MRF-10 radar level meter is a level sensor with HART protocol and current loop power supply. The measuring principle is based on radar technology, measuring the transit time of the signal reflected from the measured medium. The TOKYO KEIKI MRF-10 radar level meter is a loop powered liquid level gauge.
The MRF-10 radar level sensor is installed at the top of tanks or channels. It emits short microwave pulses to the level of liquid. As such pulses are reflected from level of liquid, they are received by the antenna and processed. The time between the emission and reception of the signal is then converted into the value of level of liquid.The MRF-10 radar level sensor is installed at the top of tanks or channels. It emits short microwave pulses to the level of liquid.
