Analysis of factors affecting the measurement accuracy of water level meter:
Instrument factors
Resolution: The resolution of the water level meter determines the minimum water level change value that it can distinguish. Water level meters with low resolution cannot accurately measure tiny water level fluctuations, and will produce large errors in scenarios that require high-precision measurements.
Quality of electronic components: The quality and performance of electronic components inside the water level meter, such as amplifiers and analog-to-digital converters, will also affect the measurement accuracy. Low-quality electronic components may introduce noise and interference signals, resulting in unstable or inaccurate measurement results.
External environmental factors
Temperature changes: Changes in temperature will affect sensors and measurement media. For example, the pressure sensor of a pressure-type water level meter will be affected by temperature, resulting in measurement errors. At the same time, changes in water temperature will cause changes in water density, which in turn affects the water level measurement results based on the pressure principle.
Water quality: If the water body contains a large amount of impurities, suspended matter or is corrosive, it may clog or corrode the sensor, affecting the normal operation of the sensor. For example, if the probe of an ultrasonic water level meter is covered with impurities, it will affect the transmission and reception of ultrasonic waves, resulting in measurement errors.
Water flow velocity: For some types of water level meters, such as float-type water level meters, excessive water flow velocity will produce impact force on the float, so that the float cannot accurately follow the water level changes, thus affecting the measurement accuracy.
Atmospheric pressure fluctuations: Changes in atmospheric pressure will affect the measurement results of pressure-type water level meters. Because pressure-type water level meters measure the relative pressure of water bodies, fluctuations in atmospheric pressure will be misjudged as changes in water levels.
Installation and use factors
Installation location: The installation location of the water level meter is crucial to measurement accuracy. If the installation location is unreasonable, such as near turbulent water flow, water outlets or areas with vortices, the measurement results will be disturbed by the water flow and inaccurate.
Installation method: Different water level meters have different installation requirements. If the installation method is incorrect, the measurement accuracy will be affected. For example, if the probe of the pressure-type water level meter is not placed vertically during installation, the measured pressure value will be inaccurate.
Calibration and maintenance: The water level meter needs to be calibrated and maintained regularly to ensure its measurement accuracy. If it is not calibrated for a long time, the instrument may deviate. Improper maintenance, such as failure to clean the dirt on the sensor surface in time, will also affect the measurement accuracy.
Data transmission and processing: During the data transmission process, signal interference, loss or transmission delay may affect the accuracy of the measurement data. Unreasonable data processing algorithms may also lead to deviations in measurement results.
Detailed Photos
It is made of stainless steel and has water resistance contact points installed inside. When the contacts touch the water surface, the receiving system will be connected. When the contacts leave the water surface, the receiving system will be automatically closed.
The steel ruler and the conducting wire are combined into one by plastic technology, which not only prevents the steel ruler from rusting, but also simplifies the operation process, making the measurement and reading more convenient and accurate.
It consists of a sounder and a test button. The sounder emits a continuous buzzing sound from the buzzer. There is a test button on the front panel, which is mainly used to test whether the entire receiving system can work normally. If the battery is about to run out, the buzzer sound will become smaller. If you need to continue using it, please replace the battery of the same specification. (9V 6F22)
Winding reel part: It consists of a winding disc and a bracket. The receiving system and battery compartment are placed on the front of the winding reel panel, and a steel ruler cable is wound outside the cavity.
