How to calibrate steam flow online
Thread Content
A Pitot tube flow meter is being used in practice to measure medium-pressure steam; the pipeline diameter is DN500, and the actual flow rate is on the low side. I would like to know what methods can be used to online calibrate it and compare it with the actual steam flow rate
Cannot mark. You just need to install another flow meter. For example, V-cones, porous orifice plates – don’t use some kind of bar

If financial conditions permit, purchasing an imported clamp-on ultrasonic flow meter allows for on-site comparison. It cannot be calibrated on-site.
The premise is that the medium can be measured, and ultrasonic waves for measurement can be found
Orifice meters inherently have low precision; for larger diameters, use standard orifice plates and standard nozzles along with temperature and pressure compensation. Avoid using non-standard flow meters such as V-cone or balanced types, as it is not possible to perform accurate flow calibration for gases with such non-standard diameters.
Look carefully at the issue when answering – what the original poster is asking about is the steam flow rate. Setting aside accuracy and signal quality for now, what imported ultrasonic device can be used for online comparison?
If accurate measurement is difficult to achieve, you can choose our company’s plug-in anti-vibration vortex flow meter, which offers high precision.

If online calibration is necessary, there are ways to do it; either by spending money to install a bypass pipe and a large water tank so that the steam can condense into water and its weight can be measured, thereby determining the measurement error of the flow meter with accuracy.
