CR-6031 High Pressure Type
Combined capacitive measurement with tomography, series of CR-6031 intelligent liquid level meter for drum of boiler can achieve impact analysis over all the parameters detected in the drum including dielectric constant, compensation?temperature, pressure etc. After computation, microcomputer inside the meter can output signals within the industrial standard 4-20mA or RS485 digital signal for reference.
With real-time dynamic compensation, the running of the liquid level meter can be kept stable for a long time and will not be affected by temperature and pressure. As a cost-effective liquid level meter for drum, it can be used in all conditions such as, thermal power plants, steel plants, cement plants, etc. for the measurement of water level of boiler drum.
Two-wire system, 4-20mA current loop, with a resolution of 0.1 mm and accuracy higher than 1%.
With tomographic, it can make continuous measurement and compensation for dielectric constant variation of liquid and vapor mediums.
With patented automatic calibration technology, it can automatically align the zero and full points in the process of emptying and water-adding of the liquid level meter.
The measurement is true and reliable due to that the level meter is directly connected with the drum body of boiler and the capacitive sensor is in direct contact with the liquid.
The patented structure of steam condensing chamber can ensure the consistency of the temperature between the level meter and the boiler drum body to the maximum extent, so as to ensure the accurate of the water level measured. It can also effectively separate the steam from the water to prevent water drop on the surface of capacitive sensor, and avoid the impact of steam and water on the capacitive sensor.
Its inverted structure and automatic sealing function ensure the safety and reliability of the electrical parts.
It adopts advanced technologies for the whole parts, and is reliable and durable.
