Precautions for using external level gauges

Thread Content

Level measurement is an important task in industrial production, and it is also one of the most crucial parameters in this field. Along with temperature, pressure, and flow rate, it is known as one of the \"four key parameters in industry\". Over the years, external level gauges have also been increasingly used in more industries, with significant improvements in terms of measurement accuracy, stability, and reliability! Dinghua Electronics’ sonar-type external level gauges are currently widely used in industries such as petroleum, petrochemicals, chemicals, military fuel depots, storage and transportation, power generation, and pharmaceuticals. They are particularly popular for measuring levels in areas containing hazardous chemicals, and are highly praised by users due to their ability to operate without drilling holes, initiating fires, emptying tanks, or shutting down production processes. So, what precautions should be taken when using external-mounted level gauges? The higher the viscosity of the medium being measured, the faster the sonar signal attenuates as it propagates, which affects both the measurement distance and the stability of the signal. The liquid is not a suspension or emulsion; it cannot hold large amounts of solids and bubbles suspended in it. The container wall at the location where the probe is installed must be made of a rigid material that can transmit vibrations effectively. For example: carbon steel, 16MnR, stainless steel, various hard metals, fiberglass, rigid plastics, ceramics, glass, hard rubber, and other materials or composite materials. Installing the probe requires a mounting surface on the container wall with dimensions of Φ80mm and a levelness of less than 5°. The surface flatness of the installation surface should be 0.05 mm, and the surface roughness should be 1.6. Intense liquid influx impacts and continuous rotational stirring of the medium under test can prevent the sonar signals from being transmitted properly, resulting in discontinuous level measurements. During installation, for spherical tanks, the measurement probe must be installed as close as possible at the vertical center position, to ensure that the signals emitted by the probe are perpendicular to the surface ； During maintenance, it is essential to remember that in explosion-proof areas, explosion-proof boxes must be used ； When setting parameters, it is essential to use a dedicated magnetic pen to avoid accidental operations that could affect production.
