Q1: Can a turbine 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 turbine 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 turbine 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: Are there special connection requirements for flow meter analog transmission?
Yes, the analog signal ground circuit of the flowmeter is connected to the power supply ground inside the flowmeter. Therefore, your device must use a voltmeter or analog input circuit with differential input or floating ground. Failure to use this type of grounding will result in measurement errors.
