Ultrasonic Level Transmitter HD1200


Advanced level sensing algorithm suppresses the noise level and artifacts and enabled stable measurement.

One main unit handles two sensors at once. Two different types of sensors can be installed and each may measures different range.

Data logging function to micro SD TM.

Flow measurement by measuring catchment level is possible.


Level control of liquid, powder or grains in a tank

Level measurement of pond, lake or river
