Radar Level Transmitter

Radar Level Transmitter

Product overview

The radar water level sensor emits radar pulses through its antenna, which also receives the pulses reflected from the water surface and records the time. By measuring the time difference between the transmission and reception of the electromagnetic wave, the radar level meter calculates the distance to the water surface. The actual water level is then derived based on the sensor’s installation height, as shown in the diagram below:

h = H₁ – C·Δt / 2

Where:

• H₁ — Height from the channel bottom to the radar level meter (i.e., installation height)
• C — Propagation speed of electromagnetic waves (a constant)
• Δt — Time difference between the emitted and reflected signals

Key features

• Non-contact measurement effectively avoids interference from debris in the water.
• Adaptive filtering identifies surface fluctuations and resists wave interference, ensuring more accurate measurements.
• Low-power design with an average power consumption of only 0.3 W, enabling long-term operation on battery power.
• IP68 protection rating and salt spray corrosion resistance, making it suitable for harsh environments.
• Compact design, with overall dimensions of only 50 × 50 × 50 mm, for easy installation.

Applications

• Water level in drainage system manholes
• river water level
