NYRD705 ( Stainless Steel )1.8GHz Guided Wave Radar Level Meter
NYRD705 Stainless Steel High temperature and pressure type 1.8GHz Guided Wave Radar Level Meter Level Transmitter
The guided wave radar level meter is a level meter based on the principle of time domain reflection (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. 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 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.

Measurement Range
Symbol explanation:
H---- Measurement range
L---- Empty tank distance
B---- The blind area at the top
E---- The minimum distance between the probe and the tank wall
The blind area refers to the minimum distance between the highest level of the material surface and the measurement reference point.
The bottom blind area refers to the distance near the cable bottom that cannot be precisely measured.
The effective distance is the one between the top blind area and the bottom blind area.
Note:Only when the material level is at between the top and bottom blind areas can a reliable measurement of the material level be guaranteed.
Installation Guide
The following installation guide is suitable for that of cable and rod probes for measurement of solid particles and liquid. The coaxial tubular probe is applied only to the liquid object.
Installation position:
Try to stay away from the outlet and inlet.
The meter should not touch the tank internal wall for metal tanks and plastic tanks. If it is a metal tank, the material level meter should not be installed at the center of the tank.
It is proposed to install at 1/4 of the silo diameter.
Probes of cable or rod types should keep a distance away from the tank wall not less than 30cm.
The probe bottom should be about 30mm to the tank bottom.
The probe should keep a distance not less than 200mm from the obstacles within the tank.
The sensor can be installed at the center of the tank top, if the bottom of the container is a cone, so the measurement can be taken to the tank bottom.
The picture on the right shows the rod-type radar installation diagram, mainly used for liquid level measurement.
Radar Level Meter Electricalconnections
◎ Supply voltage
(4 ~20)mA/HART(Two-wire)
The power supply and the output current signal share a two-core shielded cable. Refer to the technical data for the specific supply voltage range. For the intrinsically safe type, a safety barrier must be added between the power supply and the instrument.
(4~20)mA/HART(Four-wire)
The power supply and the current signal are separated, and each uses a two-core shielded wire. Refer to the technical data for the specific supply voltage range.
RS485/Modbus
The power supply and the Modbus signal are separated, and each uses a two-core shielded wire. For specific supply voltage range see technical data .
