The product
Pulsar burst radar – Technology
Pulse Burst Radar emits short bursts of energy to a liquid surface. Ultra-high-speed timing circuitry measures the time of the signal reflected off the liquid surface.
Sophisticated signal processing filters out false reflections and other background noises. The exact level is then calculated, by factoring in tank height and other configuration information. The circuitry is extremely energy efficient so no duty cycling is needed as with other radar devices. This allows the device to track high rates of level changes up to 4,5 m/minute (180″/min).

Operating principle
PULSAR transmitter technology is based on pulse-burst radar technology together with equivalent time sampling circuitry. Short bursts of 26 GHz microwave energy are emitted and subsequently reflected from the liquid level surface.
