What is the low-flow calibration mechanism of the fuel dispenser?

In fuel metering equipment, how to ensure accurate measurement under small flow conditions is a fundamental matter. With the development of technology and the increasing requirements for the accuracy of refueling data, the low flow calibration mechanism has become one of the key factors to ensure the measurement accuracy of the refueling machine. Below we will discuss the importance of the low-flow calibration mechanism and why it is introduced in the dispenser’s design.

1. Problems under low traffic conditions

In daily use, many gas stations will face low flow conditions, especially when some motorcycles require trace amounts of refueling. However, traditional mechanical flow meters may experience inaccuracies at low flow rates, primarily due to a loss of measurement accuracy due to low flow rates upon initial startup, which may result in inaccurate refueling volume calculations. The general tanker error-flow rate curve is shown below:

2. The role of the small flow calibration mechanism

To solve the measurement problem under low-flow conditions, the tanker needs to introduce a low-flow calibration mechanism. The main purpose of this mechanism is to improve the accuracy of the tanker in low-flow situations. Through some technical means, the small flow calibration mechanism can ensure good accuracy even under small flow rates.

3. High-precision sensors and digital technology

Implementation of low-flow calibration mechanisms generally involves specially designed sensors. These sensors have higher sensitivity and wider dynamic range, providing accurate data at low flow rates. In addition, digital filtering algorithms help eliminate noise in measurement data and ensure data stability.

4. Optimization algorithm and compensation calibration

To cope with the challenges under different flow rate conditions, high-order algorithms can be introduced in the tanker system. The algorithm monitors flow changes in real-time and automatically adjusts calibration parameters based on environmental factors. Through this calibration mechanism, the tanker can maintain high measurement accuracy under different working conditions.

5. Regular maintenance and calibration

The low-flow calibration mechanism is not a panacea and requires regular maintenance and calibration. In actual use, the tanker needs regular inspections to ensure that every component is working properly. This includes the detection of sensors and the updating of calibration parameters, to maintain the accuracy of the system under low flow conditions.

In summary, the low flow calibration mechanism is a key technology in the design of the gas station. It plays a vital role in improving the measurement accuracy of the gas station and ensuring the normal operation of users and the gas station business. By using high-precision sensors, high-order algorithms, and regular maintenance and calibration, the tanker system can maintain excellent performance in various refueling scenarios.
