I was wondering if there are any experts who specialize in the maintenance and repair of Emerson flowmeters?

It’s better to take it apart and have it checked with a standard device; if there is a large error, it can be corrected. Otherwise, even when it gets to the site, it shouldn’t be unable to function properly

Since it’s for measurement purposes, it must be placed on the testing table, right? How would you contact the repair service on your own? Find a qualified testing agency – it’s safe and reliable

Hehe, there’s a slight deviation – that’s totally normal. All flow meters have their own level of accuracy; there is an error associated with the flow meter itself, as well as an error associated with the scale. In my opinion, it’s normal for there to be a difference of around 100 to 180 pounds per load. The mass flow meters on our factory’s loading platforms and the scale always show a difference of around 100 pounds. Those at the loading platform consider the scale to be accurate while the flow meter to be inaccurate. The solution is to adjust the settings of the flow meter’s system; the coefficient used by Emerson can be adjusted between 0.8 and 1.2, with 1 being the normal value. If the readings from the scale are too high, increase the coefficient – this increased coefficient represents the additional weight divided by the total weight loaded. Conversely, the coefficient is reduced. Prerequisite: The mass flow meter should preferably be calibrated at zero point. Load it back onto the vehicle and see if there’s a difference.

Zeroing, zeroing, zeroing – it’s necessary to perform zeroing frequently. Drift at the zero position is an inherent problem of mass flow meters that operate on the vibrating tube principle; it’s like a genetic disorder, an incurable issue. If the zero point isn’t accurate, then such mass flow meters can’t offer any meaningful level of precision – their accuracy is completely worthless. . :lol

The readings for our company’s devices are also generally off by about 100 to 150 pounds; in a few cases they show readings of 300 to 500 pounds from time to time. We’ve adjusted the zero setting many times, but it doesn’t make any difference

Teacher, does this frequent zeroing refer to performing the calibration once for each load?

Rival. Zero the scale when conditions permit! It will only bring benefits, no drawbacks.
