Single - ended Ultrasonic Flow Velocity Meter KGD - LL - 502 Product Introduction Based on the ultrasonic principle, the KGD - LL - 502 product
effectively solves the measurement difficulties such as unstable
flow field, low and uneven flow velocity distribution commonly
existing in pipelines through a non - contact measurement method.
It can maintain continuous and real - time stable monitoring in the
harsh environment of high temperature, high humidity, high dust,
and viscous impurities during flue gas emissions, meeting the
measurement needs of municipal and industrial applications. It has
strong versatility and can work independently or be integrated into
the CEMS system. The KGD - LL - 502 adopts a single - ended opening
installation method, which calculates the linear average velocity
of the radial airflow in the flue by using the ultrasonic
propagation time difference, and has higher accuracy compared with
other measurement methods.
Product Features - Capable of measuring low flow velocities, with a measurement lower
limit of up to 0.1m/s.
- Linear average flow velocity measurement based on the ultrasonic
principle, with an accuracy of ≤±2%F.S.
- Strong anti - interference ability. The autocorrelation
demodulation technology effectively overcomes on - site noise
interference.
- Convenient single - ended opening installation. Replacing old
detection equipment does not require repeated opening of holes.
- Wide measurement diameter range, supporting installation on
pipelines with a diameter of over 0.5m.
- High system integration. It can simultaneously measure the
temperature, pressure, and flow velocity of the gas.
- Suitable for gas flow measurement in acid - containing and water -
containing gases. It is not affected by changes in gas components
and requires less maintenance.
- The parts of the whole machine in contact with the gas are made of
corrosion - resistant materials, which can effectively resist flue
gas corrosion.
- Adopts an embedded data processing method and has functions such as
calibration, configuration, query, and diagnosis.
