Selection of metal tube rotor flowmeter, first of all, to understand the metal tube rotor flowmeter manufacturing enterprises to implement the product standards, especially on the accuracy of the provisions of the provisions of the display scale.
At the same time, it is necessary to combine the process requirements in flow measurement, especially in the case of high measurement or control requirements, intuitive scale display, and high medium viscosity, to choose a metal tube rotor flowmeter that can directly display the medium flow and has density and viscosity compensation performance. Because the conversion and calibration of the scale are completed according to the medium conditions.
Choose the right material for the measuring parts. Generally, you should choose a material with good corrosion resistance. Only by ensuring that the float and measuring parts are not corroded by the medium for a long time can we ensure that the product can work at the factory accuracy requirements for a long time. If the normal working flow is lower than 50% of the range, the error at the measuring point will increase, which is not conducive to the control accuracy.
This is especially important for manufacturers with density and viscosity correction capabilities. This is because differences in density or viscosity will directly affect the calibration of the flow scale. For flow meters that directly display the water or air flow scale under calibration conditions, the manufacturer may be required to provide calibration data and flow meter certificates. When the meter is actually used, the density correction must be performed manually based on these calibration data and calculations.
For metal tube rotor flowmeters that require control functions, try to choose products with communication functions. When the medium conditions change, the product's communication function can be used to adjust the signal on site to maximize product accuracy. Users who have the conditions can re-inspect the meter according to the flow calculation book and calibration records provided by the flow meter manufacturer.
The above is the "Principles of Calibration and Measurement Accuracy of Metal Tube Rotor Flowmeter" shared by the metal tube rotor flowmeter manufacturer. Thank you for watching. If you have any questions, you can consult online or leave us a message. We will answer you wholeheartedly.
