China Smart Level Sensor, Meter 4-20mA

China Smart Level Sensor, Meter 4-20mA Description China Smart Level Sensor, Meter 4-20mA Radar level sensor emits a very narrow microwave pulse, the pulse to the speed of light in the space, encountered the surface of the measured medium, part of its energy is reflected back, the same antenna to receive. The time interval between the transmitting pulse and the receiving pulse is proportional to the distance from the antenna to the surface of the measured
