Radar level gauge is a universal radar level gauge, it is based on the principle of time travel measuring instruments, radar wave speed of light operation, operating hours can be converted into electrical signals through the electronic components. The probe emits a high-frequency pulse and travels along the cable. When the pulse encounters the material surface, it is reflected and received by the receiver in the meter, and the distance signal is converted to a level signal.
Guided wave radar level gauge is the best way to measure the liquid level; guided wave radar level gauge measurement is not affected by the shape of the tank; nor by the dielectric constant, temperature, pressure and density of the impact; guided wave radar level NIVELCO guided wave radar level gauge measuring range up to 24 meters, the applicable medium temperature range of -50 ℃ ∽ + 250 ℃, suitable pressure range up to 40bar; guided wave radar level gauge with a variety of probe types and materials to choose from; digital display to choose from.
Radar level gauges emit extremely short pulses of microwave energy that are transmitted and received through the antenna system. Running time can be converted into level signals by electronic components. Even with complex operating conditions, there are false echoes that can be accurately analyzed using the latest micro-processing techniques and commissioning software.
Input: The antenna receives the reflected microwave pulse and transmits it to the electronic circuit. The microprocessor processes this signal to identify the echoes generated by the micropulse on the material surface. The correct echo signal recognition by intelligent software to complete, the accuracy can reach millimeter. The distance D from the material surface is proportional to the pulse travel time T: D = C × T / 2.
Output: Set by entering empty tank height E (= zero), full tank height F (= full scale) and some application parameters, the application parameters will automatically adapt the meter to the measurement environment. Corresponds to 4-20mA output.
