Publish Time: 2024-04-26
The Precision Liquid Injection Metering Pump is able to achieve precise flow measurement through its unique working principle and structural design. Here are the main ways the Precision Liquid Injection Metering Pump accurately measures flow data:
Mechanical metering method: This is the basic method of metering pump flow measurement. It is based on traditional physical quantities, such as mass, volume, length, etc., combined with the definition of certain basic units, to derive the flow formula of the metering pump. The measurement results of this method are highly accurate, but there are some uncontrollable factors that may affect the accuracy.
Electromagnetic flowmeter method: This is a high-precision method that uses electromagnetic phenomena to measure. The electrodes generate electromagnetic measurement signals for the liquid flowing through the conductor to measure the flow rate. This method has high measurement accuracy, but the cost is relatively high.
Volumetric measurement: The Precision Liquid Injection Metering Pump is equipped with a precise metering chamber. Through the reciprocating motion of the piston or screw, the volume in the metering chamber is changed, thereby accurately measuring the amount of liquid delivered. This mechanical measurement method ensures high flow accuracy.
Control system calibration: The control system of the metering pump usually has a calibration function, which can be adjusted and calibrated according to actual needs to further improve the accuracy of flow measurement.
Cooperation of sensors and actuators: The control system of a metering pump usually contains components such as sensors and actuators. These components can monitor the working status of the pump in real time, such as flow, pressure, etc. and perform precise control based on preset parameters to ensure flow. precise measurement.
To sum up, the Precision Liquid Injection Metering Pump achieves accurate flow measurement by combining a variety of high-precision measurement methods and technical means. In practical applications, users can choose appropriate measurement methods according to specific needs and scenarios to ensure the accuracy and reliability of measurement results.
