Stainless Steel NYRD702 Radar Level Transmitter 4-20mA/HART(Two Wire/Four Wire)
Stainless Steel NYRD702 Radar Level Transmitter
The guided wave radar level meter is a level meter based on the principle of time domain reflection (TDR).Stay away from exports and imports. The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. For metal and plastic cans, the meter shall not touch the inner wall of the tank. If metal tank, level gauge should not be installed in the center of the tank.Part of the pulse of the level meter is reflected to form an echo and return to the pulse transmitter along the same path. The diagram on the right shows the rod-shaped radar installation, which is mainly used for liquid level measurement.The distance between the transmitter and the surface of the measured medium is proportional to the propagation time of the pulse during that period, and the liquid level height is calculated.Sensor can be installed in the center of the roof, if the bottom of the container for cone, can measure in the tank bottom.
