Influence of dust and steam on ultrasonic level meter measurement result

Ultrasonic liquid level meter made in China is more and more widely used in various production processes of Jiuquan Steel due to its accurate measurement, small maintenance, reliable operation and high cost performance. It is recommended that users use the characteristics of the ultrasonic level gauge and the installation environment factors when using it. Measured media properties are recommended for use in conventional water level measurement and environmentally friendly solids measurement systems.

In the presence of dust and steam, the measurement accuracy of the ultrasonic level transmitter will be affected. For example, in the case of a user using an ultrasonic level meter to measure the raw coal bunker and raw coal level, since some coal dust will be generated during the raw coal bunker feeding and discharging process, the ultrasonic level transmitter will appear in practical applications. The loss of wave causes the meter to display zero or the level display to be lower than the actual value. This phenomenon is more obvious in winter. The reason is that in order to prevent the raw coal from being frozen, the staff uses steam to heat the material yard, which eventually causes some steam to emerge from the material after entering the warehouse. Since dust and steam absorb the pulse signal of the ultrasonic wave, most of the energy is absorbed and absorbed, and only a small part of the energy is returned, so the wave loss phenomenon often occurs, causing measurement deviation.

Solution: It is recommended to add a compressed air purging device to the outer edge of the ultrasonic probe to reduce the absorption of ultrasonic waves by a large amount of dust during blanking. The method can well block steam and dust from adhering to the transducer probe, and can also blow the ultrasonic transmission path with compressed air to ensure measurement accuracy. The scheme has achieved very good results in practical applications, so it has a good reference for the use of ultrasonic level gauges in such environments. welcome to contact us for cheap level meter price .such as ultrasonic level meter price cost.
