Q1: Can a vortex flow meter have perfect accuracy?
A1: In an ideal world, the flow readings from your process meter would be exactly correct, without any type of deviation. Unfortunately, this is not the case, and the errors inherent in measurement must always be identified, accounted for, and minimized as much as possible.
Q2: Does a vortex flow meter need to be calibrated?
A2: During the production of a flowmeter, several steps are required such as coil winding, lining processing, and electrode assembly. This series of operations can cause a certain amount of error and dispersion in the device, so a calibration process is required to correct the accuracy.
Q3: How often do vortex flow meters need to be calibrated?
A3: Magnetic recalibrates the flowmeter every two years (every two years), or at the minimum frequency specified by the manufacturer. The manufacturer's specified minimum frequency meter readings are pressure corrected and, if necessary, corrected for moisture content.
Tips: Is a flow meter bi-directional?
Flow meters can only detect the magnitude of the flow, not the direction of the flow. Also, calibrate the meter in the direction indicated by the arrow on the bottom of the meter. Please refer to the application note Reverse Flow Effect on TS General Flow Meters for reverse flow calibration.
