Portable Ultrasonic Flow Meter is a handheld ultrasonic flow meter. The clamp-on sensor is used to measure liquid flow in industrial pipelines.

Features Of Portable Ultrasonic Flow Meter

1. Equipped with a magnetic mounting rail, which can be adsorbed on the outside of the pipe wall. Easy to install, saving time and cost of installation.
2. The measurement range is large, and a set of sensors can be used to measure pipe diameters in all ranges.
3. Newly added energy meter/cold (hot) meter function. It can be expanded to portable energy meter/cold (hot) meter.

Other forms of application of ultrasonic flowmeter:

1. The externally clamped ultrasonic flowmeter can realize non-contact flow measurement. Even if it is a plug-in or internally attached ultrasonic flowmeter, the pressure loss is almost very low, and it is convenient and economical to measure flow.
2. The ultrasonic flowmeter can measure water, gas, oil and various media, and it has a wide range of applications.
3. The manufacturing cost of ultrasonic flowmeter has almost nothing to do with the caliber. The price is reasonable on the large diameter flow measuring stone. Comprehensive competitive advantage with easy installation and use
4. Portable ultrasonic flow meters can be used to measure flow in pipelines with different pipe diameters and different materials. Used as a standard table for online calibration, comparison or period verification.
5. Ultrasonic flowmeter has the convenience of inverse source based on two basic physical quantities of length and time. It can be expected that flow meters that surpass other principles will become flow standards or carriers of flow standards.
6. Ultrasonic flowmeter has extremely low power consumption and long battery power supply time. Advanced intelligent host is easy to carry out network wireless communication, and its application prospects are broader.

Common faults and treatment in the use of ultrasonic flowmeter

Ultrasonic flowmeter is a non-contact instrument. It can not only measure the medium flow of large pipe diameter, but also measure the medium that is difficult to contact and observe. The measurement accuracy is very high, and it is rarely affected by various parameters of the test medium. In particular, it can solve the flow measurement problems of strong corrosive, vision, radioactivity and flammable and explosive media that other instruments cannot do.

Common faults and treatment in the use of ultrasonic flowmeter

1. Failure phenomenon: The instantaneous flowmeter fluctuates greatly.
   ⑴ Cause of failure: large fluctuations in signal strength; large fluctuations in the measured fluid itself.
   ⑵Processing method: adjust the probe position and increase the signal strength (maintain above 3%). Ensure the signal strength is stable. If the fluid fluctuates greatly, the position is not good. Re-select the points to ensure the working conditions of the first 10D and the 5D.
2. Failure phenomenon: Low signal of external clamp ultrasonic flowmeter.
   ⑴Cause of failure: The pipe diameter is too large or the pipe fouls seriously or the installation method is wrong.
   ⑵ Treatment method: Use plug-in probes for those with too large pipe diameter and serious scaling. Re-select the installation method.
3. Failure phenomenon: The signal of the plug-in probe decreases after a period of use.
   ⑴Cause of failure: The probe may be offset or the scale on the probe surface may be thick.
   ⑵ Treatment method: readjust the probe position. Clear the emitting surface of the probe.
4. Trouble phenomenon: No display when booting.
   ⑴Cause of failure: The power supply attribute does not correspond to the rated value of the instrument or the fuse is blown.
   ⑵ Treatment method: Check whether the power supply attribute corresponds to the rated value of the instrument. Whether the fuse is blown. If the above problems are not found, notify the factory professionals to deal with.
5. Trouble phenomenon: The instrument has only backlight and no character display after power on.
   ⑴Cause of failure: Generally, the program chip is missing.
   ⑵ Treatment method: notify the factory professionals to deal with.
6. Failure phenomenon: Ultrasonic flow meter cannot be used under strong interference on site.
   ⑴ The cause of the fault: The power supply has a large fluctuation range, or there are frequency converters or strong magnetic field interference or the grounding wire is incorrect.
   ⑵ Treatment method: Provide stable power supply to the instrument. Or install the meter away from the inverter and strong magnetic field interference. Or set the grounding wire standardly.
