Radar Level Meter

The GTRD series radar level meter is a radar product that utilizes the Frequency Modulated Continuous Wave (FMCW) principle, suitable for liquid level and powder level monitoring in applications such as sewage tanks and reservoirs. This product boasts an accuracy of up to ±1mm, a maximum measurement range of 120m, and a minimum blind zone of 0.2m. It supports 4-20mA two-wire and RS485 communication. It can be used in conjunction with display instruments to achieve functions such as tank bottom display, level alarm, and control.
