The vibrating rod level switch product series uses patented single rod vibration technology to measure the level of powdered or granular materials in storage tanks, pipelines, or silos. Single rod measurement has many advantages compared to tuning fork measurement, such as measuring materials without clamping, bridging, or hollowing, and there will be no false alarms due to this. The patented hardened film measuring rod can withstand high vertical and lateral forces. We also have various structures of level switches, suitable for high and low limit alarms of low-density materials.
