The height of the liquid medium in the container is called the liquid level, and the instrument for measuring the liquid level is called a liquid level meter. The liquid level meter is one of level meters. Since the liquid level gauge is susceptible to the environment during use, the liquid level gauge is often matched with a corresponding sheath during actual use.

For example, in corrosive slurry, when in measurement, because the temperature of the sound wave emitting end of the measuring instrument is lower than the ambient temperature of the slurry, water vapor is condensed at the sound wave emitting end of the measuring instrument, the water vapor causes the sound wave to deviate and reflect when in emission, the measurement result is influenced, and in severe cases, the detection device cannot complete the measurement due to interference waves generated by the condensed water. Chinese patent publication No. CN201421347Y discloses an antifogging sheath for ultrasonic level meter, the antifogging sheath comprises flange and tubulose heating pipe, tubulose heating pipe and flange joint, the tubulose heating pipe contains flange center round hole. During detection, an external power supply supplies electricity to the anti-fog sheath, the temperature of a heating pipe of the anti-fog sheath is increased, and the temperature in the heating pipe is higher than the surface temperature of the detection slurry; because the sound wave emission tube of the ultrasonic liquid level meter is arranged in the tubular heating tube of the anti-fog sheath, and the surface temperature of the sound wave emission tube is higher than the surface temperature of the measured slurry, the surface of the sound wave emission tube of the ultrasonic liquid level meter is not condensed by water vapor, and the detection precision and accuracy are improved.
