Parabolic Radar Level Gauge

1. Product Brief Introduction:

HQ-51L (HQ-8260P) parabolic antenna consists of a reflector and a feed source located at its focal point, forming an axisymmetric parabolic structure antenna. The main advantage of the parabolic radar level gauge is its high directionality, similar to a searchlight or flashlight, which converges microwaves in a specific direction into a narrow beam. Due to the narrow beamwidth and directionality of the HQ-8260P parabolic radar level gauge, it can measure well when there are many interferences inside the tank wall, without being affected by false echoes from interferences such as stairs. Suitable for measuring large range, high dust, high temperature, and low dielectric constant media in the cement, power, and steel industries. HQ-51L radar level gauges are suitable for non-contact, large range liquid/material level measurement installed on the top of containers.
