Is the accuracy rating of a metal rotameter affected by the power supply?

Project Overview

The accuracy level of a metal rotor flowmeter mainly depends on its design, manufacturing process, physical properties of the fluid (such as viscosity, density, temperature, etc.), flow state (such as flow range, pressure, turbulence, etc.), as well as installation and use conditions (Such as straight pipe length, vibration, verticality, etc.). The power supply is usually necessary to ensure the normal operation of the electronic components of the flow meter, but it usually does not directly affect the accuracy level of the flow meter.

However, unstable power supply or power supply voltage exceeding the specified range of the flow meter may cause the following problems:

1. Unstable operation of electronic components: This may affect the flow meter The signal processing and output, such as the accuracy of the 4-20mA current signal, will not change the basic principle of flow measurement and the accuracy of the mechanical part.

2. The flow meter fails to work properly: Extreme power supply problems may cause the flow meter to fail to start or operate abnormally, which will obviously affect the reliability of the measurement, but this effect is due to the failure of the equipment to work properly, and A reduction in the non-accuracy level itself.

Therefore, although the power supply itself will not directly affect the accuracy level of the metal rotor flowmeter, a stable power supply is one of the important factors to ensure the overall performance and accurate measurement of the flowmeter. During use, ensure that the power supply meets the technical requirements of the flow meter.
