Magnetic inductive flowmeter calibration specification

Project Overview

一、Appearance and record checking

• 1、Check the appearance of the magnetic inductive flowmeter to ensure that there is no visible damage, deformation or corrosion.
• 2、Record basic information such as the model number, specifications, manufacturer, and factory date of the magnetic inductive flowmeter.

二、Installation and Environmental Confirmation

• 1、Verify that the magnetic inductive flowmeter is installed in a location that meets the design requirements and that there are no obvious sources of external interference.
• 2、Check the environment around the flowmeter to ensure that the temperature, humidity and other environmental conditions meet the requirements of the product specification.

三、Preliminary

• 1、Prepare tools, meters and calibration equipment required for calibration.
• 2、Check that the flow calibration equipment is in good condition and calibrate it to a satisfactory state.

四、Verification procedure

• 1、In accordance with the test programme, the test flow points are set and the test equipment is adjusted to produce the appropriate flow rate.
• 2、Record the actual flow value at each calibration point and the output value of the electromagnetic flowmeter.
• 3、Repeat the above steps until all calibration points are completed.

五、Error calculation

• 1、Calculate the error value for each calibration point based on the actual flow value and the output value of the magnetic flowmeter.
• 2、Analyse the error values to determine if the magnetic flowmeter meets the error requirements.

六、Calibration
