Two Wire Ultrasonic Level Meter The ultrasonic level mete is a digital level gauge controlled by a microprocessor. In the measurement, the ultrasonic pulse is emitted by the sensor (transducer), and the sound wave is reflected by the liquid surface and received by the same sensor or ultrasonic receiver, converted into an electrical signal by a piezoelectric crystal or magnetostrictive device, and transmitted and received by the sound wave To calculate the distance between the sensor and the surface of the liquid being measured Due to the non-contact measurement, the measured medium is almost unlimited, and it can be widely used for measuring the height of various liquids and solid materials. Suitable for various corrosive and chemical applications, with high precision, remote signal output, PLC system monitoring. Applicable measurement medium: Suitable for most liquid and powdery granular solids, weak acids, weak bases, strong bases, and strong acids below 40%. If in strong acid applications, anti-corrosion probes should be used. Gasoline oil Diesel needs to choose explosion-proof function When you select the range, remember to pay attention to the blind zone in Figure 1. The blind zone will be different for different ranges. Measuring Range 5M，Blind Area:0.4m Measuring Range 8M，Blind Area:0.4m Measuring Range 10M，Blind Area:0.5m Measuring Range 12M，Blind Area:0.5m Measuring Range 15M，Blind Area:0.6m In any of the following situations, pay attention: Liquid/solid with foam There are strong voltage, strong current, strong electromagnetic interference around, try to avoid high voltage, high current and strong electromagnetic interference Steam and dust Too high temperature and pressure
