Product Introduction
1. The probe has low power consumption, easy installation, easy positioning, wide application conditions, and output standard 4-20mA current signal. It can be used as a liquid level meter alone.
2. According to the working conditions, the probe can be selected IP68, anti-corrosion, explosion-proof, small blind zone, ultra-low power consumption, large-scale and other special models.
3. With digital filtering and echo recognition function, manual setting of fixed interference filtering function
4. The upgraded version adds HART protocol communication support, which makes up for the shortcomings of the two-wire meter without data output, and can directly communicate with HART field instruments.
