Ultrasonic liquid level gauge is widely used in chemical, water treatment, water conservancy, food, food and other industries for level measurement. It is safe, clean, high precision, long life, stable and reliable, easy installation and maintenance, simple readings. The product adopts two-wire system, three-wire system or four-wire system. The power supply circuit and signal output circuit are independent. When using 24V DC power supply, a 3-wire cable can be used. The negative terminal of the power supply and the negative terminal of the signal output share a core. Line; When using AC 220v power supply, or when using DC 24v power supply, require power supply circuit and signal output circuit completely isolated, a 4-core cable should be used. DC or AC power supply, with 4 ~ 20mADC, high and low switching output.

    First, the impact of stirring on the ultrasonic level gauge
    In the scene, the liquid fluctuates greatly because of stirring. This situation will greatly affect the measurement of the ultrasonic level gauge. The correct solution should be to properly reduce the speed of the stirrer, or to install the static tube, which can effectively eliminate the ultrasonic vibration of the stirrer. Level gauge effect.
    Second, the impact of foam on ultrasonic level gauge
    When using the ultrasonic liquid level gauge to measure the liquid level, the foam interference can not be ignored. The foam properties can be divided into three types: dry, wet, and neutral; the dry foam can reflect the ultrasonic wave; the neutral foam can absorb the ultrasonic wave, reducing Reflects the ultrasonic amplitude; Therefore, when the liquid level foams, it will cause the measurement error of the ultrasonic liquid level gauge to be large, must pay attention to this in use.
