-term continuous operation, so the use of 220V AC power supply, portable ultrasonic flowmeter can use on-site AC power supply, but also contains built-in rechargeable batteries, can work continuously for 5 to 10 hours, greatly facilitating the need for temporary flow measurement in different occasions.
Second, the difference in function: the fixed ultrasonic flowmeter generally has 4-20mA signal output or RS485 and other functions for remote display, but it can only store the parameters of a pipeline inside; The portable ultrasonic flowmeter is only for on-site viewing of the flow at that time
With the cumulative flow in a short period of time, there is generally no output signal function, but in order to facilitate the measurement of the flow of different pipelines, it contains rich storage functions, and can store dozens of different pipeline parameters at the same time, and can be used at any time when needed. Ultrasonic flowmeter and electromagnetic flowmeter, because the instrument flow channel is not set up any obstruction, all belong to the unimpeded flowmeter, suitable for use in solving the difficult problem of flow measurement of a flowmeter, especially in the measurement of large runoff has more outstanding advantages
