Nuclear slurry level gauge and double flange
Thread Content
There is a project for which a gamma-ray level gauge was specified in the design, but given the complexity of the procedures and concerns over future maintenance difficulties, there is plans to switch to a double-flange design. I would like to ask everyone: what are the actual differences between the two in terms of usage? Do you think it’s necessary to switch? Thank you!
Is there a connection between these two watches? With such a question, who can answer it? You need to send over the process parameters so that everyone can discuss whether it’s possible to switch to another table
They are all used to measure the liquid level in the reaction vessel. Since the reaction vessel is equipped with a stirrer, the designers opted for nuclear density meters. Are double flanges useful for measuring the level of liquids with agitation?
I think for measuring the level of a liquid with stirring, differential pressure or double flanges can all be used, right? The only difference is to avoid stirring inside the device, making sure not to damage the instruments. Personal opinion!
Flange-mounted meters can be used for measurement; however, stirring may cause fluctuations in the liquid level. If a stable signal is required, considering the use of damping filters might be advisable.
The reaction vessel is equipped with an agitator; it is advisable to avoid using isotope level gauges for measurement, as the gamma rays traveling from bottom to top in a diagonal direction toward the ionization chamber are blocked and disrupted by the agitator, resulting in large fluctuations in the counting rate and thus large variations in the output signal of the instrument. Additionally, the maintenance and calibration of isotope instruments require special work permits, even though it is not done very often; moreover, the vast majority of people are reluctant to get near them. In contrast, using a double-flange gauge for measurement is the better option, as the regular fluctuations in the liquid level caused by its undulations allow the damping to be increased to an appropriate level, as mentioned on floor 6. If the gas-phase medium has relatively stable light transmittance and is not prone to condensation, a non-contact level gauge can also be considered for measurement.
