Level gauges that utilize \"micro-vibration analysis\" and \"frequency-variable ultrasonic\" technology: they \"perform their designated functions excellently under specified conditions and within a set time frame.\" Put simply, they can function properly even when the temperature of the liquid medium ranges from -60°C to 220°C. The values for feeding, discharging, and mixing remain consistent with the predetermined values (for level gauges). They will trigger an alarm at 1001 mm and will never exceed 1002 mm (for level switches). For more information, visit http://www.dhechina.com/ueditor/php/upload/image/20181126/1543196358311203.jpg.
